Description

Method and device for producing animation using an animation library

[0001] The present invention relates to a method and apparatus for producing animation using an animation library, and more specifically, to a technology for sharing and reusing animation data in the production of 3D animation content using a 3D graphics engine.

[0002] Animation production is carried out through a very complex process. Conventional animation production is produced in a linear manner using Digital Content Creation tools (DCCs) that handle 3D graphics. Specifically, the current animation production method generates the final animation image by sequentially performing stages such as modeling, animation, rendering, and compositing.

[0003] This method of animation production is carried out by applying camera layout techniques used in film. In other words, various existing camera work methods are often used as is to create unique dramatic effects in the camera work. This directorial style is sometimes referred to as mise-en-scene and can be used repeatedly across different works.

[0004] Meanwhile, a game engine is software originally intended for developing games, and it provides various functions such as a rendering engine that expresses 3D graphics, a physics engine that produces physical effects, animation, artificial intelligence, and networks.

[0005] The graphics of such game engines are expressed by receiving data implemented through modeling, known as assets, and rendering it. These assets form the background or characters of the video, and the character's performance can be composed by receiving the actual actor's performance through a motion capture system and a face recognition system, mapping it onto the character, and implementing it as the character's performance.

[0006] Therefore, such game engines can be utilized as production tools for movies, and can be used for previsualization before actual filming. If the modeled assets are indistinguishable from real life, they may also be used as actual film production tools.

[0007] As such, game engines can be utilized as animation production tools; if the angle and sense of distance of the screen are captured through camera movement, just as with actual filming with a camera, the screen can be composed with the exact feel of actual filming, which will be very advantageous for animation production.

[0008] Meanwhile, with the advancement of animation-related technologies added to game engines, the demand for sharing and reusing animation data is expected to increase.

[0009] Building an animation library is essential when performing animation keying and real-time rendering simultaneously on a game engine viewport, as this eliminates several steps of data transfer.

[0010] With the emergence of technology that enables direct key animation work within game engines, the need for sharing and reusing animation data within game engines is increasing. Although game engines have built-in features for saving Control Rig Pose assets, they are inconvenient as they require users to select individual controls, and the UI and UX for creating and applying pose assets are somewhat complex. Furthermore, there are no functions for saving or applying animations other than poses.

[0011] Embodiments of the present invention aim to provide a method and apparatus for producing animation using an animation library for sharing or reusing animation data by utilizing a 3D graphics engine-based animation library in the production of 3D animation content.

[0114] In step S120, the animation production device (100) performs a rigging step. The animation production device (100) riggs the 3D model by connecting a skeleton or structure to the generated 3D model so that the 3D model can move.

[0115] In step S130, the animation production device (100) performs a look-deb step. The animation production device (100) creates a visual style of the 3D model by applying at least one of lighting, shading, color, pattern, and texture to the 3D model.

[0116] In step S140, the animation production device (100) performs an animation step. The animation production device (100) adds movement to the rigged 3D model to create a scene in which the 3D model moves.

[0117] Herein, at step S141, the animation production device (100) further includes an animation library setting step of setting pose data or animation data of a 3D model using an animation library based on a 3D graphics engine (e.g., Unreal Engine, Unity Engine, etc.).

[0118] In step S150, the animation production device (100) performs a lighting step. The animation production device (100) sets the light in the scene where the 3D model moves.

[0119] In step S160, the animation production device (100) performs a visual effect step. The animation production device (100) generates a special effect pre-set for the moving scene in a digital environment.

[0120] In step S170, the animation production device (100) performs a rendering step. The animation production device (100) combines all elements from the modeling step, rigging step, lookde step, animation step, lighting step and visual effect step and outputs them as an image or video file.

[0121] In step S180, the animation production device (100) performs a compositing step. The animation production device (100) combines multiple render passes and visual effects generated in the previous step of the rendering step to produce a final image.

[0122] FIG. 3 is an example drawing for explaining the modeling step in an animation production method according to one embodiment of the present invention.

[0123] As illustrated in FIG. 3, an animation production device (100) according to one embodiment of the present invention performs a modeling step.

