TEXTURELODOFFSET(3G)

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.
