# Filename : sketchy_multiple_parameterization.py
|
|
# Author : Stephane Grabli
|
|
# Date : 04/08/2005
|
|
# Purpose : Builds sketchy strokes whose topology relies on a
|
|
# parameterization that covers the complete lines (visible+invisible)
|
|
# whereas only the visible portions are actually drawn
