Chapter 3 introduces pixel shaders
Read this article shows that you have agreed to the statement
The pixel shader is a program executed on the GPU of the graphics card during rasterization processing of each pixel. (Not like the vertex shader, Direct3D does not use the software analog pixel shader function.) It actually replaces the multiTexturing stage of the fixed function line and gives us directly manipulating a separate pixel and access The ability of pixel texture coordinates. This direct access to pixels and texture coordinates allows us to achieve various effects, such as multiTexturing, per pixel lighting, depth of field, cloud simulation (Cloud Simulation) (CLOUD SIMULATION) (Cloud Simulation), DEPTH OF FIELD Fire Simulation, Sophistated Shadowing Technique.
The version of the pixel shader supported by graphics cards can be checked by the Pixelshaderversion member and D3DPS_Version macro of the D3DCAPS9 structure. The following code snippet shows this:
