D3D API - D3DRS_TEXTUREFACTOR

D3DRS_TEXTUREFACTOR

Color used for multiple-texture blending with the D3DTA_TFACTOR texture-blending argument or the D3DTOP_BLENDFACTORALPHA texture-blending operation. The associated value is a D3DCOLOR variable. The default value is opaque white (0xFFFFFFFF).

 

使用：

  g_pd3dDevice->SetTexture(0, g_pTexture);

  g_pd3dDevice->SetRenderState(D3DRS_TEXTUREFACTOR, 0xffff0000);

  g_pd3dDevice->SetTextureStageState(0, D3DTSS_COLOROP, D3DTOP_MODULATE);
  g_pd3dDevice->SetTextureStageState(0, D3DTSS_COLORARG1, D3DTA_TEXTURE);
  g_pd3dDevice->SetTextureStageState(0, D3DTSS_COLORARG2, D3DTA_TFACTOR);
  g_pd3dDevice->SetTextureStageState(0, D3DTSS_ALPHAOP, D3DTOP_DISABLE);

  g_pd3dDevice->SetTextureStageState(1, D3DTSS_COLOROP, D3DTOP_DISABLE);
  g_pd3dDevice->SetTextureStageState(1, D3DTSS_ALPHAOP, D3DTOP_DISABLE);
