SPAkern Global Function bs2_curve_v_param_line

Creates a parameter line space curve along a v parameter line of a spline surface.

Role: Creates a parameter line space curve along a v parameter line (i. e., one with constant u parameter) of a spline surface.

The v-parameter of the surface varies for this function, while the u-parameter is fixed. The parameterization of the resulting curve is undefined, though it has the same sense as the surface v-parameter, but would normally be the same as the surface v-parameter. The curve will be open, closed, or periodic according to whether the surface was open, closed, or periodic in the v-direction.

Effect: Changes model

Parameters:

v_range

parametric curve range.

form

form of required curve; should correspond to form of surface (object-space meaning rather than parameter-space).

u

u parameter of surface.

This prototype is the preferred way to create the curve.

Effect: Changes model

Parameters:

surf

given surface.

u

u parameter of surface.
