class (MonadGL m, GLES) => MonadTexture m

Minimal complete definition

getTexture, getActiveTexturesCount, setActiveTexturesCount, newTexture, unusedTextures

Instances

GLES => MonadTexture (Draw o)

Methods

getTexture :: Texture -> Draw o (Either String LoadedTexture)

getActiveTexturesCount :: Draw o Int

setActiveTexturesCount :: Int -> Draw o ()

newTexture :: Int -> Int -> TextureParameters -> Int -> (Texture -> GL ()) -> Draw o LoadedTexture

unusedTextures :: [LoadedTexture] -> Draw o ()

data Texture

A texture.

Instances

GLES => Eq Texture

Methods

(==) :: Texture -> Texture -> Bool

(/=) :: Texture -> Texture -> Bool

mkTexture

Arguments

:: GLES

=> Int

Width.

-> Int

Height.

-> TextureParameters

-> [[Color]]

List of pixels, one for each level of detail. The first element is the base image level, the second image is half the size of the base, and so on. Use just one level of detail if you don't want mipmaps, or you used True in the previous argument.

-> Texture

Creates a Texture from a list of pixels.

mkTextureFloat

Arguments

:: GLES

=> Int

Width.

-> Int

Height.

-> TextureParameters

-> [Vec4]

List of vectors.

-> Texture

Creates a float Texture from a list of vectors.

mkTextureRaw

Arguments

:: GLES

=> Int

Width.

-> Int

Height.

-> TextureParameters

-> [UInt8Array]

Array of pixel components, one for each level of detail.

-> Int

Hash of the arrays

-> Texture

colorTex :: GLES => Color -> Texture

Generate a 1x1 texture.

Parameters

data TextureParameters

Instances

Eq TextureParameters

Methods

(==) :: TextureParameters -> TextureParameters -> Bool

(/=) :: TextureParameters -> TextureParameters -> Bool

Hashable TextureParameters

Methods

hashWithSalt :: Int -> TextureParameters -> Int

hash :: TextureParameters -> Int

data Filter

Constructors

Linear

Average of the four nearest pixels.

Nearest

Nearest pixel.

Instances

Eq Filter

Methods

(==) :: Filter -> Filter -> Bool

(/=) :: Filter -> Filter -> Bool

Hashable Filter

Methods

hashWithSalt :: Int -> Filter -> Int

hash :: Filter -> Int

data WrappingFunction

Constructors

Repeat

MirroredRepeat

ClampToEdge

Instances

Eq WrappingFunction

Methods

(==) :: WrappingFunction -> WrappingFunction -> Bool

(/=) :: WrappingFunction -> WrappingFunction -> Bool

Hashable WrappingFunction

Methods

hashWithSalt :: Int -> WrappingFunction -> Int

hash :: WrappingFunction -> Int

parameters

Arguments

:: Filter

Minification filter

-> Filter

Magnification filter

-> TextureParameters

Create a TextureParameters.

potParameters

Arguments

:: (Filter, Maybe Filter)

Minification filter.

-> Filter

Magnification filter.

-> Bool

Generate mipmaps automatically.

-> WrappingFunction

Horizontal wrapping function.

-> WrappingFunction

Vertical wrapping function.

-> TextureParameters

This function provides more features than parameters, but, on WebGL, the resulting TextureParameters will not work with textures whose width or height is not a power of two.

potLinear

Arguments

:: Bool

Generate mipmaps

-> TextureParameters

potParameters with linear filters and repeat.
