chrono::geometry::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 always work in 0..1 range. The default implementation always returns the origin of the surface frame.
Reimplemented in chrono::geometry::ChSurfaceNurbs.
◆ GetNormal()
|
virtual |
Return the normal unit vector at the parametric coordinates U,V (in the range [0,1]).
Computed value (normalized) goes into the 'pos' reference. This default implementation uses finite differences.
