chrono::geometry::ChVolume Class Referenceabstract

Description

Base class for all geometric objects representing tri-parametric surfaces in 3D space.

This is the base for all U,V,W-parametric object, implementing Evaluate() that returns a point as a function of three U,V,W parameters.

virtual void chrono::geometry::ChVolume::Evaluate ( ChVector<> &  pos,
const double  parU,
const double  parV,
const double  parW 
) const
pure virtual

"Virtual" copy constructor (covariant return type).

Evaluates a point in the volume, given parametric coordinates U,V,W. Parameters U V W always work in 0..1 range. Computed value goes into the 'pos' reference. It must be implemented by inherited classes.

Implemented in chrono::geometry::ChRoundedBox, and chrono::geometry::ChBox.
