Additional bug fixes were also done along with the code updates: * Fix for the use of old Interface1D.pointsBegin() and .pointsEnd() method names in the definition of pyDensityAnisotropyF1D and pyViewMapGradientNormF1D. * Fix for wrong data types (int instead of bool) for: - pyChainSilhouetteGenericIterator constructor and its .orientation property in modules/freestyle/chainingiterators.py. - SpatialNoiseShader constructor in styles/external_contour_sketchy.py. - ChainSilhouetteIterator constructor in styles/multiple_parameterization.py.

|
|
# Purpose : The thickness and the color of the strokes vary continuously
|
|
# independently from occlusions although only
|
|
# visible lines are actually drawn. This is equivalent
|
|
# to assigning the thickness using a parameterization covering
|
|
# the complete silhouette (visible+invisible) and drawing
|
|
# the strokes using a second parameterization that only
|
|
# covers the visible portions.
