Specific embodiment
The present invention is further described in detail below with reference to the accompanying drawings and embodiments.It should be appreciated that described herein
Specific embodiment is only used to explain the present invention, is not intended to limit the present invention.
Divide below with reference to the embodiment that track is presented to the relevant technologies in the example that navigation routine is presented on map
Analysis.
When map and navigation routine is presented in mobile terminal, the navigation routine presented on map is usually constructed with certain width
It spends (such as 20 pixels)；To avoid the setting-out interface renderings navigation routine using OpenGL from will lead to the obvious problem of pixel sawtooth,
The mode that the relevant technologies generally use triangular texture textures draws navigation routine, as shown in Figure 1, specifically including following step
Suddenly：
Step 101, starting point, terminal and the position passed through of original navigation routine are obtained.
Original navigation routine as shown in Figure 2 is a line segment.
Step 102, it is modeled for navigation routine.
As shown in figure 3, expanding a fixed width to both sides to the starting point of original navigation routine, terminal and the position passed through
Degree (possessed width when navigation routine is presented as needed and determines for the width specifically extended), determines there is one fixed width
For showing the region of navigation routine, then the region is divided with multiple triangles, it is total to form 1,2,3,4,5,6,7,8
8 vertex and 012,123,234,345,456,678 totally 6 triangles.
Step 103, texture coordinate is calculated based on modeling result.
The texture coordinate for constituting the triangle of above-mentioned zone (region of display navigation routine) is namely calculated, triangle
Texture coordinate include each point in triangle two-dimensional coordinate indicate and corresponding color value.
Step 104, it calls the setting-out interface of OpenGL to be based on texture coordinate and draws navigation routine.
Step 101 is executed to step 103 by application processor, and triangular apex data are transmitted at image by application processor
Device is managed, as shown in figure 4, image processor carries out texture padding in texture image to each triangular basis, to draw out Fig. 5 institute
The navigation routine shown (navigation routine is for filling black shown in Fig. 5).
The texture coordinate of each triangle is different, and 012,123,456,567 4 triangle on both sides, is used in Fig. 4
The cup head at drawn path both ends can be connected between different navigation route by cup head.
The mode of above-mentioned drafting navigation routine can cause frequently to occupy to processor and memory, and processing is time-consuming, influence
The response performance of mobile terminal；For example, mobile terminal needs the shape of the track presented constantly to convert in practical application, it is right
It requires to carry out above-mentioned modeling processing in each track, needs different display effects (such as real even for same track
Line display effect and dotted line display effect) it is also required to carry out modeling processing respectively, cause to make application processor and memory source
At excessive consumption, especially when track is continuously presented, (such as user continuously draws rail by touch control operation in application of drawing
When mark).
For the above problem that track is presented in the terminal, referring to Fig. 6, in the embodiment of the present invention, texture maps are obtained

Although 1 and line segment 2 it is corresponding with navigation routine, be not the actual navigation routine that mobile terminal is finally presented, but mobile
The line segment for the correspondence navigation routine that the application processor of terminal is determined, the corresponding navigation routine 2 of middle conductor 2 need to have real
Existing display effect, the display effect that the corresponding navigation routine 1 of line segment 1 needs to have dotted line；
For line segment 2, due to being linear type, beginning and end shown in Fig. 10 is determined based on line segment 2, and be based on and void
The corresponding density of line effect filling point between beginning and end, when graphics processor replaces point to be drawn using texture image
When processed, the navigation routine 2 drawn out is phantom line segments；
For line segment 1, due to being broken line type, starting point, terminal shown in Figure 11 and inflection point, and base are determined based on line segment 1
In density filling point between starting point and inflection point, inflection point and terminal corresponding with effect is realized, when graphics processor uses texture
The navigation routine 1 that image replaces point when being drawn, to be drawn out is real segment；
It should be pointed out that as shown in Figure 10 and Figure 11, when dividing to target trajectory, the granularity of the point used is usual
It will use when being that human eye can not be differentiated, therefore being divided to target trajectory and a little the width of target trajectory expanded to obtain target
The point set of track, to the navigation routine that can be drawn out can be made to have when replacing point to be drawn using texture graphics
The discernmible width of human eye, rather than show as one can not resolution width filament, to have the effect of eye-catching.
The navigation routine drawn out is as shown in figure 12, and navigation routine is mapped to map (after target image) finally in movement
