Classes
class	UniformVariable
	Represents a uniform variable in a shader program. The program must be bound before any values may be set. More...
class	ShaderCode
	Represents source and compiled shader code pieces. More...
class	ShaderProgram
	Represents a shader program. More...
class	AutoBindShaderProgram
	Helper to automatically bind a shader program then unbind it when it leaves scope. More...
struct	TextureDimensions
	Represents the dimensions of a texture. More...
struct	TextureCreateParameters
	Parameters used in the creation of a texture. More...
class	TextureBase
	Base class for the other texture classes. More...
class	Texture2D
	Represents a two dimensional texture. More...
class	AutoBindTexture
	Helper to automatically bind a texture then unbind it when the scope ends. More...
struct	TextColor
	Represents a text color change. More...
class	EncodedText
	Text encoded with color information. More...
class	TextWriter
	Generates and renders a transparent texture with opaque text. More...
struct	VertexComponentFormat
	An individual vertex component's use, type, and number of elements. One or more of these are combined to make a InterleavedVertexFormat. More...
struct	InterleavedVertexFormat
	Represents the combination of vertex components. More...
class	VertexBuffer
	Represents a vertex buffer object. More...
class	AutoBindVertexBuffer
	Helper to automatically bind a vertex buffer then unbind it when the scope ends. More...
class	IndexBuffer
	Represents an index buffer object. More...
class	AutoBindIndexBuffer
	Helper to automatically bind an index buffer then unbind it when the scope ends. More...
struct	ScreenSize
	Represents a the size of a window or screen. More...
struct	GraphicsSetup
	Represents the state of graphics system and its related window. Everything in here can be both changed or read from. More...
Enumerations
enum	FontType { VARIABLE_SERIF = 0x0000, VARIABLE_SANSERIF = 0x0001 }
	Style of font. More...
enum	VertexComponentMeaning { VertexPosition, VertexNormal, VertexColor }
	What a component of a stream represents. More...
Functions
GLsizei	GetGLTypeSize (GLenum type)
	Returns the numbere of bytes needed to store a specific opengl data type.
bool	IsExtensionAvailable (const std::string &name)
	Returns whether a specifically named OpenGL extension is present on the current system.
VoidFuncPtrType	GetExtensionFunction (const std::string &name)
	Returns a pointer to a OpenGL extension function with a specific name, or 0 if not found.
bool	SetupWindow (const GraphicsSetup &newState)
	Creates or updates the state of the applications window and sets up OpenGL. Returns true if changing to the specified settings was successful, false if it failed. This must be called at least once before OpenGL can be used. Only the thread that called this to create the window may make OpenGL calls.
void	ShutdownWindow ()
	Closes the window and shuts down the graphics system. This must be called from the same thread that called SetupWindow to create the initial window.
const GraphicsSetup *	GetWindowState ()
	Retrieves the current state of the window, or 0 if not running.
void	UpdateWindow ()
	Handles any window system events, and exposes the backbuffer. You should normally call this every frame. You should check GetWindowState after calling this to verify that the window still exists. This must be called from the same thread that called SetupWindow to create the initial window.
bool	WindowHasFocus ()
	Returns whether the window currently has the user's focus.
ScreenSize	GetCurrentScreenSize ()
	Returns the resolution of the current screen.
GLenum	GetGLError ()
	Returns and dequeues an entry from the OpenGL error queue. Returns GL_NO_ERROR if no errors occured.
void	ClearGLErrors ()
	Clears any OpenGL errors from the error queue.
Variables
bool	VerboseGLErrorsOnGet = true
	This controls whether GetGLError reports all errors to MPMA's error reporting object. Default is true.
