Detailed Description

template<VEX_Precision PREC>
class GEO_ImplicitBasicSurface< PREC >

Basic Implicit Surface - unified wrapper for elementary implicit surfaces. This class stores transform (position, orientation) and shape parameters, dispatching to the appropriate SDF based on shape ID.

Typically initialized from geometry point attributes: P, orient, shape_parms, shape_id, shape_invert

GEO_ImplicitBasicSurface< PREC >::GEO_ImplicitBasicSurface	(	const char *	name,
		const VEXvec3< PREC > &	P,
		const VEXmat3< PREC > &	transform,
		const VEXvec4< PREC > &	shapevals
	)

Make basic shape fron its name, position, transform and parameters

The transform does not have to be rotation matrix. Scales are extracted and applied to parameters Any shearing or non-uniform scaling is ignored

UT_IntervalT<VEXfloat<PREC> > GEO_ImplicitBasicSurface< PREC >::evalInterval ( const UT_BoundingBoxT< VEXfloat< PREC >> & P ) const

Evaluate SDF bounds for interval box (world space)

UT_IntervalT<VEXfloat<PREC> > GEO_ImplicitBasicSurface< PREC >::evalInterval	(	const VEXvec3< PREC > &	center,

	)		const

Evaluate SDF bounds for bounding sphere (world space). Cheaper than evalInterval when P comes from a rotated region, since transforming a sphere to local space only rotates the center.
