0.8ms GPU operation times.
When execution renders, judge which part of three-dimensional land map needs to be rendered according to the depth of vegetation distribution map
Out.When the depth of vegetation distribution map is more than default value, it is the part blocked by vegetation to determine the three-dimensional land map, then does not enter
Row renders；When grace be less than default value than the depth of distribution map, it is the portion do not blocked by vegetation to determine the three-dimensional land map
Point, then rendered.
Alternatively, the original vegetation map picture of distant view vegetation is merged with landform top view, obtain vegetation first is planted
When being schemed, the color shown on landform top view can be first adjusted, then to the landform top view after adjustment to original vegetation map picture
Merged, so that original vegetation map picture shows different colors.Specifically, color map is obtained, wherein, color map bag
Include multiple color regions, the color in multiple color regions is identical or different；Using on color map adjustment landform top view
The color of display, the landform top view after being adjusted.
Fig. 4 is the schematic diagram of color map according to embodiments of the present invention.As shown in figure 4, there is difference in color map
Color, different size and color lump of different shapes, utilize the color shown on color map adjustment landform top view so that ground
The color in the color map is shown on shape top view on region corresponding with color map.For example, what landform top view was shown
Season is autumn, then the color map with red color can be used to be adjusted the color shown on landform top view,
When landform top view after the adjustment is merged with original vegetation map picture, just the vegetation on the first vegetation map can be shown
The effect of maple group.
Merged using the landform top view after adjustment with original vegetation map picture, that is to say, that adjusted by color map
The color of site preparation shape top view, so as to which the color shown in when landform top view is with original vegetation map as being merged is richer
Richness, and it is more vivid, close to the true colors of the Nature.Also, because color map can adjust landform top view
Some is different color so that the vegetation on the first vegetation map for merging to obtain more has a sense of hierarchy.
When showing vegetation in the first vegetation map, if the color value of the vegetation in the first vegetation map is all the same, meeting
Cause a problem：With the color and earth's surface of the vegetation of current view point (can be the position of the video camera in game picture) farther out
Color differ greatly so that the change of color is very lofty.In order to solve this problem, to original vegetation map picture and landform top
View is merged.
In fusion, original vegetation map vegetation as in is adjusted according to the distance of plant and video camera in original vegetation map picture
Color obtains the first vegetation map, wherein, the color of original vegetation map picture is faded to the increase of distance in landform top view
The color of earth's surface.
Specifically, the color of the vegetation shown in the first vegetation map is adjusted according to the distance of vegetation and video camera, by distance
The color of the vegetation of video camera farther out is adjusted to the color close to earth's surface in landform top view, the vegetation closer to the distance with video camera
Color of the color closer to vegetation in itself, so, the color of vegetation has natural transition according to the how far with video camera,
And the color of vegetation farther out and the color of earth's surface very close to so that vegetation is combined together with earth's surface, is showed more life-likely
The scene of real world.
As a kind of optional embodiment, a fusion factor is determined according to the distance of vegetation and video camera, utilizes this
Fusion factor adjusts the color of vegetation, is the function f (s, x) of distance, wherein, s represents the distance of vegetation and current view point, x tables
The color ratio gone out shown by showing vegetation under current distance.For example, the face by the vegetation of each position in original vegetation map picture
Colour is multiplied with fusion factor, and the vegetation color apart from video camera position farther out is than the vegetation color apart from video camera closer location
The color of earth's surface closer in topographic map.
Fig. 5 and Fig. 6 respectively illustrates the schematic diagram of original vegetation map picture and the schematic diagram of the first vegetation map after fusion.Compare
The color of vegetation that Fig. 6 can be seen that in Fig. 5 apart from video camera farther out with Fig. 5 differs larger with the color of earth's surface, transition not from
So, the color of the vegetation in Fig. 6 apart from video camera farther out and the color of earth's surface are very close to vegetation is combined together with earth's surface, more
Realistically show the scene of real world.
Alternatively, it is a simple dough sheet corresponding to the first vegetation map drawn in Billboard, the first vegetation map is
Draw out offline, because it is size-limited, and need to compress, this causes the first vegetation map drawn in Billboard
It is very fuzzy；Billboard vegetation and 3D vegetation are seamlessly transitted when switching using Screen Door technologies, even if so yet
It is the switching for being easy to perceive Billboard vegetation and 3D vegetation.In order that obtain Billboard vegetation and the switching of 3D vegetation
Shi Jinhang is seamlessly transitted, and the present invention can be increased by increasing Gaussian noise (as shown in Figure 7) in the first vegetation map alpha passages
Add Billboard details, when BillboardTree and 3D Tree switch also can transition it is very smooth.
