Whole Framebuffer Operations

Clearing the Buffers

clear :: [RenderConfig] -> BufferMask -> GL ()

clear [] colorBuffer
clear [bindFb framebuffer] (colorBuffer+depthBuffer)

clearColor :: Float -> Float -> Float -> Float -> GL ()

clearDepth :: Float -> GL ()

clearStencil :: Int32 -> GL ()

data BufferMask

Instances

Num BufferMask

colorBuffer :: BufferMask

depthBuffer :: BufferMask

stencilBuffer :: BufferMask

Fine Control of Buffer Updates

colorMask :: V4 Bool -> GL ()

depthMask :: Bool -> GL ()

stencilMask :: Word32 -> GL ()

stencilMaskSep :: CullFace -> Word32 -> GL ()

Renderbuffer

glRenderbuffer :: forall a b. InternalFormat a b => Int32 -> GL (V2 Int32) -> GL (Renderbuffer b)

New Renderbuffer with specified sample count and dimentions.

unsafeRenderbuffer :: Int32 -> GL (V2 Int32) -> GLenum -> GL (Renderbuffer a)

Framebuffer

glFramebuffer :: [CR] -> DepthStencil -> GL Framebuffer

New Framebuffer from specified ColorRenderable and DepthStencil

data CR

Constructors

class Attachable a b

Minimal complete definition

glAttachToFramebuffer

Instances

Attachable Texture a

Attachable Renderbuffer a

data DepthStencil

colorOnly :: DepthStencil

depthImage :: (Attachable a d, DepthRenderable d) => a d -> DepthStencil

stencilImage :: (Attachable a s, StencilRenderable s) => a s -> DepthStencil

depthStencil :: (Attachable a r, DepthRenderable r, StencilRenderable r) => a r -> DepthStencil

Framebuffer Settings

bindFb :: Framebuffer -> GL ()

defaultFramebuffer :: Framebuffer

viewport :: V4 Int32 -> GL ()

Cliping current framebuffer. Note that origin is left-bottom.

getViewport :: GL (V4 Int32)

withViewport :: V4 Int32 -> GL a -> GL a

depthRange :: V2 Float -> GL ()

getDepthRange :: GL (V2 Float)

withDepthRange :: V2 Float -> GL a -> GL a
