[0042] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.
[0043] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0044] The object rendering method, apparatus, computer device, and readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.
[0045] The present application embodiment provides an object rendering method, such as Figure 1 As shown, the method includes:
[0046] Step 101, obtaining the position of the virtual character on the virtual terrain in the current frame, and calculating UV information of the contact position between the virtual character and the virtual terrain according to the position;
[0047] Step 102, sampling the current moving path pattern of the virtual character in the rendering texture cache based on the UV information, the rendering texture cache is used to superimpose the path pattern of the virtual character in each frame, and the current moving path pattern is the superposition of the path pattern of the current frame and the path pattern of the frame before the current frame;
[0048] Step 103, obtaining a transition parameter, where the transition parameter is related to the moving time of the virtual character on the virtual terrain;
[0049] Step 104: Use the current moving path pattern as a mask object and render the mask object according to transition parameters, wherein the transition parameters are used to control the gradual luminescence effect of the mask object over the moving time.
[0050] In this embodiment, when the virtual character moves on the virtual terrain, multiple frames of images are generated. The position of the virtual character on the virtual terrain is determined in the current frame image, and the UV information of the contact position between the virtual character and the virtual terrain is calculated based on the position of the virtual character, that is, the UV information of the virtual character's feet.
[0051] Furthermore, the current moving path pattern of the virtual character is sampled in a render texture (RT) cache according to the UV information. That is, the render texture cache pre-stores a moving path pattern superimposed with the path pattern of the virtual character in each frame image. For example, the current moving path pattern of the current frame is obtained by superimposing the path pattern of the current frame with the path patterns of all frames before the current frame, and there is a corresponding relationship between one moving path pattern and one UV information, so that the current moving path pattern corresponding to the UV information can be obtained from multiple moving path patterns stored in the render texture cache.
[0052] Furthermore, a transition parameter related to the moving time of the virtual character on the virtual terrain is obtained, and the transition parameter can control the luminous gradient effect of the moving path pattern of the virtual character during subsequent rendering.
[0053] The current moving path pattern is used as a mask object (also known as a path mask), and the mask object is rendered according to the transition parameters, so that the mask object can achieve the effect of luminescence and gradual change over time. For example, in the plant material, the current moving path pattern is used as a mask object, and the brightness of the mask object is gradually increased over time, so that the mask object gradually turns white. Figure 3 As shown, the rendering effect of the plant's glow gradually disappearing when the character approaches is achieved.
[0054] It should be noted that the order of step 102 and step 103 is not specifically limited, and the transition parameters may be obtained first and then the current moving path pattern of the virtual character, or both may be obtained at the same time.
[0055] In the embodiment of the present application, during the movement of the virtual character, the movement path pattern sampled in the rendering texture cache is used as a mask object, and the mask object is gradually changed over the movement time according to the transition parameters, thereby achieving the effect of leaving glow and halo residues as the character passes by, saving running rendering batches and enhancing the player's sense of interaction and visual effects.
[0056] As a refinement and extension of the above embodiment, the embodiment of the present invention provides another object rendering method, such as Figure 2 As shown, the method includes:
[0057] Step 201, determining a rendering texture cache according to the terrain size of the virtual terrain;
[0058] Step 202, superimposing the walking path patterns of the virtual character in each frame to generate multiple moving path patterns, and storing the multiple moving path patterns in the rendering texture cache;
[0059] Step 203, obtaining the position of the virtual character on the virtual terrain in the current frame, and calculating UV information of the contact position between the virtual character and the virtual terrain according to the position;
[0060] Step 204, sampling the current moving path pattern of the virtual character in the rendering texture cache based on the UV information, the rendering texture cache is used to superimpose the path pattern of the virtual character in each frame, and the current moving path pattern is the superposition of the path pattern of the current frame and the path pattern of the frame before the current frame;
[0061] Step 205, obtaining a transition parameter, where the transition parameter is related to the moving time of the virtual character on the virtual terrain;
[0062] Step 206: Use the current moving path pattern as a mask object and render the mask object according to transition parameters, wherein the transition parameters are used to control the gradual luminescence effect of the mask object over the moving time.
[0063] Among them, step 203 to step 206 are the same as or similar to step 101 to step 104 in the above embodiment, and are not described again here.
