Detailed Description

A viewer may provides its own ValuePool.

The ValuePool may also be shared with some external ValuePool.

Member Function Documentation

virtual bool Wizt::Viewer::initializeContext

(

VRenderContext &

VRC

)

[pure virtual]

Make all render objects visible in this viewer.

Initialize a VRenderContext with viewer-specific settings; this function is also supposed to make an OpenGL context current within some window manager environment (X11 or Windows call).

bool Wizt::Viewer::render	(	VRenderContext &	Context,
		int	MinLevel = RENDER_FIRST,
		int	MaxLevel = RENDER_LAST
	)			const

Render the entire scene.

Parameters:

	Context	The render context
	MinLevel	The start layer of object categories to be rendered
	MaxLevel	The end layer of object categories to be rendered
