GLSL函数texelFetchOffset的CG等价物是什么

根据nVidia documentation的说法
tex2Dfetch -在给定采样器中执行未过滤的纹理查找。
使用以下重载之一:
float4 tex2Dfetch(sampler2D samp, int4 s)
float4 tex2Dfetch(sampler2D samp, int4 s, int texelOff)
int4 tex2Dfetch(isampler2D samp, int4 s)
int4 tex2Dfetch(isampler2D samp, int4 s, int texelOff)
unsigned int4 tex2Dfetch(usampler2D samp, int4 s)
unsigned int4 tex2Dfetch(usampler2D samp, int4 s, int texelOff)参数
samp
Sampler to lookup.
s
Coordinates to perform the lookup.
The level of detail is stored in the last component of the coordinate vector.
texelOff
Offset to be added to obtain the final texel. https://stackoverflow.com/questions/12961232