[0064] In this embodiment, a rendering texture cache is applied according to the terrain size of the virtual terrain. For example, if the terrain size of the virtual terrain is 512, a rendering texture cache of 512 is applied. By applying for a rendering texture cache of a suitable size according to the terrain size ratio of the virtual terrain, the subsequent rendering effect is ensured while avoiding memory occupation.
[0065] Furthermore, multiple movement path patterns of the virtual character are stored in the rendering texture cache. Specifically, the walking path pattern of the virtual character in each frame is superimposed with the walking path pattern of the virtual character in the previous frame to obtain multiple different movement path patterns, one frame of image corresponds to one movement path pattern, and the movement path pattern is stored in the rendering texture cache.
[0066] In an embodiment of the present application, the path patterns of the characters walking in all frames are superimposed in advance to obtain a moving path pattern corresponding to each frame image, and the moving path pattern is stored in a rendering texture cache. In subsequent rendering, the moving path pattern is used as a mask to achieve a luminous effect.
[0067] In one embodiment of the present application, a method for determining a path pattern of any frame includes:
[0068] Calculate UV information of a contact position between the virtual character and the virtual terrain according to the terrain size of the virtual terrain and the character world space position of the virtual character;
[0069] The pattern texture of the preset luminous pattern is sampled through UV information to obtain the path pattern of the virtual character walking in any frame.
[0070] In one embodiment of the present application, the walking path patterns of the virtual characters in all frames are superimposed to generate a moving path pattern, including:
[0071] The path pattern of any frame is copied to the rendering texture cache, and the path pattern is superimposed with the path patterns of all frames before any frame to generate the moving path pattern of any frame.
[0072] In this embodiment, the path pattern of each frame is obtained by sampling the pattern texture according to the UV information of the contact position between the virtual character and the virtual terrain.
[0073] Specifically, for any frame of image, firstly, the world coordinate ratio and the character rotation angle are calculated according to the data such as the character world space position of the virtual character and the terrain size of the virtual terrain, and then the UV information of the contact position between the virtual character and the virtual terrain is calculated according to the world coordinate ratio and the character rotation angle. For example, the coordinate XZ of the character world space position of the virtual character is divided by the terrain size, and the coordinate Y of the character world space position of the virtual character is divided by 180 and multiplied by 3.14. Based on the obtained two world coordinate ratio data, the UV information is obtained by the following calculation:
[0074] UV_rotated.x=cos(theta)×UV.x+sin(theta)×UV.y;
[0075] UV_rotated.y=-sin(theta)×UV.x+cos(theta)×UV.y;
[0076] Among them, (UV.x, UV.y) is the original world coordinate scale data, (UV_rotated.x, UV_rotated.y) is the UV information, and theta is the character rotation angle.
[0077] Then, a pattern texture of a preset luminous pattern is sampled through UV information sampling as the path pattern for the virtual character to walk in the frame.
[0078] Through the above method, a corresponding path pattern can be obtained for each frame. Furthermore, the path pattern is stored in the rendering texture cache, and the path patterns corresponding to different frames are stored in the rendering texture cache. Subsequently, the path pattern corresponding to a frame image and the path pattern corresponding to the frame before the frame image are superimposed to obtain the moving path pattern of the frame. For example, the path patterns from the 1st frame to the i-th frame are superimposed to obtain the moving path pattern of the i-th frame image; the path patterns from the 1st frame to the i+1th frame are superimposed to obtain the moving path pattern of the i+1th frame image. And the multiple moving path patterns obtained are stored in the rendering texture cache for subsequent rendering.
[0079] In an embodiment of the present application, a moving path pattern that is subsequently used as a mask object is obtained by acquiring a path pattern of a virtual character's walking and superimposing the path patterns, thereby achieving an effect of gradually disappearing light based on the mask object when the character moves.
[0080] In one embodiment of the present application, the method further includes:
[0081] The moving path pattern in the rendering texture cache is downsampled to achieve edge blurring of the moving path pattern.
[0082] In this embodiment, after the moving path pattern is generated and stored in the rendering texture cache, the moving path pattern in the rendering texture cache is downsampled to achieve edge blurring of the moving path pattern. For example, the resolution of the moving path pattern is divided by a coefficient to achieve blurring of the moving path pattern, thereby avoiding abrupt mask edges and improving visual effects.
