Description

Technical Field

[0001] This invention relates to the field of computer graphics processing technology, and in particular to a display control method and a display control device for games. Background Technology

[0002] In game development, it is sometimes necessary to create an effect generated by physical collisions that conforms to the rules of physical collisions, looks realistic and attractive, and has a low performance consumption within an acceptable range. For example, creating an effect where, in soft terrains such as snow, desert, or mud, people, animals, or vehicles leave pits or footprints when they pass through. This is a challenge in game development.

[0003] Currently, most games achieve the desired terrain depression effect by dynamically adding decals to the surface of the terrain, adding a decal for each collision; or by enabling double-sided rendering of the terrain, adding a camera to capture textures on the reverse side of the terrain, and then blending the captured textures with the terrain to produce the corresponding terrain depression effect.

[0004] However, the above methods for achieving terrain depression effects have the following drawbacks: because the dynamic decal addition method requires generating a decal object for each terrain depression effect (such as footprints), and the dual-sided rendering method for terrain requires enabling custom depth rendering for each character, all of these will cause the game's performance consumption to increase continuously. Summary of the Invention

[0005] Given that the dynamic decal application method requires generating a decal object for each terrain depression effect, and the dual-sided terrain rendering method requires custom depth rendering for each character, which leads to a continuous increase in game performance consumption, this invention proposes an embodiment to provide a display control method and corresponding display control device in a game that overcomes or at least partially solves the above problems.

[0008] Based on the height of the terrain and the location of the virtual object, a mesh model is rendered on the terrain, and a camera is deployed below the mesh model;

[0009] The first texture mask image is obtained by capturing the virtual object and the mesh model with the camera.

[0010] The terrain is rendered in the game scene according to the first texture mask map to present the terrain depression effect caused by the virtual object on the terrain.

[0012] Obtain the second texture mask image captured from the game scene of the previous frame;

[0013] The first texture mask image and the second texture mask image are merged to obtain the target mask image;

[0014] The terrain is rendered in the game scene according to the target mask map to present the effect of terrain depression retention.

[0015] Optionally, obtaining the height of the terrain in the game scene of the current frame includes:

[0016] The height of the terrain is obtained by rendering the height channel of the terrain in the game scene of the current frame using a virtual texture component.

[0017] Optionally, rendering a mesh model on the terrain based on the terrain's height and the virtual object's location includes:

[0018] The height of the terrain is increased by a preset value to obtain the offset height;

[0019] A mesh model is rendered on the terrain based on the offset height and the location of the virtual object.

[0020] Optionally, after the step of rendering a mesh model on the terrain based on the terrain's height and the location of the virtual object, the method further includes:

[0021] Control the mesh model to move along with the virtual object.

[0022] Optionally, controlling the mesh model to move with the virtual object includes:

[0023] When the virtual object moves in the game scene, the position offset of the virtual object is determined;

[0024] The mesh model is controlled to move along with the virtual object according to the stated position offset.

[0025] Optionally, after the step of deploying a camera below the mesh model, the method further includes:

[0026] The objects captured by the camera are set to the virtual object and the mesh model.

[0027] Optionally, the terrain includes one or more of the following: snow, desert, and wetland.

[0028] This invention also discloses a display control device for games, comprising:

[0029] The terrain height acquisition module is used to obtain the height of the terrain and the location of virtual objects in the game scene of the current frame;

[0030] A camera deployment module is used to render a mesh model on the terrain based on the height of the terrain and the location of the virtual object, and to deploy a camera below the mesh model.

[0031] A texture mask image capturing module is used to capture images of the virtual object and the mesh model through the camera to obtain a first texture mask image;

[0032] The terrain rendering module is used to render the terrain in the game scene according to the first texture mask map, so as to present the terrain depression effect caused by the virtual object on the terrain.

[0036] The embodiments of the present invention have the following advantages:

[0037] In this embodiment of the invention, a camera is deployed using a mesh model to capture virtual objects. This mesh model can occlude unwanted textures within the virtual objects, allowing only the necessary textures to be captured. For example, if only the texture of the feet needs to be captured, the mesh model occludes the textures of the virtual objects other than the feet, eliminating the need for additional culling of the camera's captured content and saving rendering resources. Furthermore, by directly obtaining the terrain height for rendering, there is no need to generate decal objects or enable custom depth rendering for each virtual object, thus improving rendering efficiency. Rendering costs are not increased by collisions or the number of virtual objects. Moreover, the terrain depression effect produced by this method can be as deep as desired, with excellent physical collision effects, enhancing the game's visual appeal. Attached Figure Description

[0047] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0048] In existing technologies, decals are dynamically added to the surface of the terrain, with one decal added for each collision to achieve the desired terrain effect; alternatively, double-sided rendering is enabled for the terrain, with a camera capturing textures on the reverse side of the terrain and then blending the captured textures with the terrain to produce the corresponding terrain effect. However, for the dynamic decal addition method, each terrain effect (such as footprints) requires the generation of a new decal object, causing a continuous increase in game performance; the shape of each terrain effect (such as footprints) is consistent, requiring the creation of several different types of textures randomly; the pits created by the decals on the terrain are not deep enough or realistic enough; and the physicality is not strong. For the double-sided rendering method, each character needs to enable custom depth rendering, which also causes a continuous increase in game performance; because of the added camera, large terrains require an additional culling calculation.

