To create an image on the screen, the CPU provides the necessary information of the objects: coordinates, color and alpha channel values, textures etc. From these data the Graphical Processing Unit (GPU) calculates the image through complex operations. The exact architecture may vary by manufacturers and by GPU families as well, but the general ideas are the same. The DirectX 10 pipeline stages to produce an image are:

1. Shader Model 3 added additional capabilities to shader model 2. Feature: Capability: Instruction Set: HLSL functions; Assembly instructions (see ps30 Instructions, Instructions - vs30); Register Set.
2. The Dynamic Shader Linkage 11 sample demonstrates use of Shader Model 5 shader interfaces and Direct3D 11 support for linking shader interface methods at runtime. The HDRToneMappingCS11 sample demonstrates how to setup and run the Compute Shader(CS for short later on), which is one of the most exciting new features of Direct3D 11.

1. Input-Assembler Stage - Gets the input data (the vertex information) of the virtual world.
2. Vertex-Shader Stage - Transforms the vertices to camera-space, lighting calculations, optimizations etc.
3. Geometry-Shader Stage - For limited transformation of the vertex-geometry.
4. Stream-Output Stage - Makes for Executed Instructions means '32 texture instructions and 64 arithmetic instructions.'
