ABSTRACT: The problem of real-time photorealistic imaging is discussed. New
techniques for specifying free forms without their approximation by polygons
are considered. Free
forms based on the perturbation functions have an advantage
of spline representation of surfaces, that is, a high degree of smoothness, and
an advantage of arbitrary form for a small number of perturbation functions.
Transformations of geometric objects are described for set-theoretic
operations, projections, offsetting, and metamorphosis. We propose a GPU solution to render freeform objects at high frame rates.
