Documentation

class OpenGLResource innertype a | a -> innertype where

All OpenGL resources implement this typeclass.

The resources have an inner type, usually a GLuint but not always.

If you work with raw OpenGL resources, you may need to use touch to make sure the resource is not garbage collected prematurely.

Methods

getRaw :: MonadIO m => a -> m innertype

Returns the raw OpenGL type.

Guarantees that the resource has not been garbage collected at the point this function is invoked.

touch :: MonadIO m => a -> m ()
