* Implement GeomEvaluator package * Inject evaluators to GeomAdaptor_Surface to calculate values of complex surfaces * Inject evaluators to Geom_Surface classes to calculate values for offset surfaces, surfaces of revolution and surfaces of extrusion * Move Adaptor3d_SurfaceOfLinearExtrusion and Adaptor3d_SurfaceOfRevolution to GeomAdaptor and unify calculation of their values and derivatives * Code optimizations * Update test cases Update of test-cases according to the new behavior

//! This class defines a complete surface of revolution.
|
|
//! The surface is obtained by rotating a curve a complete revolution
|
|
//! about an axis. The curve and the axis must be in the same plane.
|
|
//! If the curve and the axis are not in the same plane it is always
|
|
//! possible to be in the previous case after a cylindrical projection
|
|
//! of the curve in a referenced plane.
|
|
//! For a complete surface of revolution the parametric range is
|
|
//! 0 <= U <= 2*PI. --
|
|
//! The parametric range for V is defined with the revolved curve.
|
|
//! The origin of the U parametrization is given by the position
|
|
//! of the revolved curve (reference). The direction of the revolution
|
|
//! axis defines the positive sense of rotation (trigonometric sense)
|
|
//! corresponding to the increasing of the parametric value U.
|
|
//! The derivatives are always defined for the u direction.
|
|
//! For the v direction the definition of the derivatives depends on
|
|
//! the degree of continuity of the referenced curve.
