Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1 is a flowchart of a model rendering method according to an embodiment of the present invention, where the method may be performed by a model rendering device, the device may be implemented in software and/or hardware, and the device may be configured in a computer device. As shown in fig. 1, the method specifically may include the following steps:
s110, acquiring a target object model, wherein the target object model comprises a cross insert sheet overall view model and a billboards detail model.
Preferably, the target object model may be an object model in the game world, which may be a tree model, a house model, a character model, or the like. The target object model in the embodiment comprises a cross insert profile model constructed by a cross insert method and a billboard detail model constructed by a billboard method, wherein the profile model is mainly used for showing the rough outline of an object, and the detail model is used for showing the details of the object. For example, if the target object model is a tree model, the cross-shaped insert profile model is mainly used for showing the general shape of the tree, and the detail model is used for showing the leaf and other detail parts of the tree.
For the cross insert profile model, the number of the cross inserts is not particularly required, and can be determined according to actual requirements so as to be capable of showing the profile of the object and occupy too much memory and rendering time to be optimal. For the billboard detail model, the number of billboard patches can be one or a plurality of the billboard patches, so that the detail of the object can be displayed optimally. Each billboard face may be rotated about its own center point with the face facing always towards the player.
In order to make the player feel the real state of the object similar to the natural world during the game, it is preferable that the target object model in the embodiment may be used when the game scene is that the distance between the object and the viewing angle of the player is within the preset range, and the cross insert model may be used when the game scene is that the distance between the object and the viewing angle of the player is less than the minimum boundary value of the preset range, and the billboards model may be used when the game scene is that the distance between the object and the viewing angle of the player is greater than the maximum boundary value of the preset range. In a game scenario where the distance between the object and the player's perspective is less than the minimum boundary value of the preset range, it is necessary to reveal as much specific details of the object as possible because the distance between the object and the player's perspective is relatively close, and therefore it is necessary to use an advanced detail object model. By way of example, the advanced detail object model may be an object model that is constructed using as many cross tabs as possible. In a game scene in which the distance between the object and the view angle of the player is greater than the maximum boundary value of the preset range, the object can be displayed by adopting a low-level detail object model because the distance between the object and the view angle of the player is far, and specific details of the object do not need to be displayed. By way of example, the low-level detail object model may be an object model made up of a billboard panel. It should be noted that the use scenario of the target object model is only a preferred example, and the target object model in this embodiment may be applied to a case where the game scene is that the distance between the object and the viewing angle of the player is smaller than the minimum boundary value of the preset range, and the game scene is that the distance between the object and the viewing angle of the player is greater than the maximum boundary value of the preset range.
In this embodiment, preferably, the game engine (for example, may be Unity) may obtain the target object model from the model storage database during the game loading process.
S120, determining the billboard panel position data of the billboard detail model.
Wherein the billboard patch position data may include vertex position data and center point position data for each patch. The shape of the billboard panel may be arbitrary, and may be, for example, one of a triangle, a rectangle, and a hexagon, which has three vertices when the billboard panel is a triangle, six vertices when the billboard panel is a hexagon, or the like.
In this embodiment, the center point position data in the billboards position data may be stored in an additional preset data storage space, or may be stored together with each vertex position data, and preferably, the center point position data may be stored in the vertex color data of each vertex. When rendering the billboards, it is preferable to acquire the center point position data in the preset data storage space for the case where the center point position data is stored in the additional preset data storage space, and to acquire the center point position data in the vertex color data of each vertex for the case where the center point position data is stored together with each vertex position data.
And S130, rendering and displaying the target object model based on the billboards position data.
After the position data of the billboards are obtained, the position data of the cross inserting sheets in the target object model are combined, the target object model can be rendered, and the rendered target object model picture is displayed on a corresponding display interface.
Preferably, when the billboard detail model is rendered, a vertex-by-vertex rendering mode can be adopted, namely, each time vertex position data of one vertex is determined, the billboard detail model is rendered by combining with the center point position data, so that the billboard effect is achieved.
According to the model rendering method provided by the embodiment, a target object model is obtained, wherein the target object model comprises a cross insert overall model and a billboards detail model; determining billboard panel position data of a billboard detail model; the target object model is rendered and displayed based on the billboards, and the target object model is designed and rendered and displayed by using the two methods of the cross inserting sheet and the billboards, so that the defects of long rendering time, more memory occupation, obvious inserting sheet line effect of the model, attractive appearance and the like caused by excessive use of the triangular surface of the model are overcome, the rendering pressure of a game engine is relieved, the memory occupation is reduced, and meanwhile, the display picture is more attractive.
