Detailed Description

The RenderSystem class is an abstract base class for a graphics rendering class. It abstracts rendering of graphics from the rest of the engine.

---

Member Enumeration Documentation

enum green::RenderSystem::Graphic

TEMPORARY This enumerates different types of built-in objects to draw.

Constructor & Destructor Documentation

virtual green::RenderSystem::~RenderSystem

(

)

[inline, virtual]

Default destructor declared virtual

---

Member Function Documentation

virtual void green::RenderSystem::Init

(

)

[inline, virtual]

Initialize the RenderSystem

virtual void green::RenderSystem::StartFrame

(

)

[inline, virtual]

StartFrame is called before other rendering commands are called to prepare the frame. For example, this might be implemented to clear the frame or reset graphics flags to their default values, etc..

Reimplemented in green::GLRenderSystem.

virtual void green::RenderSystem::FinishFrame

(

)

[inline, virtual]

FinishFrame is called after other rendering commands are called to finish drawing the frame and perform other post processing. It also waits for async. rendering commands to finish before continuing.

Reimplemented in green::GLRenderSystem.

virtual void green::RenderSystem::DrawObject	(	Graphic	object,
		double	x,
		double	y,
		double	rot
	)			[inline, virtual]

TEMPORARY DrawObject is a temporary method to draw a specific kind of object at a certain location with a certain rotation. In the future this will be replaced by more sophisticated methods.

Reimplemented in green::GLRenderSystem.

virtual void green::RenderSystem::SetColor	(	double	r,
		double	g,
		double	b,
		double	a
	)			[inline, virtual]

Set the draw color.

Parameters:

	r	The red component of the color
	g	The green component of the color
	b	The blue component of the color
	a	The alpha component of the color

virtual void green::RenderSystem::SetClearColor	(	double	r,
		double	g,
		double	b,
		double	a
	)			[inline, virtual]

Set the Clear color, ie the background color.

Parameters:

	r	The red component of the color
	g	The green component of the color
	b	The blue component of the color
	a	The alpha component of the color

virtual void green::RenderSystem::Reshape	(	int	width,
		int	height
	)			[inline, virtual]

This function is called when the viewport changes

Parameters:

	width	The new width of the window
	height	The new height of the window

Reimplemented in green::GLRenderSystem.
