Documentation
A state monad on top of GL.
Arguments
| :: (BackendIO, GLES) | |
| => Int | Viewport width |
| -> Int | Viewport height |
| -> Canvas | Canvas |
| -> GL DrawState |
Create a DrawState.
removeGeometry :: (GLES, BackendIO) => Geometry is -> Draw Bool Source
Delete a Geometry from the GPU.
removeProgram :: (GLES, BackendIO) => Program gs is -> Draw Bool Source
Delete a Program from the GPU.
textureUniform :: (GLES, BackendIO) => Texture -> Draw ActiveTexture Source
This helps you set the uniforms of type Sampler2D.
textureSize :: (GLES, BackendIO, Num a) => Texture -> Draw (a, a) Source
Get the dimensions of a Texture.
renderLayer :: BackendIO => RenderLayer a -> Draw (a, [Texture]) Source
Realize a RenderLayer. It returns the list of allocated Textures so
that you can free them if you want.
Arguments
| :: (GLES, BackendIO, Integral a) | |
| => [LayerType] | Textures contents. |
| -> a | Width |
| -> a | Height |
| -> Layer | Layer to draw |
| -> Either b ([Color] -> Draw b, Int, Int, Int, Int) | Color inspecting function, start x, start y, width, height |
| -> Either c ([Word8] -> Draw c, Int, Int, Int, Int) | Depth inspecting, function, etc. |
| -> Draw ([Texture], b, c) |
Draw a Layer on some textures.