[0124] The animation production device (100) performs the task of shaping all characters, environments, props, etc. that appear in the animation in a three-dimensional space.

[0125] The animation production device (100) performs the step of creating a basic three-dimensional model. The animation production device (100) creates approximate proportions and shapes using common geometric shapes (e.g., cube, cylinder, sphere, etc.).

[0126] The animation production device (100) grasps the overall structure and proportions of the 3D model and outlines the model. The animation production device (100) can work on the 3D model only in a rough form and not in a precise manner during the modeling stage.

[0135] As illustrated in FIG. 5, an animation production device (100) according to one embodiment of the present invention performs a Look Development step.

[0136] The animation production device (100) applies lighting to a 3D model and performs a look-down step by setting the reflectivity, transparency, refraction, etc. of the surface. Here, shading can determine how the 3D model receives light and how it reflects it.

[0137] The animation production device (100) can make the appearance of a 3D model look realistic. The animation production device (100) can enhance realism by adjusting effects such as the surface sparkling or shadows being created by light.

[0138] The animation production device (100) can perform the process of applying color and texture to the model. The texture can be applied to the model in the form of a 2D image to represent the surface texture, color, pattern, etc.

[0139] UV mapping is a crucial process in 3D modeling, involving the task of unfolding the surface of a 3D model onto a 2D plane to enable the application of textures. Simply put, it can be described as the process of "unfolding" a "surface" in 3D space into a 2D image space. This process is essential primarily for texturing and detailing, playing a key role in adding realistic details to the model.

[0140] The animation production device (100) can apply textures to make the model look realistic, thereby enabling detailed implementation of the surface texture of the character or environment. For example, the animation production device (100) can apply textures such as skin, clothes, wood, and walls.

[0141] FIG. 6 is an example drawing for explaining the animation step in an animation production method according to one embodiment of the present invention.

[0142] As illustrated in FIG. 6, an animation production device (100) according to one embodiment of the present invention performs an animation step.

[0143] The animation stage is one of the most important stages in the 3D animation production process, and it is the process of creating scenes in which characters and objects move vividly. In this stage, the animation production device (100) adds movement to all rigged models and can create movements that are expressive and emotional. Animation is mainly implemented using two main methods: keyframe animation and motion capture. Through this, the animation production device (100) can give 3D models realistic and natural movements.

[0144] The animation stage is an important task in 3D animation production that gives life to characters and objects. In the animation stage, the animation production device (100) can set major movements through keyframe animation and add natural movements using motion capture. Additionally, the animation production device (100) can define major movements through blockout and, through fine-tuning and polishing, finally complete a smooth and realistic animation. All of these processes require meticulous work to control the details of timing, emotions, and movements, and are important stages that determine the quality and effect of the entire animation.

[0145] FIG. 7 is an example drawing for explaining the lighting step in an animation production method according to one embodiment of the present invention.

[0146] As illustrated in FIG. 7, an animation production device (100) according to one embodiment of the present invention performs a lighting step.

[0147] The lighting stage plays a crucial role in 3D animation production, involving the setting of light within a scene to impart a final atmosphere, emotion, and sense of realism. Lighting significantly influences the visual quality of an animation and allows for direction that reflects the physical characteristics of the real world while matching the visual style of the work.

[0148] The lighting stage is an important process in setting the mood and emotion of a scene in 3D animation. An animation production device (100) can utilize various lighting techniques, such as key light, fill light, and back light, to emphasize the timing, emotion, and depth of each scene, and to maximize visual effects through contrast and color tones created by light and shadow. The lighting stage can play an important role in defining the style of the animation and enhancing the overall sense of immersion.

[0149] And an animation production device (100) according to one embodiment of the present invention performs a visual effect step.

[0150] The Visual Effects (VFX) stage plays an important role in the 3D animation production process and is the work of digitally implementing various special effects that are difficult to realize in the real world.

[0151] Simulation, which is a core part of the visual effects stage, is the process of implementing specific effects in a digital environment based on physical laws. This may include water, smoke, explosions, fire, thunder, clouds, and destructive elements. The animation production device (100) can create very realistic movements through physical simulation using computer software in the visual effects stage.

