Hello: I have no experience in Java 3D and I am planning to learn it to solve an application specific problem. The problem involves an object and a light source (I am planning to use a cone to model the light), and I need to have a yes or no answer whether the light would cover a specified portion of the surface of the object. Can this be done using Java 3D? Thanks. Any comment, advice, and pointers would be greatly appreciated. wing ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com ===================================================================== To subscribe/unsubscribe, send mail to [EMAIL PROTECTED] Java 3D Home Page: http://java.sun.com/products/java-media/3D/
