nurbspy.nurbs_surface_revolution module

class nurbspy.nurbs_surface_revolution.NurbsSurfaceRevolution(generatrix, axis_point, axis_direction, angle_start, angle_end)

Bases: object

Create the NURBS surface obtained by revolving a generatrix NURBS curve C(u) about an axis

Parameters:

generatrixNURBS curve object

See NurbsSurface class documentation

axis_pointndaray of with shape (3,)

Point that together with a direction defines the axis of rotation

axis_directionndarrays with shape (3,)

Direction that together with a point defines the axis of rotation

theta_startscalar

Start angle, measured with respect to the generatrix

theta_endscalar

End angle, measured with respect to the generatrix

Methods

intersect_lines(P0, T0, P2, T2)	Compute the point of intersection between two lines in 2D or 3D
make_nurbs_surface()	Make a NURBS surface representation of the revolution surface
project_point_to_line(S, T, P)	Compute the projection of a point P into the line given by S + u*T
