data Texture Source

Constructors

Texture
Fields resource :: !(Resource Texture_) ordIndex :: !Unique viewSpecification :: !TextureSpecification

Instances

Eq Texture Source
Ord Texture Source
OpenGLResource GLuint Texture Source	If you use `finalize`, be careful of any resource that might refer to the texture.

newtype Texture_ Source

Constructors

Texture_ GLuint

type TextureUnit = Int Source

The type of a texture unit.

The minimum valid value is 0 and maximum is implementation dependant but in OpenGL at least 48 units will work at the same time in shaders.

data TextureSpecification Source

Specification on what the texture should be like.

Use textureSpecification and set at least topology and imageFormat. Future minor versions remain compatible if you use textureSpecification instead of the constructor directly.

Constructors

TextureSpecification
Fields topology :: Topology imageFormat :: ImageFormat mipmapLevels :: Int How many mipmap levels including the base level? Must be at least 1. Ignored and not evaluated for multisampling textures.

Instances

Eq TextureSpecification Source

data Topology Source

Specifies a topology of a texture.

withBinding :: (MonadIO m, MonadMask m) => GLenum -> GLenum -> GLuint -> m a -> m a Source

bindingQueryPoint :: GLenum -> GLenum Source

Given a bind location (such as GL_TEXTURE_3D), returns the query enum that retrieves the current binding from glGetIntegerv (such as GL_TEXTURE_BINDING_3D).

getTopologyBindPoints :: Topology -> (GLenum, GLenum) Source

withBindingByTopology :: (MonadIO m, MonadMask m) => Texture -> (GLenum -> m a) -> m a Source

withTextureBinding :: (MonadIO m, MonadMask m) => Texture -> TextureUnit -> m a -> m a Source