On the basis of the above embodiments, further, before obtaining the target object model, the method further includes:
constructing an initial object model based on a cross inserting method, wherein the initial object model comprises a cross inserting profile model and a cross inserting detail model;
and replacing the cross insert detail model with the billboards detail model to obtain the target object model.
In this embodiment, the initial object model (which may also be referred to as a high-precision object model) is constructed by using the cross insert method, and after the cross insert model is constructed, the cross insert detail model may be preferably replaced by a billboard detail model. For example, one billboard panel may be used instead of the cross tab detail model, and a plurality of billboards may be used instead of the cross tab detail model.
When the initial object model is constructed, the initial object model can be constructed by utilizing a cross insert method, and then the initial object model is divided into an outer cross insert profile model and an inner cross insert detail model.
Based on the above embodiments, further, replacing the cross insert detail model with a billboards detail model includes:
and respectively replacing each cross insert in the cross insert detail model with a corresponding billboards, wherein the insert center point of each cross insert is coincident with the panel center point of the corresponding billboards.
When using a billboard panel instead of a cross tab, it is preferable that the orientation mode of the billboard panel be set to always face the camera so that the player can view the form of the object at different viewing angles.
Example two
Fig. 2 is a flowchart of a model rendering method according to a second embodiment of the present invention. This embodiment may be combined with each of the alternatives of one or more embodiments described above, where determining the billboard panel location data of the billboard detail model includes:
acquiring target vertex color data of a billboard panel in the billboard detail model, wherein each target vertex color data corresponds to panel center point position data of the corresponding billboard panel;
and determining the billboards position data based on the target vertex color data.
And before the target vertex color data of the billboards are obtained in the billboards detail model, the method further comprises:
determining the center point position data of the panel relative to the preset origin of the center point of the panel of the billboards;
compressing the center point position data of the surface patch according to the preset vertex color data attribute to obtain compressed surface patch center point position data with the preset vertex color data attribute;
And storing the data of the central point position of the compressed panel into initial vertex color data corresponding to each vertex of the corresponding billboards to obtain target vertex color data.
As shown in fig. 2, the method in this embodiment specifically includes:
s210, acquiring a target object model, wherein the target object model comprises a cross insert sheet profile model and a billboards detail model.
S220, determining the position data of the center point of the panel of the billboards relative to the preset origin.
Since the model only records the center point position data of the model itself after the model is generated, but does not record the center point position data of each billboards in the billboards detail model, the center point position data of each billboards needs to be additionally acquired and recorded.
Preferably, the position coordinate of the center point of the billboards relative to the preset origin can be used as the position data of the center point of the panels, wherein the preset origin can be the center point of the model itself or other preset position points.
S230, compressing the center point position data of the face patch according to the preset vertex color data attribute to obtain compressed face patch center point position data with the preset vertex color data attribute.
In this embodiment, after the patch center point position data is determined, the patch center point position data may preferably be stored in the vertex color data of the patch where the center point is located. Alternatively, the preset vertex color data attribute may be a numerical range of vertex color data, and the patch center point position data may be compressed to data within the numerical range of vertex color data by a compression processing method, for example. Alternatively, the preset vertex color data attribute may be a decimal point number of the vertex color data, and the patch center point data may be compressed to data having a decimal point number of the vertex color data by a compression processing method. The compressing of the patch center point position data may be performed by normalizing the patch center point position data, and may be exemplified by multiplying the patch center point position data by a preset first compression value or multiplying the patch center point position data by a preset second compression value. If the data attribute of the patch center point position data is exactly the same as the preset vertex color data attribute, the patch center point position data can be directly used as compressed patch center point position data.
For example, if the center point position data of the patch is a value exceeding 1 (for example, a value between 0 and 10), and the preset value range of the vertex color data is _ [0,1], the center point position data of the patch can be converted into data between [0,1] through the compression process.
And S240, storing the position data of the center point of the compressed panel in initial vertex color data corresponding to each vertex of the corresponding billboards to obtain target vertex color data.
Since the billboards are rendered vertex by vertex and each vertex is rendered by acquiring the patch center point position data, it is preferable that the compressed patch center point position data be stored in the initial vertex color data for each vertex. For example, if the billboard has three vertices, the compressed panel center point position data of the billboard is stored in the initial vertex color data corresponding to the three vertices, and if the billboard has six vertices, the compressed panel center point position data of the billboard is stored in the initial vertex color data corresponding to the six vertices.
