textureLodOffset

Name

textureLodOffset — perform a texture lookup with explicit level-of-detail and offset

Declaration

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);

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.