[0152] The animation production device (100) can implement complex natural phenomena that cannot appear in the real world or movements that do not appear realistically in a virtual environment during the visual effect stage.

[0153] The visual effects stage is a crucial process for implementing realistic or imaginative special effects in 3D animation. It is a technical process that realistically reproduces natural phenomena, physical changes, and fantasy elements, enhancing audience immersion and improving the visual quality of the animation. This process includes simulation, particle systems, compositing, and post-processing.

[0154] And an animation production device (100) according to one embodiment of the present invention performs a rendering step.

[0155] Rendering is a crucial stage in 3D animation production where all elements—such as models, textures, lighting, and animation—are finally combined to produce a 2D image or video file. This process involves calculating all visual elements of a 3D scene on a computer and converting them into a final image, serving as a core task that determines the visual quality. Rendering is typically time-consuming and requires extensive calculations to achieve very high-quality results.

[0156] The animation production device (100) may include a process of converting a 3D scene into a 2D image or animation during the rendering stage. The animation production device (100) may generate realistic and detailed images by utilizing various rendering techniques such as ray tracing, scanline rendering, and path tracing during the rendering stage. In this process, it is important to properly balance rendering speed and quality through various tasks such as optimization and post-processing.

[0157] Afterwards, the animation production device (100) according to one embodiment of the present invention performs a compositing step.

[0158] The compositing stage is one of the final stages of 3D animation production, and is a process of synthesizing various visual elements to create a final image. The animation production device (100) can combine multiple render passes generated in previous stages, such as 3D modeling, texturing, lighting, animation, and rendering, in the compositing stage to ultimately enhance the visual completeness and add desired effects.

[0159] The compositing stage is closely related to video editing and visual effects (VFX), and the animation production device (100) can adjust the mood, color tone, lens effects, etc. of the scene mainly through post-processing. In this process, various visual elements are combined to create the final video, playing an important role.

[0160] The compositing stage is a post-processing step in 3D animation production, and is an important process that combines various render passes and visual effects to complete the final image. The animation production device (100) can establish the style and atmosphere of the final video through lens effects, color correction, visual effects, etc., during the compositing stage. The compositing stage can play an essential role in realistically realizing the 3D scene.

[0161] FIG. 8 is a diagram showing an animation library process in an animation production process using an animation library according to an embodiment of the present invention.

[0162] As illustrated in FIG. 8, an animation production process according to one embodiment of the present invention includes an animation library process (141). The animation library process (141) can set pose data or animation data of a 3D model using an animation library based on a 3D graphics engine.

[0163] FIG. 9 is a diagram showing the operation of a tool in an animation production method according to one embodiment of the present invention.

[0164] As illustrated in FIG. 9, an animation production device (100) according to one embodiment of the present invention can work with pose data or animation data using an animation library based on a 3D graphics engine.

[0165] Here, the Animation Library based on a 3D graphics engine is a tool designed to enable tasks such as saving, changing, and applying pose data or animation data using the control rig system of the 3D graphics engine. The control rig can move bones and meshes at once.

[0166] The control rig of the 3D graphics engine is a powerful tool for character animation that allows rigging and animation to be set up and manipulated in a node-based manner. Through this, the animation production device (100) can visually produce or adjust the character's pose, movement, expression, etc., without programming.

[0167] Here, in 3D graphics engines, a node refers to a functional unit block used in visual scripting or animation tasks. Simply put, a node is a small "component" that performs specific tasks or actions, and by connecting individual nodes, an overall operation or logic can be constructed.

[0168] FIG. 10 is a flowchart illustrating an animation process using an animation library in an animation production method according to an embodiment of the present invention.

[0169] In step S210, the animation production device (100) uploads control rig key data via the control rig API.

[0170] In step S220, the animation production device (100) analyzes and stores control rig key data of the user-selected section. Here, regarding the user-selected section, the library pose saving operation requires only the current time because it saves only a single frame, whereas animation saving requires a certain section.

