NAME
tex2DARRAYlod - performs a texture lookup with a specified level of detail in a given sampler array.SYNOPSIS
float4 tex2DARRAYlod(sampler2DARRAY samp, float4 s) float4 tex2DARRAYlod(sampler2DARRAY samp, float4 s, int texelOff)
int4 tex2DARRAYlod(isampler2DARRAY samp, float4 s) int4 tex2DARRAYlod(isampler2DARRAY samp, float4 s, int texelOff)
unsigned int4 tex2DARRAYlod(usampler2DARRAY samp, float4 s) unsigned int4 tex2DARRAYlod(usampler2DARRAY samp, float4 s, int texelOff)
PARAMETERS
- samp
- Sampler array to lookup.
- s
- Coordinates to perform the lookup.The value used to select the layer should be passed in the vector component right after the regular coordinates. The level of detail value should be passed as the last component of the coordinate vector.
- texelOff
- Offset to be added to obtain the final texel.
DESCRIPTION
Performs a texture lookup with a specified level of detail in sampler samp using coordinates s, the texture to be sampled is selected from the layer specified in the coordinates.PROFILE SUPPORT
tex2DARRAYlod is only supported in gp4 and newer profiles.SEE ALSO