[0049] To address the aforementioned technical problems, this invention provides a display control method for games. This method involves obtaining the height of the terrain and the position of a virtual object in the game scene of the current frame; rendering a mesh model on the terrain based on the terrain height and the virtual object's position; and deploying a camera below the mesh model; capturing images of the virtual object and the mesh model using the camera to obtain a first texture mask image; and rendering the terrain in the game scene based on the first texture mask image to present the terrain depression effect caused by the virtual object moving on the terrain. By utilizing a mesh model to deploy a camera to capture virtual objects, the mesh model can mask unwanted textures within the virtual object, achieving the goal of capturing only the necessary textures. For example, if only the texture of the feet needs to be captured, the mesh model can mask the textures of the virtual object other than the feet, thus eliminating the need for additional culling of the camera's captured content and saving rendering resources. Moreover, by setting the camera directly according to the height of the terrain to capture texture maps for rendering, there is no need to generate decal objects or enable custom depth rendering for each virtual object that needs to be rendered, thereby improving rendering efficiency. The rendering cost will not increase performance overhead due to collisions or the increase of virtual objects. In addition, the terrain depression effect produced by this method can be as deep as desired, and the physical collision effect is very good, enhancing the game's performance.

[0050] Reference Figure 1 The diagram illustrates a flowchart of an embodiment of a display control method in a game provided by the present invention, which may specifically include the following steps:

[0051] Step 101: Obtain the height of the terrain and the location of the virtual object in the game scene of the current frame;

[0052] In this embodiment of the invention, the height of the terrain and the location of the virtual object in the game scene of the current frame can be obtained by calling the interface provided by the game engine. The virtual object can be a movable virtual unit in the game scene, such as a character, animal, or vehicle.

[0053] In this embodiment of the invention, the terrain may include any one or more of the following: snow, desert and wetland. These terrains are relatively soft and will cause the terrain to sink when virtual objects pass through them. For example, when a person passes through the snow, they will leave footprints or footprints, and when a vehicle passes through the snow, it will leave tire tracks.

[0054] In a preferred embodiment of the present invention, obtaining the height of the terrain in the game scene of the current frame includes:

[0055] The height of the terrain is obtained by rendering the height channel of the terrain in the game scene of the current frame using a virtual texture component.

[0056] The virtual texture component can render the required channels on the terrain material and save them to the hard drive via virtual data output. In this embodiment of the invention, the height value of the terrain is mainly needed. Therefore, by setting basic parameters such as rendering type, rendering size, and rendering texture position, the height channel of the terrain in the game scene of the current frame is used to obtain the height of the terrain.

[0057] Step 102: Based on the height of the terrain and the location of the virtual object, render a mesh model on the terrain and deploy a camera below the mesh model;

[0058] In this embodiment of the invention, a mesh model is rendered on the terrain based on its height and the location of the virtual object, and a camera is deployed below the mesh model. The mesh model can be square, but other shapes such as rhombuses or circles can be used as needed; this embodiment does not impose any limitations on this. It should be noted that the rendered mesh model in this embodiment may not be displayed in the game interface; that is, the mesh model is imperceptible to the user to avoid affecting the display effect of the game interface.

[0059] As an example, such as Figure 2As shown, the mesh model is square. A camera is deployed below the mesh model so that the camera can capture images of the mesh model. At the same time, if a virtual object is located below the mesh model, the virtual object can also be captured by the camera.

[0060] In a preferred embodiment of the present invention, after step 102, the following sub-steps may be included:

[0061] The objects captured by the camera are set to the virtual object and the mesh model.

[0062] In this embodiment of the invention, the objects captured by the camera can be set to virtual objects and mesh models, that is, other models on the terrain are not rendered, thereby reducing the number of models that need to be rendered. In a specific implementation, in the settings interface, you can select "Use only list" in the primitive rendering unit mode, and then add the virtual objects and mesh models that need to be rendered to the "only displayed actor values". For example, you can set the array elements that the camera can capture to include "BP_VVR_Footprint" and "BP_Player_01_MVR", where "BP_VVR_Footprint" corresponds to the mesh model and "BP_Player_01_MVR" corresponds to the virtual object.

[0063] Step 103: Capture the virtual object and the mesh model using the camera to obtain a first texture mask image;

[0064] In this embodiment of the invention, a first texture mask image can be obtained by capturing images of a virtual object and a mesh model using a camera. In one example, the mesh model is captured as white and the virtual object as black, thus forming a black-and-white mask image. This allows the texture of the virtual object to be stored as a single-channel texture, reducing the memory consumed in storing the texture. Of course, the first texture mask image can also be stored as a multi-channel texture image as needed, and this embodiment of the invention does not impose any limitations on this.

