Detailed Description
A sampler state used by GFXStateBlockData.
The samplers define how a texture will be sampled when used from the shader or fixed function device
- Example:
singleton GFXSamplerStateData(SamplerClampLinear) { textureColorOp = GFXTOPModulate; addressModeU = GFXAddressClamp; addressModeV = GFXAddressClamp; addressModeW = GFXAddressClamp; magFilter = GFXTextureFilterLinear; minFilter = GFXTextureFilterLinear; mipFilter = GFXTextureFilterLinear; };
There are a few predefined samplers in the core scripts which you can use with GFXStateBlockData for the most common rendering cases:
- SamplerClampLinear
- SamplerClampPoint
- SamplerWrapLinear
- SamplerWrapPoint
