Member Function Documentation

void Render::Initialize	(	boost::shared_array< unsigned char >	dataPtr,
		int	texWidth,
		int	texHeight,
		int	texDepth,
		boost::shared_array< float >	transferFunctionPtr,
		int	transferFunctionWidth,
		float	step,
		int	stepNumber,
		const Matrix4x4 &	viewMatrix,
		const Matrix4x4 &	volumeMatrix,
		const Vector3 &	bboxMin,
		const Vector3 &	bboxMax
	)

Loads a default opengl configuration.

Parameters:

	width	render window width
	height	render window height

Note:

It's very ugly to have a separete method for initialization and don't use the constructor.

TODO Check CUDA capabilities

void Render::Reshape	(	int	width,
		int	height
	)

Reshapes opengl viewport and initialize states.

Parameters:

	width	render window width
	height	render window height
