[JAVA3D] offscreen rendering

Hi, I am trying to do offscreen rendering in Java3d 1.2 alpha. The following exception is thrown when I set the offscreen flag to true in the Canvas3D constructor: java.lang.NullPointerException: at javax.media.j3d.VirtualUniverse.enableKeyEvents(VirtualUniverse.java: 432) at

Re: [JAVA3D] A good example of dynamic scene changes

Andy, I guess I want to change the scene on the fly. I have included a quick demo of what I am trying to do. It is a demo that displays three strings of text. The user can change and update the text by clicking a button. thanks again for any help or suggestions. Steve At 11:44 AM 12/10/99 -

Re: [JAVA3D] help setting direction

Hi Wayne, this sounds like you're doing your transformations in the local coordinate system of the object. If you want to let move things in another coordinate system, you first have to perform a coord. transformation. for example tranform your object into the CS of your viewpoint, apply navigati

Re: [JAVA3D] A good example of dynamic scene changes

Dan/Steve, As far as I know there is no way of changing the geometry within a Text3D after it has been created. The setString method will merely *append* geometry to the internal GeometryArray, regardless of what is passed in. SUN were supposed to revise some of the Text3D methods for 1.2 howeve

Re: [JAVA3D] java3d-Books

I beg to differ about this book. I think it is pretty bad. They seemed to have been in a big rush to get it to press. There are numerous mistakes an I stopped reading it after a few chapters. I was especially disappointed by the mistake for the rotation matrices in Chapter 2. All three of the

Re: [JAVA3D] A good example of dynamic scene changes

Steve, Can you be more specific with the problem? Is it that you do not know how to physically change shapes on the scene graph, or are you having problems changing the scene on the fly (as a function of time)? Andy -Original Message- From: Steve Sampson <[EMAIL PROTECTED]> To: [EMAIL

Re: [JAVA3D] java3d-Books

Title: RE: [JAVA3D] java3d-Books I found this book to be almost worthless.  *Far* too much code.  Far too little "simple" code segments explaining of to use Java 3D classes. To learn anything, the authors expect you to review *many* pages of code. I found the tutorial much better to lea

Re: [JAVA3D] java3d-Books

Hi, Other than the API reference by Sun (published by Addison Wesley), the only other book I know of on the subject is "Ready-to-Run Java 3D" by Kirk Brown and Daniel Peterson (Wiley Computer Publishing, New York, 1999, ISBN 0-471-31702-0). Online, look at the Sun site and several others that

Re: [JAVA3D] [Java3D]gc

Hi, that's what I found out too :( IMHO one cannot force gc to run at a predefined time. system.gc() is only a suggestion as you said. If you are using hotspot, try running it in "classic" mode. this will work more smooth. Gernot [EMAIL PROTECTED] mark rudolph

[JAVA3D] [Java3D]gc

Even very simple animations look jittery to me. Perhaps this is the result of garbage collection during frame rendering, or in too big time segments no matter where they occur. Is it possible to force gc to occur only during a limited period of the postswap? I don't think System.gc() actually runs
