Excerpt from An Efficient Approximation for Penumbra Shadow
Ray tracing algorithms generate excellent realistic images, but in general they are compu tationally very expensive. Simple ray tracing has aliasing problems as well. [1] presented a cone tracing technique for anti-aliasing, fuzzy shadows, and dull reflections. To improve the efficiency of ray tracing created a hierarchy of bounding volumes to reduce the number. Of bounding volume intersection checks; employed 3d space subdivision in culling objects; [12] made use of the coherence which exists between similar rays. Though a certain degree of improvement in efficiency has been attained by the above efforts.

Paperback. Zustand: New. Print on Demand. This book introduces a new method for computer-generated shadows in images. The book places this method within the history of computer graphics, from early point-type light sources to the present, which includes penumbras, or soft shadow edges. The author analyzes the errors that arise from the new method and includes a solution so users can control them. Unlike the more computation-heavy technique of ray tracing, this new method utilizes a modified and efficient Z-buffer technique. This combination of accuracy and efficiency makes this a significant book for readers interested in computer graphics, image generation, and rendering. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
