Abstract
Description
Technical Field
[0001] The present invention relates to the field of animation processing technology, and in particular to a process and method for losslessly importing a three-dimensional construction simulation animation into an Unreal Engine. Background Art
[0002] Construction animation is one of the most common construction briefing methods currently used in the construction field. Its advantage is that it can be viewed on any device that can play animation, regardless of time and location. However, its disadvantages are also obvious. It requires a lot of animation production time in the early stage and post-rendering and editing, etc. Moreover, the produced animation is generally a two-dimensional effect on the playback platform, and it is impossible to truly view its actual three-dimensional spatial relationship.
[0003] Therefore, based on the convenient development and visualization of the current Unreal Engine, the construction simulation animation can be packaged into the Unreal Engine for output, and the output can be a multi-platform visual simulation animation program. The program reflects the real three-dimensional spatial relationship, and can view the details of the construction simulation briefing more intuitively.
[0004] However, Unreal Engine has low support for animation production. Therefore, if animations produced using DCC software need to be imported into Unreal Engine for production, losses often occur. The losses are often manifested as some key frames failing to be displayed. Summary of the invention
[0005] In view of this, the purpose of the present invention is to provide a process and method for losslessly importing a three-dimensional construction simulation animation into an Unreal Engine, which can process the produced animation to avoid the situation where key frames are invisible in the animation processed by the virtual engine, and the final exported animation can be displayed more intuitively.
[0006] The present invention provides a process and method for losslessly importing a three-dimensional construction simulation animation into an Unreal Engine, comprising the following steps:
[0007] Export all animation frames of the construction animation to a preset format to form a model file;

[0009] Create a new virtual level in the virtual engine, and drag the model file into the virtual level;
[0010] Opening a model file in a virtual level, and performing visibility detection on the animation frames in the model file;
[0011] When the animation frame in the model file is invisible, configuring visibility parameters of the animation frame;
[0012] After the configuration is completed, the trigger setting is played for the model file.
[0013] In one embodiment, exporting all animation frames of the construction animation into a preset format to form a model file further includes:
[0014] Produce construction animations through DDC software;
[0015] The animation frames of the construction animation are exported from the DDC software into a preset format through the Datasmith plug-in to form the model file.

[0017] Traversing the animation frames of the model file;
[0018] The visibility parameters of the animation frame configuration of the model file are detected.

[0021] Configure visibility parameters for all animation frames.
[0022] In one embodiment, when the animation frame in the model file is invisible, configuring visibility parameters for the animation frame further includes:

[0036] See also Figure 1 The present invention provides a process and method for losslessly importing a three-dimensional construction simulation animation into an Unreal Engine, comprising the following steps:
[0037] S1, export all animation frames of the construction animation into a preset format to form a model file.
[0038] It is known that the above steps may further include:
[0039] S101, create construction animation using DDC software.
[0040] It is understandable that Unreal Engine has low support for animation production, so DCC software is generally used for animation production. Unreal Engine can support files such as OBJ, FBX and .ABC formats. .OBJ does not support animation frames, so OBJ format cannot be used. ABC only supports point cache animation. There are too many steps in general construction animation. Point cache will greatly increase the performance overhead of the computer, so it is not appropriate to use ABC for construction animation. FBX is more suitable, but if FBX wants to maintain the animation relationship, it needs to import the binding relationship of the entire file. Because this binding relationship will make it impossible to make secondary modifications in Unreal Engine. Therefore, for construction simulation animation, FBX format cannot be used to import.
[0041] S102, export the animation frames of the construction animation from the DDC software to a preset format through the Datasmith plug-in to form a model file.
[0042] It can be understood that the construction animation made by the DCC software is exported as a whole using the Datasmith plug-in, and then exported to Datasmith's proprietary format. The construction animation consists of several consecutive animation frames, namely key frames. The animation models of the key frames are all manually inserted and produced, and the transition frames between the key frames can be created and added by the DCC software. Each animation frame can be marked with a timestamp.
[0043] S2 imports the model file into Unreal Engine.
[0044] It is understandable that before importing the model file, you need to enable the Datasmith plug-in function in the Unreal Engine, and then import the model file in a proprietary format into the Unreal Engine.
[0045] S3, create a new virtual level in the virtual engine and drag the model file into the virtual level.
[0046] Understandably, the visual effects and physics simulation capabilities of Virtual Levels allow film and television producers to create high-quality visual effects and sets.
[0047] S4, opening the model file in the virtual level, and performing visibility detection on the animation frames in the model file.
[0048] It is understandable that the above steps may further include:
[0049] S401, traversing the animation frames of the model file.
[0050] It can be understood that the traversal can be performed in the order of timestamps from small to large.
[0051] S402, detecting visibility parameters of the animation frame configuration of the model file.
[0052] It is known that in addition to the corresponding model parameters, the animation frames in the model file will also be configured with corresponding visibility parameters, that is, visible and invisible parameters. When imported into the virtual engine, the parameters configured in the animation frames may be lost. In many cases, the loss is due to the incompatibility of the data generated by the DCC software with the virtual engine. Therefore, some animation frames in the virtual engine will become invisible, which will be displayed as missing animation frames.
[0053] S5, when the animation frame in the model file is invisible, configure visibility parameters of the animation frame.
[0054] It is understandable that the above steps may further include:
[0055] S501, selecting all animation frames in the model file.
[0056] It can be understood that all animation frames in the model file are opened, which are referred to as key frames.
[0057] S502: Configure visibility parameters for all animation frames.
[0058] It is understandable that the visibility parameters of all key frames in the animation frame are reconfigured to achieve the processing of the animation frame. After configuration, the animation formed by the animation frame can be played normally in the Unreal Engine.
[0059] S6, after the configuration is completed, the model file playback trigger settings are performed.
[0060] It is known that the above steps may further include:
[0061] S601, open the blueprint visual programming system in the Unreal Engine;
[0062] S602, performing a play trigger setting for the animation frame after the configuration is completed.
[0063] It is understandable that the play trigger setting can be understood as a start-stop button setting, a fast-forward button setting and an angle adjustment button setting. The angle adjustment button setting can include setting the adjustment angle and the adjustment method, etc.
[0064] S7, open the packaging function module in the virtual engine; package the animation frames for the corresponding platform.
[0065] It can be understood that the corresponding platform can be a video playback platform. The video frames are encoded according to the requirements of the corresponding video playback platform. After encoding, they can be decoded and played on the corresponding video playback platform, and can be viewed interactively to achieve viewing of the animation without blind spots.
[0066] From the above description, it can be known that the process and method of losslessly importing a three-dimensional construction simulation animation into the Unreal Engine provided by the present invention can process the produced animation, thereby avoiding the situation where key frames of the animation processed by the virtual engine are invisible, and the final exported animation can be displayed more intuitively.
[0067] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
