virtual bool primitive_t::clippingSupport

(

)

const [inline, virtual]

indicate if the object has a clipping implementation

Reimplemented in vTriangle_t.

Definition at line 26 of file primitive.h.

virtual bool primitive_t::clipToBound	(	double	bound[2][3],
		int	axis,
		bound_t &	clipped,
		void *	d_old,
		void *	d_new
	)			const [inline, virtual]

calculate the overlapping box of given bound and primitive

Returns:

: false:=doesn't overlap bound; true:=valid clip exists

Reimplemented in vTriangle_t.

Definition at line 29 of file primitive.h.

virtual bound_t primitive_t::getBound

(

)

const [pure virtual]

return the object bound in global ("world") coordinates

Implemented in sphere_t, vTriangle_t, and bsTriangle_t.

virtual const material_t* primitive_t::getMaterial

(

)

const [pure virtual]

Implemented in sphere_t, vTriangle_t, and bsTriangle_t.

virtual void primitive_t::getSurface	(	surfacePoint_t &	sp,
		const point3d_t &	hit,
		void *	userdata
	)			const [pure virtual]

Implemented in sphere_t, vTriangle_t, and bsTriangle_t.

virtual bool primitive_t::intersect	(	const ray_t &	ray,
		PFLOAT *	t,
		void *	userdata
	)			const [pure virtual]

basic ray primitive interection for raytracing. This should NOT skip intersections outside of [tmin,tmax], unless negative. The caller decides wether t matters or not.

Returns:

false if ray misses primitive, true otherwise

Parameters:

t

set this to raydepth where hit occurs

Implemented in sphere_t, vTriangle_t, and bsTriangle_t.

virtual bool primitive_t::intersectsBound

(

exBound_t &

b

)

const [inline, virtual]

a possibly more precise check to find out if the primitve really intersects the bound of interest, given that the primitive's bound does. used e.g. for optimized kd-tree construction

Reimplemented in sphere_t, and vTriangle_t.
