texel_type texture_lod(normalized_type const &SampleCoord, size_type Face, level_type Level) const
Sample the sampler texture at a specific level.
Namespace where all the classes and functions provided by GLI are exposed.
Definition: comparison.hpp:15
filter
Texture filtring modes.
Definition: filter.hpp:18
void generate_mipmaps(filter Minification)
Generate all the mipmaps of the sampler texture from the texture base level.
void texel_write(extent_type const &TexelCoord, size_type Face, size_type Level, texel_type const &Texel)
Write a texel in the sampler texture.
Genetic sampler class.
Definition: sampler.hpp:33
Cube map texture sampler.
Include to use wrap modes and the sampler base class.
texture_type const & operator()() const
Access the sampler texture object.
wrap
Texture coordinate wrapping mode.
Definition: sampler.hpp:11
Cube map texture.
void clear(texel_type const &Texel)
Clear the sampler texture with a uniform texel.
Include to use cube map textures.
texel_type texel_fetch(extent_type const &TexelCoord, size_type Face, size_type Level) const
Fetch a texel from the sampler texture.
