The DirectX 9.0 specification ´Â ´ÙÀ½ÀÇ »õ·Î¿î ±â´ÉÀ» Æ÷ÇÔÇÑ´Ù.
- Pixel Shader 2.0. DirectX 9.0 exposes true programmability of
the pixel shading engine. This makes procedural shading on a GPU possible
for the first time.
- Vertex Shader 2.0. DirectX 9.0 dramatically enhances the power
of the previous DirectX vertex shader by increasing the length and flexibility
of vertex programs.
- High-precision, floating-point color. DirectX 9.0 breaks the mathematical
precision barrier that has limited PC graphics in the past. Precision,
and therefore visual quality, is increased with 128-bit floating-point color
per pixel.
