`nr.c4d.geom`¶

This module provides common heler methods for working with geometry in Cinema 4D, such as computing face- and vertex normals.

Functions¶

nr.c4d.geom.calculate_face_normals(op=None, points=None, polys=None)[source]¶

Builds a list of face normals and polygon midpoints from op or the specified points and polygons lists.

Parameters:	op – `c4d.PolygonObject` points – `list` of `c4d.Vector` polys – `list` of `c4d.CPolygon`
Returns:	(`list` of `c4d.Vector`, `list` of `c4d.Vector`) – The first element is the polygon normals, the second is the polygon midpoint.

nr.c4d.geom.build_point_connection_list(op, nb, polys=None)[source]¶

Builds a list that for each vertex contains a tuple which consists of the indices of points connected with that respective point by an edge in the mesh.

from nr.c4d.geom import build_point_connection_list
from c4d.utils import Neighbor

def main():
  nb = Neighbor()
  nb.Init(op)
  conn = build_point_connection_list(op, nb)
  print "Points connected with point 1:", conn[1]

Parameters:	op – `c4d.PolygonObject` nb – `c4d.utils.Neighbor` initialized with op polys – An optional list of the polygons of op.
Returns:	`list` of `tuple` of `int`