[0171] Below, the detailed steps for step S220 will be explained.

[0172] In step S221, the animation production device (100) analyzes the track of the asset.

[0173] In step S222, the animation production device (100) stores key values ​​frame by frame. Here, the key values ​​may include the type of the channel, the interpolation mode of the key existing in the channel, and the actual value. The key values ​​may be stored in JSON format.

[0174] In step S223, the animation production device (100) performs a key reduction operation on the keys stored for each frame. Here, the key reduction operation refers to an operation where, when multiple keys exist in a single control rig track, if the values ​​of the keys are all the same, only the first key is kept and all the others are deleted. In this way, a channel with a constant value across the entire frame range is determined to be static.

[0175] In step S224, the animation production device (100) saves (exports) the key.

[0176] In step S225, the animation production device (100) selects a target selection method. For example, the animation production device (100) may select an Outliner, a Viewport, or a Sequencer as the target selection method.

[0177] In step S225, the animation production device (100) can analyze the stored key data.

[0178] In step S226, the animation production device (100) can reconfigure the key in the sequencer. Here, the animation production device (100) can analyze the stored key through the Key Exporter module and generate the key in the sequencer through the Key Importer module.

[0179] FIG. 11 is a diagram showing a portion of control rig data stored in an animation production method according to one embodiment of the present invention.

[0180] A control rig-based handle refers to a function that controls the movement (e.g., pose, animation, etc.) of a character or object using a control rig system of a 3D graphics engine. An animation production device (100) can provide the user with a type of interface or workflow that can create and modify poses based on the character's skeleton and manipulate animation data.

[0181] Here, we will explain the key concepts of control rig-based handles.

[0182] To explain Handles, they are manipulation points that allow direct control of specific parts of a character or object. For example, Handles represent the ability to select joint areas, such as a character's hands, feet, or head, to adjust their position or rotation.

[0183] To explain node-based operation, the control rig system uses nodes to control movement or animation. For example, an animation production device (100) can define an action such as "moving hand position to this point" as a node and connect it with other nodes to create an animation.

[0184] To explain the role of the handle, the handle can not only move the character's joints (e.g., elbows, knees) but also help to easily create complex poses. The animation production device (100) can produce precise animations by combining multiple handles.

[0185] To explain the frame-unit control operation, the animation production device (100) can set the position, rotation, scale (size), etc. of a corresponding part in a specific frame through a handle. The set data can be saved as a key and recorded on an animation track.

[0186] The advantages of a control rig-based handle are as follows.

[0187] The animation production device (100) can perform intuitive control operations through a control rig-based handle. Since the animation production device (100) sets movements by directly manipulating the joints or bones of a character, it can work visually and intuitively.

[0188] The animation production device (100) can perform real-time editing operations through a control rig-based handle. The animation production device (100) can check the results immediately while editing the animation in real time.

[0189] The animation production device (100) can be reused through a control rig-based handle. The animation production device (100) can reuse the set handle and rigging data for other characters or animation work.

[0190] The animation production device (100) can produce precise animations through a control rig-based handle. The animation production device (100) allows for fine adjustments through the handle and can easily produce complex movements.

[0191] Meanwhile, the animation production device (100) can select and save control rig data based on handles using an animation library based on a 3D graphics engine. The animation production device (100) can select a handle of a specific part and save key data (position, rotation, etc.) of the handle in JSON format.

[0192] The animation production device (100) can perform save (Export) and apply (Import) operations based on handle data. The animation production device (100) can reconstruct animation data or replace it with new animation data.

[0193] The animation production device (100) can manage interactions between handles. The animation production device (100) can implement natural poses and movements by linking the movements of multiple handles.

[0194] For example, to describe the action of raising a hand, the animation production device (100) can sequentially perform the action of selecting a "hand handle," the action of moving the position upward, and the action of saving it as a key in a specific frame.

[0195] As another example, to describe the action of moving the foot to a target point, the animation production device (100) can sequentially perform the action of setting the movement to a specific position using a "foot handle," and the action of the control rig automatically calculating the remaining joints (e.g., legs, knees, etc.).

