Function Documentation

virtual void GraphicsInterface::illuminate	(	ray &	r,
		intersection &	inter,
		vec3 &	light_value
	)			[pure virtual, inherited]

Computes direct illumination.

Parameters:

	r	the original ray,
	inter	the intersection in wihich we want the local illumination,
	light_value	the resulting illumination value.

virtual bool GraphicsInterface::search_intersection	(	ray &	r,
		graphics_data_t &	gdata
	)			[pure virtual, inherited]

Searchs for the nearest intersection.

Parameters:

	r	the ray to test,
	gdata	the exchange structure.

Returns:

true if an intersection is found.
