OpenGL State Helper

group FnGLStateHelper

Enums

enum Bit

Each client is responsible for setting up their own renderstate before submitting draw jobs. Often a client will need to temporarily change state for their purpose. The purpose of GLStateRestore is to provide a RAII mechanism to do this. The various bits to restore.

Values:

enumerator Enable

enumerator AccumuBuffer

enumerator ColorBuffer

enumerator Current

enumerator DepthBuffer

enumerator Eval

enumerator Fog

enumerator Hint

enumerator Lighting

enumerator Line

enumerator List

enumerator Multisample

enumerator PixelMode

enumerator Point

enumerator Polygon

enumerator PolygonStipple

enumerator Scissor

enumerator StencilBuffer

enumerator Texture

enumerator Transform

enumerator Viewport

enum Binding

Bindings to unbind on destruction.

Values:

enumerator UnbindArrayBuffer

enumerator UnbindTexture

enumerator UnbindVertexArray

enumerator UnbindProgram

enumerator UnbindAll

class GLStateRestore

#include <FnGLStateHelper.h>

Provide a RAII mechanism to temporarily change the OpenGL state.

Public Functions

inline explicit GLStateRestore(GLbitfield mask, Bindings bindings = 0): Constructor. mask should be any combination of the Bit enumeration values.
