Description:
|
Returns an upper limit to the maximum distance from a point to that part of the
bs3_surface whose vertices have parameter values between the given edge and the given value. If
v_param_line is true, then the
u values of the vertices' effective knot values are checked to make sure that they lie between the low/hi
u edge (depending on whether
from_hi is
TRUE/FALSE) and the given (u) param value.
|
|
|
Limitations:
|
This function will give poor estimates if the knot vector or control point distribution is skewed.
