Re: [JAVA3D] Shadows

does anyone happen to have the source code that generates these real time shadows?     ----- Original Message ----- From: Alessandro Borges To: [EMAIL PROTECTED] Sent: Monday, June 30, 2003 2:31 PM Subject: Re: [JAVA3D] Shadows There is some demos available below, but I am not sure if it will fit you needs: http://forum.java.sun.com/thread.jsp?forum=21&thread=330689 http://mightymarine.topcities.com/dynamicshadows.html http://mightymarine.topcities.com/staticshadows.html   A possibilty of working  shadows is by using projective textures see:  http://developer.nvidia.com/view.asp?IO=Projective_Texture_Mapping   I am still  learning how to make this work on Java3D.... Up to now I discover I have to generate TEXTURE_COORDINATE_4 and apply some transforms over the (projective) texture :-D   Alessandro ----- Original Message ----- From: Young, Jason To: [EMAIL PROTECTED] Sent: Monday, June 30, 2003 2:34 PM Subject: Re: [JAVA3D] Shadows Java3D tutorial section 6.7.2: "The complexity of computing shadows is so great it is not part of any real-time graphics system" So no, shadows are not supported directly HOWEVER there are things you can do to create your own shadows. Read the tutorial chapter 6, that may shed some light on things (pun intended) :) -----Original Message----- From: Zak Nixon [mailto:[EMAIL PROTECTED] Sent: Monday, June 30, 2003 12:58 PM To: [EMAIL PROTECTED] Subject: [JAVA3D] Shadows Can shadows be implemented in Java3D? Are they currently?   For instance, I have a sun, earth, and satellites. If the satellites pass to the "non-sunlit" portion of the earth, will they act as if their is no light source present, and color theirselves accordingly?   Thanks   Zak