[0196] As such, control rig-based handles are a key tool that enables character animation work to be performed efficiently and intuitively in 3D graphics engines.

[0197] Below, we will explain the control league data handle in detail.

[0198] An animation production device (100) according to one embodiment of the present invention can perform operations such as saving and loading by analyzing control rig key data of a user-selected section using a control rig API and a Sequencer Scripting API, which are the latest animation data handle models of a 3D graphics engine. An animation production device (100) according to one embodiment of the present invention may include a key exporter module and a key importer module related to key saving and loading.

[0199] Here, control rig key data represents data that stores values ​​set at specific times (e.g., frames, etc.) in character animation and the method of calculating those values ​​(e.g., interpolation). Control rig key data can be used primarily in animation work related to sequencers of 3D graphics engines.

[0200] The components of control rig key data may include frame number, value, interpolation mode, property, and data storage method. The components of control rig key data will be described below.

[0201] First, the frame number represents the time (e.g., frame, etc.) at which a key is set on the animation timeline. For example, the frame number may include frame 0, frame 10, etc.

[0202] The Value is the value of the attribute set in the corresponding frame. For example, the Value may include position (X, Y, Z), rotation (Quaternion), scale, etc.

[0203] Interpolation Mode indicates the method of calculating values ​​between keyframes. The following modes are typically available. For example, Constant mode indicates that the value does not change until the next keyframe. Linear mode indicates that the value between two keyframes is interpolated linearly. Cubic mode indicates that the value between two keyframes is interpolated curvedly to create smooth motion.

[0204] A property represents an attribute corresponding to a specific control handle in the control rig. For example, a property can represent the root position, arm rotation, hand position, etc.

[0205] The data is stored in a structured format such as JSON and can be represented as follows. For example, if you copy the code, it can be represented as {"channelName": "Root_Ctrl.Location.X", "frameNumbers": [0, 10, 20], "values": [-273.5, -150.0, 100.0], "interpModes": ["RCIM_CONSTANT", "RCIM_LINEAR", "RCIM_CUBIC"]}.

[0206] Meanwhile, the role of the control league key data is explained as follows.

[0207] The animation production device (100) can generate animations using control rig key data. The animation production device (100) can set the movement, position, rotation, etc. of a character at a specific time using control rig key data, and generate animations based on this.

[0208] The animation production device (100) can be controlled based on time using control rig key data. The animation production device (100) can calculate data based on each keyframe using control rig key data and interpolate so that the motion changes naturally over time.

[0209] The animation production device (100) can perform data adjustment and optimization operations using control rig key data. The animation production device (100) can reduce data size and optimize performance by removing unnecessary keys or leaving only important keys using control rig key data.

[0210] I will explain data examples for actual use.

[0211] The animation production device (100) can set the X-axis position of the character as follows. The animation production device (100) can set the 0 frame: -273.5, the 10 frame: -150.0, the 20 frame: 100.0, and the interpolation mode: Linear. Also, the animation production device (100) can set the data saving method to JSON format. When copying the code, it can be represented as { "channelName": "Root_Ctrl.Location.X", "frameNumbers": [0, 10, 20], "values": [-273.5, -150.0, 100.0], "interpModes": ["RCIM_LINEAR", "RCIM_LINEAR", "RCIM_LINEAR"]}.

[0212] The animation production device (100) can efficiently control animation and cinematic work through keyframe information using control rig key data.

[0213] Meanwhile, the animation production device (100) can analyze the stored key through the key storage module. The key storage (Key Exporter) module analyzes the track of the asset bound to the sequencer and stores the key value frame by frame.

[0214] The key storage module can access "channels," which are the lowest elements constituting a sequencer track, and store the channel type, the interpolation mode of the keys existing in the channel, and the actual values ​​in JSON format.

[0215] The key storage module can store data after performing key reduction operations, such as recording only the minimum amount of data for static channels, considering the conciseness of key data and import performance.

