SetRenderState 设置渲染状态

1). 设置着色模式:

SetRenderState(D3DRS_SHADEMODE, D3DSHADE_FLAT) //设置平面着色模式

SetRenderState(D3DRS_SHADEMODE, D3DSHADE_GOURAUD) //设置格劳德着色模式

2). 设置多边形填充模式:

SetRenderState(D3DRS_FILLMODE, D3DFILL_POINT) //点填充模式，D3D在多边形的每个顶点绘制一个像素

SetRenderState(D3DRS_FILLMODE, D3DFILL_WIREFRAME) //线填充模式，D3D在多边形的每个边绘制一条线

SetRenderState(D3DRS_FILLMODE, D3DFILL_SOLID) //面模式，D3D默认模式，对多边形的面进行填充

3). 设置全景图形抗锯齿:

SetRenderState(D3DRS_MUTISAMPLEANTIALIAS, TRUE) //抗锯齿

SetRenderState(D3DRS_MUTISAMPLEANTIALIAS, FALSE) //不抗锯齿

4). 设置剔除模式:

SetRenderState(D3DRS_CULLMODE, D3DCULL_NONE) //不剔除任何面

5). 设置光照模式:

SetRenderState(D3DRS_AMBIENT, D3DCOLOR ambientColor); //为整个场景设置环境光

SetRenderState(D3DRS_SPECULARENABLE, TRUE); //激活镜面反射计算(D3D默认情况下关闭)

6). 启动/关闭深度测试:

SetRenderState( D3DRS_ZENABLE, TRUE ); //启用深度测试

7) 设置纹理过滤器

//线性纹理

SetSamplerState(0, D3DSAMP_MAGFILTER, D3DTEXF_LINEAR);

SetSamplerState(0, D3DSAMP_MINFILTER, D3DTEXF_LINEAR);

//最近点采样

SetSamplerState(0, D3DSAMP_MAGFILTER, D3DTEXF_ POINT);

SetSamplerState(0, D3DSAMP_MIPFILTER, D3DTEXF_POINT);

//各向异性纹理过滤

SetSamplerState(0, D3DSAMP_MINFILTER, D3DTEXF_ANISOTROPIC)

SetSamplerState(0, D3DSAMP_MIPFILTER, D3DTEXF_ ANISOTROPIC);

8)

SetRenderState( D3DRS_POINTSCALEENABLE, TRUE ); //打开缩放功能

9)

SetRenderState( D3DRS_POINTSCALE_A , FtoDW( 1.00f ));//设置因子，下同

SetRenderState( D3DRS_POINTSCALE_B , FtoDW( 1.00F ));

SetRenderState( D3DRS_POINTSCALE_C , FtoDW( 1.00f ));

10)

SetRenderState( D3DRS_POINTSIZE_MAX, FtoDW( 5.00f ));//设置点大小上限,下类似

SetRenderState( D3DRS_POINTSIZE_MAX, FtoDW( 5.00f ));

SetRenderState( D3DRS_POINTSPRITEENABLE , TRUE ) ; //打开点精灵效果

SetRenderState( D3DRS_AMBIENT, 0xffffffff ); //设置环境光颜色开启 ALPHA混合效果

11)

设置混合因子:

源:SetRenderState( D3DRS_SRCBLEND , D3DBLEND_SRCALPHA );

目的:SetRenderState( D3DRS_DESTBLEND , D3DBLEND_INVSRCALPHA);

第二个参数是 D3DBLEND的枚举结构。

//背景空的PNG图片，剔除背景

g_pMyd3dDevice->SetRenderState( D3DRS_ALPHABLENDENABLE, TRUE );//开启ALPHA混合功能

g_pMyd3dDevice->SetRenderState( D3DRS_SRCBLEND, D3DBLEND_SRCALPHA);//设置源混合因子为（As,As,As,As)

g_pMyd3dDevice->SetRenderState( D3DRS_DESTBLEND, D3DBLEND_INVSRCALPHA);//设置目标混合因子为（1-As,1-As,1-As,1-As);

g_pMyd3dDevice->SetRenderState( D3DRS_ALPHATESTENABLE, TRUE );//开启ALPHA测试功能

g_pMyd3dDevice->SetRenderState( D3DRS_ALPHAREF, 0x0f );//设置ALPHA测试参考值

g_pMyd3dDevice->SetRenderState( D3DRS_ALPHAFUNC,D3DCMP_GREATEREQUAL );//设置APLHA测试比较规则

//渲染

//在渲染完毕后，不要忘了关闭开启的功能

g_pMyd3dDevice->SetRenderState( D3DRS_ALPHATESTENABLE, FALSE );

g_pMyd3dDevice->SetRenderState( D3DRS_ALPHABLENDENABLE, FALSE );

//纹理透明

pd3dDevice-> SetRenderState(D3DRS_ALPHABLENDENABLE,TRUE);

pd3dDevice-> SetRenderState(D3DRS_SRCBLEND,D3DBLEND_SRCCOLOR);

pd3dDevice-> SetRenderState(D3DRS_DESTBLEND,D3DBLEND_INVSRCCOLOR);

//渲染

pd3dDevice-> SetRenderState(D3DRS_ALPHABLENDENABLE,FALSE);

// D3DRS_POINTSPRITEENABLE = TRUE,则将当前纹理整个映射到点精灵上去不用指定纹理坐标

g_D3DDevice->SetRenderState(D3DRS_POINTSPRITEENABLE, TRUE);

g_D3DDevice->SetRenderState(D3DRS_POINTSCALEENABLE, TRUE);

g_D3DDevice->SetRenderState(D3DRS_POINTSIZE, FtoDW(1.0));

g_D3DDevice->SetRenderState(D3DRS_POINTSIZE_MIN, FtoDW(1.0f));

g_D3DDevice->SetRenderState(D3DRS_POINTSCALE_A, FtoDW(0.0f));

g_D3DDevice->SetRenderState(D3DRS_POINTSCALE_B, FtoDW(0.0f));

g_D3DDevice->SetRenderState(D3DRS_POINTSCALE_C, FtoDW(1.0f));
