加入了影子后的效果
渲染樹(shù)目紋理之前，進(jìn)行如下設(shè)置
Device->SetRenderState(D3DRS_ALPHABLENDENABLE,true);
Device->SetRenderState(D3DRS_SCRBLEND,D3DBLEND_SCRALPHA);
Device->SetRenderState(D3DRS_DESTBLEND,D3DBLEND_INVSCRALPHA);
Device->SetRenderState(D3DRS_ALPHATESTENABLE,true);
Device->SetRenderState(D3DRS_ALPHAREF,0x0);
Device->SetRenderState(D3DRS_ALPHAFUNC,D3DCMP_GREATEREQUAL);
渲染陰影的時(shí)候，使用的是同一紋理，但需進(jìn)行如下設(shè)置
Device->SetRenderState(D3DRS_SCRBLEND,D3DBLEND_INVSCRALPHA);
調(diào)了一下午，才調(diào)出這陰影，難得呀~~`
