Description
Technical Field
The present invention relates to the field of view generation technologies, and in particular, to a method and an apparatus for generating a game view, an electronic device, and a storage medium.
Background
In MOBA (Multiplayer Online Battle Arena), the game view is an important component of the rules of confrontation and playability. In the technical implementation of the generation of the view area, a large number of game objects such as characters, buildings, objects and the like of the view layer and the scene map are required to be mixed and judged so as to render the size, shape and color of the view area. The rendering process typically includes operations for gathering, filtering, polygon computation, rendering, etc. performance of game objects within the scope of the screen device.
Most of existing visual field implementation modes are based on implementation of the fog pattern, namely the visual property of each fog pattern is in the visual field if being visible and out of the visual field if not visible within the range of visual field equipment determined according to the position of the main corner and the radius of the visual field.
However, the above solution has some drawbacks. First, when the grid is large, the field of view changes with an uneven and discontinuous visual experience when switching from one grid to the next. Secondly, since a plurality of lattice shapes constituting the visual field are fixed, the visual field area effect of an arbitrary shape cannot be achieved. Finally, the field of view generated based on the ray trajectories is not possible.
Furthermore, another existing implementation is a pure polygon rendering based scheme. A significant disadvantage of this approach is that the shape can only be limited to a combination of polygons, and a smoother shape and a field of view containing regions of different color or transparency cannot be achieved.

Referring to fig. 1, fig. 1 is a flowchart illustrating steps of a game view generation method according to an embodiment of the present invention.

In the embodiment of the invention, a point light source object can be arranged at the position where the character is located, and the illumination range of the point light source object represents the visual field range of the character.
103, acquiring vertex position information of each vertex of all object graphs in a screen;
in the embodiment of the invention, based on the preset first device, all object graphs in the screen range are searched, the polygon shape and the position of each object graph are determined, and the vertex position information of each vertex of each object graph is further determined.
104, generating a first effective side information set of the object according to the position information of the point light source object and the vertex position information of all object graphs;
the first effective edge information set of the object is a set of edges of each object actually irradiated by the point light source object.
The light emitted by the point light source object can be shielded by the object graph, and the shielding range is positioned between two vertexes corresponding to two connecting lines with the largest included angle in the connecting lines of the point light source and each vertex of the object graph. Therefore, in the embodiment of the present invention, the first valid side information set of the object may be generated according to the position information of the point light source object and the vertex position information of all object graphs.
105, acquiring a screen sideline of a screen;
the second effective side information set is a set of partial screen side lines irradiated by the light of the point light source object.
According to the position of the point light source object, the first effective side information set of the object and the actual position of the edge line of the screen, the correlation between the light rays scattered out of the point light source object and the edge line can be calculated, and therefore the second effective side information set is determined.
after the position information of the point light source object, the first effective side information set of the object and the second effective side information set are obtained, the first view map can be generated by combining the second effective side information set according to the shielding condition of the first effective side information set of the object on the point light source object.
And step 108, generating a second view map according to the point light source object and the first view map.
In the embodiment of the present invention, after the first view map is acquired, the brightness change of the first view map may be adjusted according to the view range of the point light source object, so as to obtain the second view map.
The invention combines the point light source object, the first effective side information set and the second effective side information set of the object to generate the first visual field image and the second visual field image, and adjusts the light and shade change in the screen according to the scattering and shielding conditions of the light source, so that the light and shade change in the screen has smoothness and continuity.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for generating a game field of view according to another embodiment of the present invention. The method specifically comprises the following steps:
in the embodiment of the invention, polygon vertex data of an object graph input from the outside can be received to generate the object graph in a preset screen. The generated object map may be as shown in fig. 3.
in the embodiment of the invention, the point light source object is a light source structure body capable of emitting analog light, and the irradiation range of the point light source object can be a circle, a sector or other self-defined shapes.
In the embodiment of the invention, a point light source object can be arranged at the position where the character is located, and the illumination range of the point light source object represents the visual field range of the character.
in the embodiment of the invention, based on the preset first device, all object graphs in the screen range are searched, the polygon shape and the position of each object graph are determined, and the vertex position information of each vertex of each object graph is further determined.
the light emitted by the point light source object can be shielded by the object graph, and the shielding range is positioned between two vertexes corresponding to two connecting lines with the largest included angle in the connecting lines of the point light source and each vertex of the object graph. Therefore, in the embodiment of the present invention, the first valid side information set of the object may be generated according to the position information of the point light source object and the vertex position information of all object graphs.
In one example, step 205 may include the following sub-steps:
s51, connecting the point light source object with each vertex of each object graph respectively to obtain a plurality of light rays;
s52, calculating the included angle between any two light rays according to the position information of the point light source object and the vertex position information of each vertex of the object graph;
s53, taking two vertexes corresponding to the two light rays with the largest included angle as target vertexes;
s54, connecting the target vertex of the object graph to obtain a target connecting line;
s55, obtaining a side line between the target connecting line and the point light source object as a first effective side of the object graph;
s56, the first effective edges of all the object graphs are integrated to obtain a first effective edge information set of the objects.
