NAME
textureLodOffset - perform a texture lookup with explicit level-of-detail and offset
DECLARATION
gvec4 textureLodOffset(gsampler1D sampler, float P, float lod, int offset); gvec4 textureLodOffset(gsampler2D sampler, vec2 P, float lod, ivec2 offset); gvec4 textureLodOffset(gsampler3D sampler, vec3 P, float lod, ivec3 offset); float textureLodOffset(sampler1DShadow sampler, vec3 P, float lod, int offset); float textureLodOffset(sampler2DShadow sampler, vec4 P, float lod, ivec2 offset); gvec4 textureLodOffset(gsampler1DArray sampler, vec2 P, float lod, int offset); gvec4 textureLodOffset(gsampler2DArray sampler, vec3 P, float lod, ivec2 offset); float textureLodOffset(sampler1DArrayShadow sampler, vec3 P, float lod, int offset);
PARAMETERS
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.
DESCRIPTION
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.
