OpenGL ES 3.0 element combination and Rasterization (iii)

Primitives are geometric objects that can be drawn by OpenGL ES, such as triangles, lines, or sprites. In the entity composition process

, each element must be judged whether it is located in the projection intercept, if the element is not completely inside the truncated body, it will be considered tiling clipping, if it is completely in the plane, will be discarded, and then the vertex position is converted to screen coordinates, the culling operation can discard some elements, depending on whether the entity is on the front or back, cut and reject     Elements into the rasterization phase. Rasterization is the process of converting an element into a two-dimensional fragment, executed by a fragment shader, and a two-dimensional fragment pixel can be drawn on the screen.
