verts may be a list of dictionaries instead of a list of
tuples. In this case, each vertex dictionary may have any of
the following elements:
'node' : the NodePath indicating the coordinate space
'point' : the 3-D point relative to the node; default (0, 0, 0)
'color' : the color of the vertex, default (1, 1, 1, 1)
'thickness' : the thickness at the vertex, default 1
In order to enable the per-vertex color or thickness, you must
call rope.ropeNode.setPerVertexColor() or
rope.ropeNode.setPerVertexThickness().
knots is optional. If specified, it should be a list of
floats, and should be of length len(verts) + order. If it
is omitted, a default knot string is generated that consists
