请教几个DirectX的问题
1:切线贴图就是法线贴图的意思么?
如果不是,那两者有什么区别?
2:The NPatch mode segments 是什么意思?
原文:
The NPatch mode segments The NPatch mode segments from IDirect3DDevice9::SetNPatchMode
3:如下语句是什么意思:
The source primitive is used as a light map that scales the contents of the frame buffer to
darken it when appropriate
如果要看上下文,参阅下面的内容
Another application of alpha blending is to control the lighting in a 3D scene, also called
light mapping. Setting the source blend state to D3DBLEND_ZERO and the destination blend
state to D3DBLEND_SRCALPHA darkens a scene according to the source alpha information. The
source primitive is used as a light map that scales the contents of the frame buffer to
darken it when appropriate. This produces monochrome light mapping.
