Directx10 Study Notes (2)-Development History of DirectX

1. directx1.0: Born for games;

2. directx2.0: the appearance of a 3D prototype. DirectX has DirectDraw (1996 );

3. directx3.0: d3d development and growth (1997 );

4. directx5.0: d3d is becoming increasingly powerful. The first introduction of atomization support makes 3D games more realistic;

5. directx6.0: authoritative d3d appearance;

6. directx7.0: authoritative d3d support for T & L. The Chinese name is "coordinate conversion and illumination ";

7. directx8.0: Crazy about d3d. It introduced the concept of "pixel rendering" for the first time, as well as the pixel shader engine and vertx shade engine, reflected in special effects is the dynamic light and shade effect;

8. directx9.0: refreshing and improved PS and vs versions. ps2.0 has a fully programmable architecture that can calculate texture effects and realize dynamic texture maps, by increasing the flexibility of the vertex program, vs2.0 significantly improves the performance of the earlier version of vs. It adds new control commands and can replace the previously dedicated independent coloring program with a common program, the efficiency has been improved many times, the number of cyclic operation commands has been increased, the working time has been reduced, the processing efficiency has been improved, and the number of coloring commands has been increased from 128 to 256. In addition, vs2.0 also added the floating point data processing function, breaking through the previously limited PC image quality in mathematical precision obstacles.
