data Texture Source

Constructors

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

Instances

Eq Texture
Ord Texture
Typeable * 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.

ordIndices :: IORef Int Source

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
Typeable * TextureSpecification

data Topology Source

Specifies a topology of a texture.
