chrono::ChSurface Class Reference
Description
Base class for all geometric objects representing bi-parametric surfaces in 3D space.
This is the base for all U,V-parametric object, implementing Evaluate() that returns a point as a function of two U,V parameters.

Member Function Documentation
◆ Evaluate()
|
inlinevirtual |
"Virtual" copy constructor (covariant return type).
Return a point on the surface, given parametric coordinates U,V. Parameters U and V are always in the [0,1] range. The default implementation always returns the origin of the surface frame.
Reimplemented in chrono::ChSurfaceNurbs.
◆ GetManifoldDimension()
|
inlinefinaloverridevirtual |
Return dimensionality of this object.
For a surface, this is always 2.
Reimplemented from chrono::ChGeometry.
◆ GetNormal()
|
virtual |
Return the normal unit vector at the parametric coordinates (U,V).
Parameters U and V are always in the [0,1] range.
