Name
textureSize — retrieve the dimensions of a level of a texture
Declaration
ivec2 textureSize( | gsampler2D sampler, |
| | int lod); |
ivec3 textureSize( | gsampler3D sampler, |
| | int lod); |
ivec2 textureSize( | gsamplerCube sampler, |
| | int lod); |
ivec2 textureSize( | sampler2DShadow sampler, |
| | int lod); |
ivec2 textureSize( | samplerCubeShadow sampler, |
| | int lod); |
ivec3 textureSize( | gsampler2DArray sampler, |
| | int lod); |
ivec3 textureSize( | sampler2DArrayShadow sampler, |
| | int lod); |
Parameters
sampler
Specifies the sampler to which the texture whose dimensions to retrieve is bound.
lod
Specifies the level of the texture for which to retrieve the dimensions.
Description
textureSize returns the dimensions of level lod (if present)
of the texture bound to sampler. The components in the return value are filled in,
in order, with the width, height and depth of the texture. For the array forms, the last component of the
return value is the number of layers in the texture array. The return values are returned as highp ints.
