Implicit painting of CSG solids
Ergün Akleman · 2006
Implicit painting is a non-photorealistic rendering method for painting implicitly represented CSG solids. The method is based on the fact that when a difference equation is ap-plied to a set of particles these particles will move in 3D space. We view the motion of the particles as the motion of the hands of several painters and the trajectories of the par-ticles as long unbroken brush strokes, over the boundaries of solids obtained by set-operations. These boundary surfaces are used as if they are the canvases of painters. The differ-ence equations provide the trajectories of the brushes, brush and paint types. We consider this painting as a creative or ‘artistic ’ process in which the resulting artwork can be an image, a stereo image or even an animation that shows the painting process.