[0216] Here, regarding tracks, in 3D graphics engines, a track is a concept used in a sequencer and refers to a data layer on a timeline that controls and animates the attributes (e.g., position, rotation, scale, etc.) or actions (e.g., events, sounds, etc.) of a specific object over time.

[0217] The components of a track may include channels and keys.

[0218] A channel is a sub-element of a track that stores specific data (frame-by-frame values, interpolation methods, etc.). For example, a position track may include channels corresponding to X, Y, and Z coordinates, respectively.

[0219] A Key is a value defined at a specific time (e.g., a frame) in a track. The track can create an animation based on the values ​​of these Keys. For example, an animation creation device (100) can create an animation by interpolating between two Keys when X=0 at frame 0 and X=100 at frame 10.

[0220] In this way, the control rig data handle can represent animation data handling operations in a 3D graphics engine. This is because animation data in a 3D graphics engine is control rig data. The animation production device (100) can perform storage and reuse functions by extending such storage and application operations from an animation library. This can primarily highlight efficiency in collaboration. There is a high probability of human error occurring while the user directly copies keys in the sequencer of a 3D graphics engine, and there are many commands that the user must input. The animation production device (100) can reduce such human errors and reduce user input.

[0221] FIG. 12 is a flowchart of the process of saving animation items of a 3D graphics engine-based animation library in an animation production method according to one embodiment of the present invention.

[0222] In step S311, the animation production device (100) inputs a screen shot into the animation library (210) in response to a user request.

[0223] In step S312, the animation production device (100) requests shot rendering from the animation library (210) via the sequencer API (230).

[0224] In step S313, the animation production device (100) receives a thumbnail / GIF file from the sequencer API (230) into the animation library (210).

[0225] In step S314, the animation production device (100) is requested to perform an animation saving operation.

[0226] In step S315, the animation production device (100) requests key analysis from the animation library (210) via the control rig API (220).

[0227] In step S316, the animation production device (100) receives key analysis results from the animation library (210) from the control rig API (220).

[0228] In step S317, the animation production device (100) performs static key filtering and reduction operations in the animation library (210).

[0229] In step S318, the animation production device (100) requests key storage from the animation library (210) to the key storage (Exporter) module.

[0230] In step S318, the animation production device (100) stores the key in JSON format in the key storage (Exporter) module.

[0231] In step S320, the animation production device (100) receives the key storage result in the animation library (210) from the key storage (Exporter) module (240).

[0232] In step S321, the animation production device (100) creates an item using the key storage result.

[0233] In step S322, the animation production device (100) records the generated items, etc., in the database (250).

[0234] In step S323, the animation production device (100) receives a success result for an item record from the database (250).

[0235] In step S324, the animation production device (100) displays items recorded in the database (250) to the user.

[0236] FIG. 13 is a diagram showing the selection of targets applied in different panels in an animation production method according to an embodiment of the present invention.

[0237] The animation production device (100) can analyze the stored key data through the Key Exporter module and reconstruct the key in the sequencer through the Key Importer module. The animation production device (100) can increase convenience by supporting selection methods in various panels, such as the Outliner, Viewport, and Sequencer, for selecting a target for key application.

[0238] The animation production device (100) can provide an outliner, a viewport, a sequencer, etc., as shown in FIG. 13.

[0239] The animation production device (100) can hierarchically manage and select actors included in the outliner level.

[0240] The animation production device (100) can provide editing of levels and objects and real-time rendering in a three-dimensional workspace through a viewport.

[0241] The animation production device (100) can provide a window for timeline tools for animation and cinematic production through a sequencer.

[0242] FIG. 14 is a flowchart of the operation of a key application module in an animation production method according to one embodiment of the present invention.

[0243] In step S411, an animation production device (100) according to one embodiment of the present invention inputs animation data into an animation library (210) in response to a user request.

[0244] In step S412, the animation production device (100) requests the loading of item information from the animation library (210) to the database (250).

[0245] In step S413, the animation production device (100) transmits item information from the database (250) to the Key Importer module (260).

[0246] In step S414, the animation production device (100) loads an animation key from the Key Importer module (260).

[0247] In step S415, the animation production device (100) applies a key to the animation library (210) from the Key Importer module (260).

