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

P

lod

offset

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.
