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.