[0248] In step S416, the animation production device (100) requests a key setting from the animation library (210) via the sequencer API (230).

[0249] In step S417, the animation production device (100) can provide the set key to the user.

[0250] In this way, the animation production device (100) can interpret the keys of the control rig of the 3D graphics engine and perform functions (data handles) such as saving operations and applying operations through the key saving (Exporter) module (240) and the key applying (Importer) module (260). Here, when the animation production device (100) applies the applied operation, that is, when the key applying (Importer) module (260) applies the stored keys, it can select patterns such as <overwriting>, <inserting between existing keys>, etc. That is, <various animation key application patterns> can be included in the key applying (Key Importer) module of the <control rig data handle>.

[0251] FIG. 15 is a diagram illustrating the operation of storing and applying control rig keys in an animation library (210) in an animation production method according to one embodiment of the present invention.

[0252] As shown in FIG. 15, the Control Rig Anim Key is stored in the animation library (210).

[0253] Then, the Key Exporter module (240) receives animation items from the animation library (210) and stores the animation items in the database (250) in JSON format.

[0254] The Key Importer module (260) applies control rig keys associated with animation items from the animation library (210) to the control rig through a key import operation.

[0255] FIG. 16 is a drawing showing how a saved pose is mixed with a basic pose at a gradual intensity ratio in an animation production method according to one embodiment of the present invention.

[0256] As illustrated in FIG. 16, an animation production device (100) according to one embodiment of the present invention can perform a pose blend operation.

[0257] As an example, the animation production device (100) can mix a new pose with an existing pose by a value selected by the user from a range of 1 to 100 percent.

[0258] Here, the value selected by the user can be designed to be registered in the application session as soon as the item is selected, and to be released from the session when the item is left.

[0259] By doing so, the animation production device (100) can quickly support the user in starting key animation work by testing the intensity of the pose to be applied.

[0260] FIG. 17 is a diagram illustrating the operation of supporting application patterns of various animation keys in an animation production method according to an embodiment of the present invention.

[0261] As illustrated in FIG. 17, an animation production device (100) according to one embodiment of the present invention can provide a user with various application patterns of animation keys. The animation production device (100) can support various application patterns when recalling saved keys according to the preference of an animator, that is, a user.

[0262] For example, the animation production device (100) can provide the user with various patterns such as a merge operation, a replace operation, a replace all operation, and an insert operation.

[0263] To explain the merge operation, when a new key is imported, the animation production device (100) performs an overwrite operation if the key already exists in the frame of the section selected by the user. On the other hand, the animation production device (100) can input a value if the key does not exist in the frame of the section selected by the user.

[0264] To explain the replace operation, the animation production device (100) can replace only the frames of the section selected by the user with a new key.

[0265] To explain the Replace All operation, the animation production device (100) can replace the keys of the entire frame section with the newly applied keys.

[0266] To explain the insert operation, the animation production device (100) can push back the key of the section selected by the user and insert a newly applied key.

[0267] FIGS. 18 and 19 are drawings showing the structure of a database that establishes relationships to a planar item model in an animation production device according to an embodiment of the present invention.

[0268] An animation production device (100) according to one embodiment of the present invention may include a flat file system database.

[0269] In order to faithfully perform the animation library function in an animation production method according to one embodiment of the present invention, a Model-View-Controller (MVC) architecture pattern may be used. In an animation production device (100), the database construction to be a model at runtime may be operated by flattening actual item data stored in a tree structure in a file system into a one-dimensional JSON file.

[0270] Here, the reason the file system itself is not databased when the animation library starts is that if the library root folder and its subfolders were searched within the file system to display to the user, it would take too long for items to be actually drawn and shown to the user. Due to its nature, the file system tree structure consists of parent-child relationships.

[0271] The animation production device (100) specifies the relationship for each item in the planar model so that it can take on a tree structure at runtime.

[0272] Figures 18 and 19 show a flat file system database constructed in JSON format and an item Entity Relationship Diagram of each item in the modeled database.

