Abstract:
We present an animatable Painterly Object. We use a volume of occupancy
probabilities to determine where and how paint is applied.
This probability density function approach to modeling gives the
artist control over (and the option of) a painterly style. Probabilities
in the volume are initialized by the modeler and are changed as
paint is applied. Applied paint is stored within the volume so paint
that has been applied remains (in 3D) when neighboring strokes are
made and when the scene is re-rendered (e.g. animation, etc.). The
desired painterly effects can be achieved either natively in 3D or
they can be applied in 2D and stored in 3D. Automated 3D application
of 3D paint to a 3D object is a significant result of this work.
The result is a 3D object that appears painterly and allows pleasing
animation and scene changes along with hybridization of painterly
and non-painterly objects into a single scene without compositing
techniques.
