ColorBuffer

DepthBuffer

StencilBuffer

data Layer

An Object associated with a program.

layer :: (Subset progAttr grpAttr, Subset progUni grpUni) => Program progUni progAttr -> Object grpUni grpAttr -> Layer

Create a simple Layer from a Program and an Object.

over :: Layer -> Layer -> Layer infixl 1

Draw the first Layer over the second one. This means that the first Layer will use the same buffers (color, depth, stencil) of the second, but the visibility of the objects still depends on their depth.

clear :: [Buffer] -> Layer -> Layer

Clear some buffers before drawing a Layer.