[0273] The flat file system database forms Parent FolderItems and Child FolderItems, as well as AnimItems and PoseItems.

[0274] In the parent structure, the Parent FolderItem is formed as a superclass.

[0275] In the substructure, the Child FolderItem is formed as a subclass connected to the Parent FolderItem through a parent-child folder relationship.

[0276] AnimItem and PoseItem are formed as subclasses of the child folder item.

[0277] All classes can share fields such as category, name, modification, folder, type, and class.

[0278] The animation production device (100) can systematically manage animation or pose-related data through this structure.

[0279] FIG. 20 is a diagram showing another example structure of a database that establishes a relationship to a flat item model in an animation production device according to one embodiment of the present invention.

[0280] To explain an example of a database in which relationships are established in the flat item model illustrated in Fig. 20, "Run" and "Smile" subfolders are formed inside the "GoodHeart" folder in the folder hierarchy, and the "Motion" folder can be formed as a top-level folder like "GoodHeart".

[0281] Each folder's attributes may include "category": specifying the folder's attributes ("library" or "GoodHeart"), "name": folder name ("GoodHeart", "Run", "Smile", "Motion"), "modified": last modified timestamp, "path": relative path to the folder, "folder": parent folder information, "type": displayed as "Folder", "movie": currently set to null, and __class__: "FolderItem" (a class representing a folder item in the database).

[0282] Here, each folder maintains a relationship with its parent folder through the "folder" attribute and can track paths between folders using the "path" attribute. It has a database structure where the hierarchy is set up in a manner such as "GoodHeart" → "Run", "Smile".

[0283] In this way, the animation production device (100) can build a flat model that operates in a file system and operate it by creating a database.

[0284] Here, the animation production device (100) can manage the database-based model at runtime by specifying relationships for each item attribute to represent a file system-specific tree structure.

[0285] A flat file system database is suitable for nested folder tree formats such as folder-folder-folder-item and can be formed to respond to the addition, modification, or deletion of items.

[0286] FIG. 21 is a diagram showing an example of specifying an FFmpeg executable file in the environment settings of an animation production device according to an embodiment of the present invention and an example of a database reconstruction function.

[0287] As illustrated in FIG. 21, an animation production device (100) according to one embodiment of the present invention can provide a database rebuild function to the user.

[0288] When it is difficult to build a model from a database due to a record error in the file system database, the animation production device (100) can provide the user with the function of rebuilding the database from items stored in the actual file system.

[0289] Meanwhile, the animation production device (100) can provide the user with various patterns of previews. The animation production device (100) can support two methods for an item: video preview and thumbnail preview.

[0290] Here, to provide a video preview, the animation production device (100) can render a section selected by the user during key export, and then convert it into a GIF image through an FFmpeg executable specified in the environment settings to create a thumbnail.

[0291] The animation production device (100) can provide an intuitive UX to the user. The animation production device (100) can enhance intuitiveness by allowing the user to control item size and item spacing using a combination of a mouse and a keyboard.

[0292] FIGS. 22 and 23 are drawings illustrating an example of an item information indexing process using multi-threading in an animation production method according to an embodiment of the present invention.

[0293] Figure 22 illustrates an item display process through a relatively fast “loading” process, and Figure 23 illustrates an item indexing process by a user while thumbnail loading is performed in multi-threaded mode.

[0294] An animation production device (100) according to one embodiment of the present invention uses multi-threading while expressing item information, so that the user's desired input is not interfered with even during the process of indexing item information.

[0295] The existence of the item itself is recorded in db.json, so the initial loading of the item can be done very quickly. The animation production device (100) can load the item's thumbnail image using multi-threading and display it on the item first. Here, if the item's thumbnail is to be loaded at startup, the startup time of the animation library may take that long. Therefore, the animation production device (100) can support the user to access the desired item even while the thumbnail is being loaded by proceeding with thumbnail loading later using multi-threading after undergoing a relatively fast “loading” process. The animation production device (100) can also retrieve thumbnail information as quickly as possible by operating multiple threads. The thumbnail information display can allow the user to estimate the completion time through a progress indicator.
