Latest Patents

One of Glassner's latest patents is an image rendering system that utilizes local, adaptive estimation of incident light. This method involves coloring pixels on a pixelated display to simulate images of objects illuminated by light sources. The process defines a space with objects and light sources, taking a viewpoint and dividing the view surface into unit areas corresponding to pixels. The illumination of points on object surfaces is calculated, and a data structure is saved for each point, detailing its location, orientation, and the rays of illumination reaching it. This innovative approach allows for efficient shading without the need to search the entire space for diffuse reflections.

Another notable patent involves methods for converting concave polyhedra to their convex hulls. This technique modifies shapes represented as non-self-intersecting, simply connected, triangulated polyhedra. By performing pop or slide procedures on concave edges, the method results in a visually smooth transformation of the concave shape to its convex hull or other intermediate shapes.
