Bend a straight pipe-like NURBS volume into a circular arc.
Each control point is transformed relative
to the center .
Let the total bend angle in degrees be (input),
and define the total bend angle in radians
For each control point:
Mapping:
Knots and weights are preserved; only the control lattice is updated.
Nodes of different colours represent the following:
Solid arrows point from a procedure to one which it calls. Dashed
arrows point from an interface to procedures which implement that interface.
This could include the module procedures in a generic interface or the
implementation in a submodule of an interface in a parent module.
Where possible, edges connecting nodes are
given different colours to make them easier to distinguish in
large graphs.
