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()
|
pure virtual |
"Virtual" copy constructor (covariant return type).
Evaluates a point on the surface, given parametric coordinates U,V. Parameters U and V always work in 0..1 range. Computed value goes into the 'pos' reference. It must be implemented by inherited classes.
Implemented in chrono::geometry::ChSurfaceNurbs.
◆ Normal()
|
virtual |
Evaluates a normal versor, given parametric coordinates U,V.
Parameters U,V always work in 0..1 range. Computed value (normalized) goes into the 'pos' reference. It could be overridden by inherited classes if a precise solution is known (otherwise it defaults to numerical BDF using the Evaluate() function).
The documentation for this class was generated from the following files:
