Regions

data Region r m a

A Region is a monad transformer used to create relationships between two monadic layers and ensure GPU safety.

Instances

MonadTrans (Region k * r)

Monad m => Monad (Region k * r m)

Functor m => Functor (Region k * r m)

Applicative m => Applicative (Region k * r m)

MonadIO m => MonadIO (Region k * r m)

gpuRegion :: Region () m a -> m a

The GPU main Region. This Region is the highest and more general you can find. You’ll need to enter it if you want to enter any GPU specific regions.

newFrame :: MonadIO m => Framebuffer rw c d -> Region Framebuffer m a -> Region () m a

The Framebuffer Region. This Region binds a Framebuffer for all children regions.

newShading :: MonadIO m => Some Program -> Region Program m a -> Region Framebuffer m a

The Program Region. This Region binds a Program for all children regions.

Drawing

drawGeometry :: MonadIO m => RenderCmd rw c d Geometry -> Region Program m ()

Draw the Geometry held by a RenderCmd.