Alternatively, the first vegetation map is arranged to the Distance Shortened with vegetation and current view point and reduces display first and plant
By the pixel in figure.
In real world, for same observer, experienced with a piece of vegetation, when from the place remote from distance
The vegetation density experienced when vegetation density ratio is from the near place of distance is bigger, i.e. distant view vegetation looks denser
(as shown in Figure 8), close shot vegetation are looked than sparse (as shown in Figure 9).In the game image of prior art, distant view vegetation
Density with close shot vegetation is identical.In game image, if the density of distant view vegetation and close shot vegetation all set
It is very high, then it is very high to the performance requirement of terminal, in addition, the density of close shot vegetation can influence NPC and other player when too high.
In order to solve problem above, the first vegetation map is arranged to the distance of vegetation and video camera in the first vegetation map
Shorten and reduce the pixel that shows of the first vegetation map, when the vegetation in the first vegetation map and video camera it is in larger distance when, first
The pixel that vegetation map is shown is more, so it can be seen that vegetation it is more intensive；When the vegetation in the first vegetation map and video camera
It is in small distance when, the pixel that the first vegetation map is shown is less, so it can be seen that vegetation it is more sparse, this has just reached remote
Scape vegetation looks denser, and close shot vegetation is looked than sparse technique effect, and due to the density of close shot vegetation
It is not high, do not interfere with NPC.In addition, the requirement to terminal capabilities is also than relatively low.
For example, when the vegetation in the first vegetation map and the distance of video camera be first apart from when, show the picture of the first quantity
Element；When the vegetation in the first vegetation map and the distance of video camera are second distance, the pixel of the second quantity is shown.First away from
During from more than second distance, the pixel of the second quantity of display will be less than the quantity of the first pixel, that is to say, that with distance
Reduce, the quantity of the pixel of display is also being reduced, also, the pixel not shown is random.
Alternatively, the distance of the plant in the first vegetation map and current view point is carried out at diminution to the first vegetation map
Reason.
Mountain in scene of game is not special height, and sets and drawn according to actual size, therefore, such as Figure 10 institutes
Show, in the place apart from video camera farther out, can seem tree very high mountain very little, and this is different from real world, can influence image
Degree true to nature.
In embodiments of the present invention, the first vegetation map in vegetation distribution map is carried out according to the distance between video camera
Non- Scaling processing, i.e. the distance between video camera is more remote, then the multiple reduced is bigger.By image as shown in Figure 10
The image obtained after diminution is handled is as shown in figure 11, and the vegetation in Figure 11 on distant mountain is reduced.Caused benefit is：Set quilt
Diminution, which seems that mountain is grander, imposing manner；The tree of distant place looks shorter, meets the direct feel of human eye, and image seems
It is more true to nature, enhance the third dimension of image；Meanwhile the quantity of pixel is reduced in the first vegetation map of diminution, reduces display
System consumption required for first vegetation map, also just reduce the requirement to terminal.
Alternatively, after vegetation distribution map is obtained, when showing landform border on display interface, vegetation distribution map is entered
Row mirror image processing；Vegetation distribution map after showing mirror image in the region beyond landform border.
In the prior art, some false mesh are often put at the edge of map and comes analog map border, for vegetation
Do not process typically, to the end for feeling to have gone to the world of game player, as shown in figure 12.
In the embodiment of the present invention, beyond landform border region show mirror image after vegetation distribution map, landform border with
Together with outer region is seamless spliced with the region in landform border, also there is dense vegetation in the region beyond landform border.And
And due to vegetation distribution map is carried out the obtained image of mirror image processing than with region of the fine arts method beyond topographic map brush out come
Effect it is more true to nature, so as to which the authenticity of scene of game be improved greatly.Moreover, mirror image processing is carried out to vegetation distribution map
In, it is not necessary to additionally do art work, the vegetation distribution map after mirror image is as shown in figure 13.As a kind of optional embodiment,
Region beyond landform border shows the vegetation distribution map after 2km mirror image.
, can be according to the position at the topographic map edge residing for player and the visual angle model of eyes as a kind of optional embodiment
It is trapped among the region beyond landform border and shows several (1 to 8) mirror image topographic maps, as shown in figure 14.