Preferably, storing the compressed panel center point position data in initial vertex color data corresponding to each vertex of the corresponding billboards includes:
Storing X-axis coordinate values in the compressed patch center point position data into an R channel in the initial vertex color data;
storing Y-axis coordinate values in the compressed patch center point position data into a G channel in the initial vertex color data;
and storing the Z-axis coordinate value in the compressed patch center point position data into a B channel in the initial vertex color data.
In this embodiment, the coordinate values of X, Y and Z axis in the compressed surface patch center point position data may be stored in the corresponding R, G and B three color channels in the initial vertex color data, respectively, and the storage correspondence between the specific axis coordinate values and the color channels may be set according to actual needs. Illustratively, in addition to the correspondence described in the above embodiment, the X-axis coordinate value may be stored in the G-channel, the Y-axis coordinate value may be stored in the R-channel, and the Z-axis coordinate value may be stored in the B-channel; the X-axis coordinate values may also be stored in the G-channel, the Y-axis coordinate values in the B-channel, and the Z-axis coordinate values in the R-channel.
S250, acquiring target vertex color data of a billboards in the detailed billboards, wherein each target vertex color data corresponds to the position data of the center point of the corresponding billboards.
After the target object detail model is obtained, the position data of the center point of the patch corresponding to the corresponding vertex can be determined by reading the target vertex color data of each vertex in the billboard detail model. The target vertex color data of the billboard is the center point position data of the panel of the billboard.
S260, determining the billboard panel position data based on the target vertex color data.
Preferably, after the target vertex color data of each vertex is obtained, the patch center point position data corresponding to each vertex may be determined based on the target vertex color data, and the patch center point position data corresponding to each vertex and the vertex position data of each vertex may be used as billboard patch position data.
Preferably, determining the billboard patch position data based on the target vertex color data includes:
decompressing the target vertex color data to obtain the center point position data of the billboards corresponding to each vertex;
and taking vertex position data corresponding to each vertex and the position data of the center point of the billboard surface piece as the position data of the billboard surface piece.
For example, there are multiple billboards in the billboard detail model, and for each billboard, the shape of the panel is rectangular, and four vertexes are provided, and each vertex stores target vertex color data and vertex position data, and the target vertex color data and the vertex position data at each vertex are read point by point to obtain four groups of target vertex color data and vertex position data. Because the target vertex color data stores compressed patch center point position data, it is preferable to decompress the four compressed patch center point position data to obtain four patch center point position data, and use the four sets of patch center point position data and vertex position data as billboard patch position data.
Here, before the vertex position data corresponding to each vertex and the billboards center point position data are used as billboards position data, updating the vertex position data corresponding to each vertex according to the change of the player's viewing angle may be further included.
Specifically, before the player changes the viewing angle, the initial vertex position data corresponding to each vertex and the initial position data of the center point of the billboards may be preferably used as the initial position data of the billboards, and the target object model may be rendered and displayed to the player based on the initial position data of the billboards. When a change in the player's view angle is detected, for each vertex in the billboards, the current vertex position data may be determined using the initial vertex position data, the billboards center point position data, and the player's view angle data, and the initial vertex position data may be updated using the current vertex position data. After the current vertex position data corresponding to each vertex is obtained, the current vertex position data corresponding to each vertex and the position data of the center point of the billboard surface patch are used as the current position data of the billboard surface patch, and the target object model is rendered and displayed to a player based on the initial position data of the billboard surface patch.
And S270, rendering and displaying the target object model based on the billboards position data.
According to the model rendering method provided by the embodiment, a target object model is obtained, wherein the target object model comprises a cross insert overall model and a billboards detail model; determining the center point position data of the panel relative to the preset origin of the center point of the panel of the billboards; compressing the center point position data of the face patch according to the preset vertex color data attribute to obtain compressed face patch center point position data with the preset vertex color data attribute; storing the position data of the center point of the compressed panel in initial vertex color data corresponding to each vertex of the corresponding billboards to obtain target vertex color data; obtaining target vertex color data of a billboard panel in a billboard detail model, wherein each target vertex color data corresponds to panel center point position data of the corresponding billboard panel; the target object model is rendered and displayed based on the billboards, and the target object model is designed and rendered and displayed by using the two methods of the cross inserting sheet and the billboards, so that the defects of long rendering time, more memory occupation, obvious inserting sheet line effect of the model, attractive appearance and the like caused by excessive use of the triangular surface of the model are overcome, the rendering pressure of a game engine is relieved, the memory occupation is reduced, and meanwhile, the display picture is more attractive. In addition, the vertex color data is utilized to store the center point position data of the patch, so that extra storage space is not required, and resources are saved.
