textureLodOffset — perform a texture lookup with explicit level-of-detail and offset
gvec4 textureLodOffset( | gsampler2D sampler, |
| vec2 P, | |
| float lod, | |
ivec2 offset); |
gvec4 textureLodOffset( | gsampler3D sampler, |
| vec3 P, | |
| float lod, | |
ivec3 offset); |
float textureLodOffset( | sampler2DShadow sampler, |
| vec3 P, | |
| float lod, | |
ivec2 offset); |
gvec4 textureLodOffset( | gsampler2DArray sampler, |
| vec3 P, | |
| float lod, | |
ivec2 offset); |
sampler Specifies the sampler to which the texture from which texels will be retrieved is bound.
P Specifies the texture coordinates at which the texture will be sampled.
lod Specifies the explicit level-of-detail from which texels will be fetched.
offset Specifies the offset that will be applied to P before texels are fetched.
textureLodOffset performs a texture lookup at coordinate P from the texture bound to sampler with an explicit level-of-detail as specified in lod. Behavior is the same as in textureLod except that before sampling, offset is added to P.
