Member Function Documentation

render()

void st::Framebuffer::render	(	int	x,
		int	y,
		int	width,
		int	height
	)

Renders the framebuffer in the specified screen dymensions.

The framebuffer needs to be set before calling to render. To be called after rendering all other scene elements.

Parameters

width	screen width.
height	screen height.

setFramebuffer()

void st::Framebuffer::setFramebuffer

(

)

Inits the glViewport and the GL_FRAMEBUFFER for the scene objects to be rendered.

To be called at the start of the scene rendering.
