Abstract:
In this paper we give an overview of our research on nonphotorealistic
rendering methods for computer-generated pencil
drawing. Our approach to the problem of simulating pencil drawings
was to break it down into the subproblems of (1) simulating
first the drawing materials (graphite pencil and drawing paper,
blenders and kneaded eraser), (2) developing drawing primitives
(individual pencil strokes and mark-making to create tones and textures),
(3) simulating the basic rendering techniques (outlining and
shading of 3D models) used by artists and illustrators familiar with
pencil rendering, and (4) implementing the control of drawing steps
from preparatory sketches to finished rendering results. We demonstrate
the capabilities of our approach with a variety of images generated
from reference images and 3D models.
