Detailed description

This class provides utilities to view a VTL-mesh, i.e. a collection of mesh-based VTLs. Particularly, it provides methods to sample a given VTL, and methods to locate/map a VTL from a given mesh point.

◆ map()

FERMAT_HOST_DEVICE uint32 VTLMeshView::map	(	const uint32_t	prim_id,
		const cugar::Vector2f &	uv,
		const VertexGeometry &	geom,
		float *	pdf,
		Edf *	edf
	)		const

inline

map a (prim,uv) pair and its surface element to the corresponding VTL/EDF/pdf NOTE: the returned pdf here is only relative to the VTL, i.e. it doesn't account for the probability of sampling that VTL, since the sampling policy is not controlled by this class and intentionally left outside of it.

◆ sample()

FERMAT_HOST_DEVICE void VTLMeshView::sample	(	const uint32	vtl_idx,
		const cugar::Vector2f	vtl_uv,
		uint32_t *	prim_id,
		cugar::Vector2f *	uv,
		VertexGeometry *	geom,
		float *	pdf,
		Edf *	edf
	)		const

inline

sample a point on a given VTL
