Public Attributes
bool	degenerated
	The surface geometry is positionally degenerated if true.
Math::Vec3	p
	Intersection point.
Math::Vec3	gn
	Geometry normal.
Math::Vec3	sn
	Shading normal.
Math::Vec3	ss
Math::Vec3	st
	Tangent vectors w.r.t. shading normal.
Math::Vec2	uv
	Texture coordinates.
Math::Mat3	worldToShading
	Convarsion to local shading coordinates from world coordinates.
Math::Mat3	shadingToWorld
	Convarsion to world coordinates from local shading coordinates.

Detailed Description

Surface geometry. Contains geometry information of a point on the scene surfaces. Normals and tangents are defined only if the surface geometry at p is not degenerated. TODO : Use unrestricted unions in the future implementation.

Member Function Documentation

LM_FORCE_INLINE void SurfaceGeometry::ComputeTangentSpace ( )

inline

Compute tangent space w.r.t. shading normal. Computes sn, sn, worldToShading and shadingToWorld from sn.
