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.

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

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

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

Promptly finalizes the resource.

This can be unsafe; see finalizeNow.

Instances

OpenGLResource GLsync Fence

OpenGLResource GLuint Buffer

OpenGLResource GLuint Texture

If you use finalize, be careful of any resource that might refer to the texture.

OpenGLResource GLuint Framebuffer

OpenGLResource GLuint Pipeline

Despite the Haskell name, Pipeline, the object is a shader program object.

OpenGLResource GLuint Shader

OpenGLResource GLuint VAO

OpenGLResource a (WrappedOpenGLResource a)

OpenGLResource GLuint (Query a)
