Member Function Documentation

float Bial::Shape::Area ( ) const

Area calculates the surface Area.

Returns: surface area.

virtual bool Bial::Shape::CanIntersect ( ) const

virtual

CanIntersect indicates that a shape can compute ray intersections, so only shapes that are nonintersectable need to override this method.

Returns

Reimplemented in Bial::TriangleMesh.

virtual void Bial::Shape::GetShadingGeometry	(	const Transform3D &	obj2world,
		const DifferentialGeometry &	dg,
		DifferentialGeometry *	dgShading
	)		const

virtual

GetShadingGeometry.

Parameters

obj2world
dg
dgShading

Reimplemented in Bial::Triangle.

virtual bool Bial::Shape::Intersect	(	const Ray &	ray,
		float *	tHit,
		float *	rayEpsilon,
		DifferentialGeometry *	dg
	)		const

virtual

Intersect returns geometric information about a single rayshape intersection corresponding to the first intersection, if any, in the [mint, maxt] parametric range along the ray.

Parameters

ray
tHit
rayEpsilon
dg

Returns

Reimplemented in Bial::Triangle.

virtual bool Bial::Shape::IntersectP ( const Ray & ray ) const

virtual

IntersectP is a predicate function that determines whether or not an intersection occurs, without returning any details about the intersection itself.

Parameters

ray

Returns

virtual BBox Bial::Shape::ObjectBound ( ) const

pure virtual

ObjectBound is the shape bounding box.

Returns

Implemented in Bial::Triangle, and Bial::TriangleMesh.

template<class O >

Print assings Shape information to stream.

Parameters

os	an output stream.

Definition at line 356 of file DrawShape.hpp.

virtual void Bial::Shape::Refine ( Vector< std::shared_ptr< Shape > > & refined ) const

virtual

Refine is a method that splits the shape into a group of new shapes, some of which may be intersectable and some of which may need further refinement.

Parameters

refined
