Android OpenGL ES plotting tutorial 3: Drawing GraphicsAfter defining the shapes to be drawn by OpenGL, you certainly want to draw them. Using OpenGL ES 2.0 to draw a graph may require more code than you think, because the API provides a large number of graphic rendering pipeline control interfaces.This chapter describ

When we draw a geometric image above, do you think our plot scope is too narrow? Coordinates can only be from-1 to 1, and can only be the right X axis, Y axis up, Z axis vertical screen. These limitations cause a lot of inconvenience to our drawing.

Note that the coordinate system of the plane is not fixed. We can operate on it to make our projection plane work in any coordinate system (e.g ., we can specify that the origin of OpenGL ES is in the lower left corner

Glactivetexture: select a texture unit. The texture function of the line plane applies to the texture unit. The parameter is the symbol constant gl_texturei, and the value range of I is 0 ~ N-1, n is the maximum number of texture units supported by OpenGL implementation, here, because the batch processing only has one texture,
operation speed is fast, but it is slightly less convenient to program, and the image effect is also worse than the RGB color. StarCraft may represent the screen effect of a 256-color table. Although it can run smoothly on a very bad PC, from the current perspective, the screen effect is insufficient.Currently, the performance of PC is sufficient to use RGB color in various scenarios. Therefore, the index color is not mainstream in PC program development. Of course, some small devices, such as
