How have people dealt with the need to attach and detach branch groups without causing memory issues? I am not detecting any leaking, but I could be missing it. But my memory runtime increases steadily up to 200mb over a 20 minute run. Calling garbage collection might be the solution, but it a

[JAVA3D] Perceived distance and size mystery

We have been noticing something strange. Virtual distances seem closer than they really are. For example if we have the user's eye at 1.7 meters from the ground and there is an object 5 meters away, it looks like you are on top of it practically. I went into everquest (a 3d commercial world) an

Re: [JAVA3D] Perceived distance and size mystery

As an update, if I double the field of view to PI/2 instead of PI/4 distances look correct, but that introduces a fishbowl situation, since to see that much requires nasty bending. Still can't fugure this out. - Original Message - From: David <[EMAIL PROTECTED]> To: <[E

Re: [JAVA3D] How to REALLY get humanoid content into a Java 3D application?

There are a few people here with real-world experience, and they are probably all different experiences :) www.roboforge.com is an application using Java3d and has quite nice animation. You can bring a non-animated humanoid into Java3d very easily using Starfire Lab's 3ds loader. I would stay a

Re: [JAVA3D] Pb with texture on SGI

You did not set the TransparencyAttributes for the shape, and you didn't define vertex colors. Thats probably part of the problem. Dave Yazel - Original Message - From: Gatien Mellion <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, January 17, 2001 4:11 AM Subject: [JAVA3D]

Re: [JAVA3D] where to find a simple example of java 3D (not very simple but a bit difficult as arm or a robot ...)

There are a large number of sample programs in the java3d development kit. You can also download the application programming interface documentation from the sun site. In the package javax.media.j3d package you will find the class Transform3D. In this class there is the method lookAt(). I don't
