chrono::ChVolume Class Referenceabstract


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.

◆ Evaluate()

virtual ChVector3d chrono::ChVolume::Evaluate ( double  parU,
double  parV,
double  parW 
) const

Return a point in the volume, given parametric coordinates U,V,W.

Parameters U, V, and W are always in the [0,1] range. The default implementation always returns the volume center.

Reimplemented in chrono::ChEllipsoid, chrono::ChRoundedBox, chrono::ChBox, chrono::ChSphere, chrono::ChCapsule, chrono::ChCone, chrono::ChCylinder, and chrono::ChRoundedCylinder.

◆ GetManifoldDimension()

virtual int chrono::ChVolume::GetManifoldDimension ( ) const

Return dimensionality of this object.

For a volume, this is always 3.

Reimplemented from chrono::ChGeometry.

◆ GetVolume()

virtual double chrono::ChVolume::GetVolume ( ) const
pure virtual

"Virtual" copy constructor (covariant return type).

Return the volume of this solid.

Implemented in chrono::ChEllipsoid, chrono::ChRoundedBox, chrono::ChSphere, chrono::ChBox, chrono::ChCapsule, chrono::ChCone, chrono::ChCylinder, and chrono::ChRoundedCylinder.
