帮忙解释一下有关纹理的问题

hycoldrain

关于纹理的代码请教
g_pD3DDevice->SetSamplerState(0,D3DSAMP_MAGFILTER,D3DTEXF_LINEAR);
g_pD3DDevice->SetSamplerState(0,D3DSAMP_MINFILTER,D3DTEXF_LINEAR);
g_pD3DDevice->SetSamplerState(0,D3DSAMP_MIPFILTER,D3DTEXF_POINT);

为什么写3行SetSamplerState函数，都是做什么用的？还有第二个参数D3DSAMP_MAGFILTER，D3DSAMP_MINFILTER都是什么意思？谢谢

从MAGFILTER等看，貌似是设置纹理滤波方式的。

pyphehe

D3DSAMP_MAGFILTER
Magnification filter of type D3DTEXTUREFILTERTYPE. The default value is D3DTEXF_POINT.
D3DSAMP_MINFILTER
Minification filter of type D3DTEXTUREFILTERTYPE. The default value is D3DTEXF_POINT.
D3DSAMP_MIPFILTER
Mipmap filter to use during minification. See D3DTEXTUREFILTERTYPE. The default value is D3DTEXF_NONE.
