Description
Technical Field
The present invention relates to the field of view generation, and in particular, to a game field of view generation method, apparatus, electronic device, and storage medium.
Background
In MOBA (Multiplayer Online Battle Arena, multiplayer online tactical game), the game field of view is an important component of countermeasure rules and playability. In the implementation of the field of view generation technology, a large number of game objects such as roles, buildings, objects and the like of the field of view layer and the scene map are required to be mixed and judged so as to render the size, shape and color of the field of view. Rendering processes typically include operations to gather, filter, calculate polygons, submit consumption performance of rendering, etc., of game objects within the screen device.
Most of the existing visual field implementation modes are based on the implementation of the foggy lattices, namely, the visual attribute of each foggy lattice is determined in the range of visual field equipment according to the position of a principal angle and the radius of the visual field, and the visible attribute is in the visual field, and the invisible attribute is out of the visual field.
However, the above-described solution has some drawbacks. First, when the grid is large, the field of view changes with a non-smooth and discontinuous visual experience when switching from one grid to the next. Second, since the shapes of the plurality of lattices constituting the visual field are fixed, the visual field area effect of an arbitrary shape cannot be achieved. Finally, the view field area generated based on the ray trace cannot be achieved.
Furthermore, another implementation is now based on pure polygon rendering. A significant disadvantage of this solution is that the shape can only be limited to a combination of polygons, and that a smoother shape and field of view containing areas of different color or transparency cannot be achieved.

in the embodiment of the invention, the point light source object is a light source structure body capable of emitting simulated light, and the irradiation range of the point light source object can be circular, fan-shaped or other self-defined shapes.
In the embodiment of the invention, a point light source object can be arranged at the position of the character, and the irradiation range of the point light source object is used for symbolizing the visual field range of the character.
in the embodiment of the invention, all object graphs within the screen range can be searched based on a preset first device, the polygonal shape and the position of the object graph can be determined, and the vertex position information of each vertex of each object graph can be further determined.

The light emitted by the point light source object is 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 invention, the first effective side information set of the object can be generated according to the position information of the point light source object and the vertex position information of all object graphs.

Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a game field generating method according to another embodiment of the present invention. Specifically, the method comprises the following steps:
in the embodiment of the invention, the polygon vertex data of the object graph input from the outside can be received to generate the object graph in the preset screen. The generated object graph 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 simulated light, and the irradiation range of the point light source object can be circular, fan-shaped or other self-defined shapes.
In the embodiment of the invention, a point light source object can be arranged at the position of the character, and the irradiation range of the point light source object is used for symbolizing the visual field range of the character.

s56, integrating the first effective edges of all object graphs to obtain a first effective edge information set of the objects.
As shown in fig. 3, the point light source object may emit a plurality of light rays, each of which passes through a vertex of the object diagram. And calculating the included angle of the light rays corresponding to any two vertexes of the same object diagram. The two vertices with the largest included angles are taken as target vertices, such as A, B in fig. 3. Connecting A, B to obtain a target connection line AB, and taking the edge line of the object graph of the target connection line AB, which is close to the point light source object, as a first effective edge to obtain 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 edge, the correlation between the light scattered by the point light source object and the screen edge can be calculated, so as to determine the second effective side information set.
In one example, step 207 may include the sub-steps of:
s71, determining an unobstructed area according to a first effective side information set of the object and position information of a point light source object;

In the embodiment of the invention, the light rays of the point light source object which are not blocked by the first effective side information set can be intersected with the screen side line to obtain the second effective sides, 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 and the second effective side information set of the object 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 sub-steps of:
s81, generating a plurality of dark areas by adopting a first effective side information set, a second effective side information set and light rays of the object;
s82, generating a first view map based on the dark area.
In a specific implementation, an area surrounded by the screen edge line except the intersected first effective edge, the light ray and the second effective edge in the screen edge line is used as a dark area, so that a plurality of polygonal areas are obtained. And respectively transmitting the data of the polygonal area into a preset first device, calculating a first view diagram by the first device, and outputting the calculated first view diagram to a first storage area for standby.

In the embodiment of the invention, the second visual field rendering script can be executed according to the preset second device, so as to obtain a second visual field diagram.
In one example, step 209 may include the sub-steps of:
s91, acquiring the radius of the point light source object;
s92, generating a visual area according to the radius and the first view map; the visible area comprises a full visible area and a color gradient area;
s93, setting an area outside the visible area in the screen as a shadow area, and generating a second view map.
In a specific implementation, whether each pixel position in the first view is visible in the second view may be calculated according to the irradiation radius of the point light source object and the dark color region in the first view.
It should be noted that whether the object graph is ultimately visible is a comprehensive result for the pixels C on the object that are located within the radius of the light source; it is possible to first acquire its first visibility in the first view, and then acquire its second visibility (visible within the light source radius, invisible outside the light source radius) on the basis of the division of the light source radius. And performing logic AND operation on the first visibility and the second visibility to obtain the final visibility.
And then determining the visible area according to the radius of the light source and the visibility of each object graph in the screen. The visible area comprises a full visible area and a color gradient area. The full visible area is an area which takes a point light source object as a circle center and has no object diagram at all; the color gradient region is a region outside the full visible region and the object diagram in the visible region.
In addition, the area outside the visible area, including the object diagram itself, may be set as a shadow area. The second view map can be obtained by adjusting the pixels in the first view map as described above.
In an implementation, the second coordinates of the point light source object in the view map may be calculated according to the first position coordinates of the light source in the game scene. And transmitting the first view map into a view second rendering script, and calculating the color of each pixel in the second view map by combining the second coordinates of the point light source object in the view map to generate a second view map. The resulting second view may be as shown in fig. 6.
In an embodiment of the present invention, the method may further include: receiving highlight object data; a highlight item display region is generated in the second view based on the highlight item data.
The highlight object is an object which is not displayed as a shadow dark color in a shadow area, but is illuminated with light. It may set the pixel color inside the highlight object to the light 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 view field diagram and the second view field diagram, and adjusts the light and shade change in the screen based on the scattering and shielding conditions of the light source, so that the light and shade change in the screen has smoother and continuity.