[0083] In one embodiment of the present application, the method further includes:
[0084] During the movement of the avatar, the transition parameter is calculated according to the movement time of the avatar.
[0085] In this embodiment, a value that gradually changes over time, namely a transition parameter, is calculated according to the movement of the virtual character and the movement time of the virtual character. The transition parameter is used in the subsequent production of the gradient of the mask object, thereby achieving a luminous gradient effect of the moving path.
[0086] In one embodiment of the present application, rendering the luminous effect of the mask object in combination with the transition parameters includes:
[0087] According to the transition parameters, the brightness value of the mask object as the light and dark changes over the moving time is calculated;
[0088] Renders a glow gradient effect of the masked object based on the brightness value.
[0089] In this embodiment, as the virtual character moves over time, the brightness value of the mask object is gradually changed using transition parameters to achieve the effect of the light gradually disappearing. For example, on a white virtual terrain image, there is a black moving path pattern, and the brightness of the moving path pattern is gradually increased, and finally the moving path pattern becomes completely white, making the black path disappear.
[0090] Through the above method, the luminous and halo residual effects of the moving path of the virtual character are achieved.
[0091] In summary, in the embodiment of the present application, a rendering texture cache is determined according to the size of the terrain, and the rendering texture cache continuously superimposes the path pattern of the virtual character walking in each frame to obtain multiple moving path patterns, and the moving path pattern in the rendering texture cache is downsampled to achieve edge blur. The UV information of the contact position between the virtual character and the virtual terrain is calculated according to the position of the virtual character, and the moving path pattern in the rendering texture cache is sampled by UV information and used as a mask in the plant material to achieve a luminous effect, and according to the transition parameters, the mask gradually disappears as the virtual character moves over time.
[0092] Furthermore, as a specific implementation of the above object rendering method, an embodiment of the present application provides an object rendering device. Figure 4 As shown, the object rendering device 400 includes: a first information acquisition module 401 , a second information acquisition module 402 and a rendering module 403 .
[0093] The first information acquisition module 401 is used to acquire the position of the virtual character on the virtual terrain in the current frame, and calculate the UV information of the contact position between the virtual character and the virtual terrain according to the position;
[0094] The second information acquisition module 402 is used to sample the current moving path pattern of the virtual character in the rendering texture cache based on the UV information, the rendering texture cache is used to superimpose the path pattern of the virtual character in each frame, and the current moving path pattern is the superposition of the path pattern of the current frame and the path pattern of the frame before the current frame; and obtain transition parameters, which are related to the moving time of the virtual character on the virtual terrain;
[0095] The rendering module 403 is used to use the current moving path pattern as a mask object and render the mask object according to transition parameters, wherein the transition parameters are used to control the luminous gradient effect of the mask object over the moving time.
[0096] In this embodiment, when the virtual character moves on the virtual terrain, multiple frames of images are generated. The position of the virtual character on the virtual terrain is determined in the current frame image, and the UV information of the contact position between the virtual character and the virtual terrain is calculated according to the position of the virtual character, that is, the UV information of the foot of the virtual character. Further, the current moving path pattern of the virtual character is sampled in the rendering texture cache according to the UV information, that is, the rendering texture cache pre-stores the moving path pattern superimposed with the path pattern of the virtual character walking in each frame image, and there is a corresponding relationship between a moving path pattern and a UV information, so that the current moving path pattern corresponding to the UV information can be obtained from the multiple moving path patterns stored in the rendering texture cache. And, the transition parameters related to the moving time of the virtual character on the virtual terrain are obtained, and the transition parameters can control the luminous gradient effect of the moving path pattern of the virtual character when rendering is performed later. When rendering, the current moving path pattern is used as a mask object, and the mask object is rendered according to the transition parameters, so that the mask object can achieve the effect of luminescence and gradient change over time.
[0097] In the embodiment of the present application, during the movement of the virtual character, the movement path pattern sampled in the rendering texture cache is used as a mask object, and the mask object is gradually changed over the movement time according to the transition parameters, thereby achieving the effect of leaving glow and halo residues as the character passes by, saving running rendering batches and enhancing the player's sense of interaction and visual effects.