[0065] Specifically, during filming, the mesh model can mask unwanted textures in the virtual object, allowing only the necessary textures to be captured. For example, if only the texture of the feet needs to be captured, the mesh model can mask the textures of other parts of the virtual object besides the feet, such as the trouser legs, body, arms, etc., thus eliminating the need for additional culling of the content captured by the camera.

[0066] Step 104: Render the terrain in the game scene according to the first texture mask map to present the terrain depression effect caused by the virtual object on the terrain.

[0067] In this embodiment of the invention, after capturing the first texture mask image, the terrain can be rendered in the game scene based on the first texture mask image to present the terrain depression effect caused by the virtual object on the terrain. Specifically, during rendering, the white areas in the first texture mask image are rendered as the terrain texture, and the black areas are rendered as the texture of the virtual object, such as the texture of a character's feet.

[0068] like Figure 3 As shown, in a preferred embodiment of the present invention, the step of rendering the terrain in the game scene according to the first texture mask map to present the terrain depression effect caused by the virtual object on the terrain may specifically include the following sub-steps:

[0069] Sub-step S11: Obtain the second texture mask image captured from the game scene in the previous frame;

[0070] Sub-step S12: Merge the first texture mask image and the second texture mask image to obtain the target mask image;

[0071] Sub-step S13: Render the terrain in the game scene according to the target mask map to present the effect of terrain depression retention.

[0072] In the real world, when a person or vehicle passes over soft terrain, the resulting depressions don't immediately disappear but remain for a certain period. Since games refresh the rendered terrain depressions (such as footprints) in each frame of the game scene, this embodiment of the invention, in order to simulate the terrain depressions left by virtual objects passing over the terrain in the previous frame and further enhance the game's realism, acquires and merges the texture mask images captured in the current and previous frames of the game scene, and then renders according to the merged texture mask image.

[0073] Specifically, a second texture mask is obtained by capturing the game scene of the previous frame. The game scene of the previous frame refers to the game scene in the frame before the game scene of the current frame. The second texture mask can be the merged mask used when rendering the game scene of the previous frame.

[0074] In this embodiment of the invention, after obtaining the second texture mask image, a target mask image is further obtained by merging the first and second texture mask images. The terrain is then rendered in the game scene based on the target mask image to achieve a terrain depression effect. Figure 4 A schematic diagram illustrating the preservation of terrain depression effects is shown, in which... Figure 4 The virtual object is a person, and the terrain is a desert. When the person passes through the desert, a series of footprints will be left behind the person.

[0075] In a preferred embodiment of the present invention, rendering a mesh model on the terrain based on the height of the terrain and the location of the virtual object includes:

[0076] The height of the terrain is increased by a preset value to obtain the offset height; based on the offset height and the location of the virtual object, a mesh model is rendered on the terrain.

[0077] The preset value can be a pre-set height value used to ensure that the rendered mesh model forms a height difference with the terrain, so that the mesh model can be attached to the terrain. For example, the preset value is 10, etc. This embodiment of the invention does not limit this.

[0078] In this embodiment of the invention, the height of the terrain is increased by a preset value to obtain the offset height. Then, based on the offset height and the position of the virtual object, a mesh model is rendered on the terrain. Consequently, the camera rendered below the mesh model in subsequent steps also forms a height difference with the ground, appearing to float above the terrain. Figure 5 As shown, the virtual object and the mesh model will overlap, allowing the camera to capture the texture of the virtual object that overlaps under the mesh model. For example, a person's foot will overlap under the mesh model, allowing the camera to capture the texture of the person's foot and use the foot texture to create a footprint effect.

[0079] In a preferred embodiment of the present invention, after the step of rendering a mesh model on the terrain based on the height of the terrain and the location of the virtual object, the method further includes:

[0080] Control the mesh model to move along with the virtual object.

[0081] In this embodiment of the invention, after rendering the mesh model, the mesh model can be further configured to move synchronously with the virtual object, thereby ensuring that the movement of the virtual object will not be noticeable.

[0082] In a preferred embodiment of the present invention, controlling the mesh model to move with the virtual object includes:

[0083] When the virtual object moves in the game scene, the position offset of the virtual object is determined; the mesh model is controlled to move with the virtual object according to the position offset.

[0084] In this embodiment of the invention, when a virtual object moves in the game scene, its position offset is determined, and then the mesh model is controlled to move with the virtual object according to the position offset. In a specific implementation, the parameter passing function provided by the game engine (such as Unity) can be used to construct a blueprint in the game engine to pass the position offset of the virtual object. This blueprint obtains the position of the virtual object in real time for each frame, calculates the position offset between the current frame and the previous frame, and then passes the calculated position offset to the terrain material, so that the rendering on the terrain material controls the mesh model to move with the virtual object according to the position offset.

[0085] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions. However, those skilled in the art should understand that the embodiments of the present invention are not limited to the described order of actions, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously.