As shown in FIG. 3, the point light source object can emit a plurality of light rays, each light ray passing through a vertex of the object map. And calculating the included angle of the light rays corresponding to any two vertexes of the same object graph. Two vertexes with the largest included angle are taken as target vertexes, such as A, B in fig. 3. Connecting A, B to obtain a target connection line AB, and taking the edge of the object graph of the target connection line AB close to the point light source object as the first effective edge, then obtaining all the first effective edges of the object graph.
And integrating the first effective edges of all the object graphs to obtain a first effective edge information set of the objects in the screen.
in the embodiment of the invention, according to the position of the point light source object, the first effective side information set of the object and the actual position of the screen side line, the correlation between the light rays scattered out of the point light source object and the screen side line can be calculated, so that the second effective side information set is determined.
In one example, step 207 may include the following sub-steps:
s71, determining a non-blocking area according to the first effective side information set of the object and the position information of the point light source object;
and S72, taking the line segment which is intersected with the non-occlusion area in the screen edge as a second effective edge, and generating a second effective edge information set.
In the embodiment of the invention, the intersection calculation can be carried out on the light rays of the point light source object which are not shielded by the first effective side information set and the edge line of the screen to obtain the second effective side, and all the second effective sides are collected to obtain the second effective side information set.
in the embodiment of the invention, after the position information of the point light source object, the first effective side information set of the object and the second effective side information set are obtained, the first view map can be generated by combining the second effective side information set according to the shielding condition of the first effective side information set of the object on the point light source object.
In one example, step 208 may include the following sub-steps:
s81, generating a plurality of dark areas by using the first effective side information set, the second effective side information set and the light rays of the object;
s82, a first view map is generated based on the dark regions.
In a specific implementation, the regions surrounded by the first effective edge, the ray, and the screen edge other than the second effective edge in the screen edge that intersect may be used as dark regions, so as to obtain a plurality of polygonal regions. And respectively transmitting the data of the polygonal area into a preset first device, calculating a first view map by the first device, and outputting the calculated first view map to a first storage area for later use. The resulting first view is shown in fig. 5.
The first device is a device for executing a script. A script is a set of program code for implementing program logic, executed by a rendering device.
Step 209 generates a second field of view map from the point source object and the first field of view map.
In the embodiment of the present invention, the second view rendering script may be executed according to a preset second device, so as to obtain a second view map.
In one example, step 209 may include the following sub-steps:
s91, acquiring the radius of the point light source object;
s92, generating a visual area according to the radius and the first visual field diagram; the visible area comprises a complete visible area and a color gradient area;
s93, a second view field map is generated by setting the region outside the visible region in the screen as a shadow region.
In a specific implementation, whether each pixel position in the first view field image is visible in the second view field image or not can be calculated according to the irradiation radius of the point light source object and a dark color area in the first view field image.
It should be noted that whether the object map is finally visible is a result of integration, for the pixel C located within the radius of the light source on the object; first visibility in the first view field diagram can be acquired, and then second visibility based on the light source radius (visible within the light source radius and invisible outside the light source radius) can be acquired. And performing logic AND operation on the first visibility and the second visibility to obtain the final visibility.
Then, the visible area is determined according to the radius of the light source and the visibility of each object map in the screen. Wherein the visible area comprises a complete visible area and a color gradient area. The complete visual area is an area which takes the point light source object as the center of a circle and has no object picture in the visual area; the color gradient area is the complete visual area in the visual area and the area outside the object picture.
In addition, the region outside the visible region, including the object map itself, may be set as a shadow region. By adjusting the pixels in the first view map, the second view map can be obtained.
In an implementation, the second coordinate of the point light source object in the view map can be calculated according to the first position coordinate of the light source in the game scene. And transmitting the first view map into a second view rendering script, and calculating the color of each pixel in the second view map by combining second coordinates of the point light source object in the view map to generate the second view map. The resulting second field of view may be as shown in fig. 6.
In the embodiment of the present invention, the method may further include: receiving highlight object data; a highlighted item display area is generated in the second view map based on the highlighted item data.
The highlight object is an object which is not displayed as shadow dark color but is illuminated with light color in the shadow area. It may set the pixel color inside the highlight object to the illumination color by inputting the polygon data of the highlight object into the third rendering script.
The invention combines the point light source object, the first effective side information set and the second effective side information set of the object to generate the first visual field image and the second visual field image, and adjusts the light and shade change in the screen according to the scattering and shielding conditions of the light source, so that the light and shade change in the screen has smoothness and continuity.
