Abstract:
In this paper we present a blender and eraser model
that extends our graphite pencil and paper model. This
blender and eraser model enhances the rendering results
producing realistic looking graphite pencil tones and textures.
Our model is based on observations on the absorptive
and dispersive properties of blenders and erasers interacting
with lead material deposited over drawing paper.
The parameters of our model are the particle composition
of the lead over the paper, the texture of the paper,
the position and shape of the blender and eraser, and the
pressure applied to them. We demonstrate the capabilities
of our approach with a variety of pencil swatches
and compare them to digitized pencil drawings. We also
present automatic and interactive image-based rendering
results implementing traditional graphite pencil tone rendering
methods.
