Re: [JAVA3D] transparent Canvas3D

[David Yazel]

Well perhaps the question is "what to expect to see behind the canvas?"  If you want to see other components either Swing or AWT then I think Joachim already answered that.  If you want to see color other than black then you can set the background color.  I think the answer you are looking for is no, you can't do that you want to do.  OpenGL and DirectX need a retangular raster to draw to, and they fill the whole thing up.  Technically you could render to an offscreenbuffer, mask out the background using the zbuffer and write it into a lightweight component.  Course it would be slow as molasses, and in slow I mean 2-20 seconds a frame.   Dave Yazel www.cosm-game.com ----- Original Message ----- From: zero To: [EMAIL PROTECTED] Sent: Thursday, May 31, 2001 4:56 AM Subject: Re: [JAVA3D] transparent Canvas3D hi again,   perhaps i explained my problem not exactly enough.   in java3d (and i guess it comes from OpenGL/DirectX) the canvas3D is rendered black, though there are no objects/background, but i need it transparent to see whats behind it.. so does anyone knows if it is possible to change the background to be transparent or not ? - may be not because of the limitation in OpenGL/DirectX ?   greetings Michael Nischt ----- Original Message ----- From: zero To: [EMAIL PROTECTED] Sent: Wednesday, May 30, 2001 2:55 PM Subject: [JAVA3D] transparent Canvas3D hi there, i wonder, whether it is possible to create a canvas3D which is transparent, for creatinge an application, where a character can walk around in over other components....   the special case: at my university they are working on a project with an animated gif character in a JPanel, and they are thinking of exchanging their character with a 3D one, so i need to know if s.th. like that is possible in Java3D..     thanks a lot for answering Michael Nischt
