I updated our application to Java3D 1.2, and the beautiful transparency (illustrating intersecting objects) that worked great in Java3D 1.1.3 went -- pardon the technical jargon -- all higgledy-piggledy. Some shapes were rendered in solid colors, and some in non-expected orders. I'm using lightin

The scene is not loaded live. Before you attach it to the live scene make your adjustments. If you will want to be modifying attributes after the scene is live make sure you set the capability bits. I routinely change materials and so forth to objects loaded in OBJ files. Dave > -- >

Mark, I think I see what you are saying. Don't use the lookAt on the geometries, instead use it on the camera. I've included a snippet of some of my code to let you see. My code places the camera a position in the world and has it look at a point. I then uses the KeyboardNavigator to allow

Mark, Get the view platform TransformGroup with a line like: TransformGroup vpTrans = simpleU.getViewingPlatform().getViewPlatformTransform(); Then translate it to move it, and use rotate to turn your view with code like this: T3Dtemp.rotY(angle); T3Dtemp2.rotX(pitch); T3D.mul(T3Dtemp,T3

Sure, I do this in my application. Ideally you should be able to use the alpha channel of a texture to let you do this, though I was not successful using an SGI RGBA image file on the Win32 platform with JDK 1.3 and J3D 1.2.1 (D3D) or J3D 1.2 (OGL). Therefore I assign the texture to a polygon

Shaun, thanks for the response My idea here is to let the geometry sit still while I move my view point (all ways looking at 0,0,0) around the object. I want to start by moving my 'point of view' to each of the axis. Given your advice, which Transform3D object would I use to call the method (

You could just do a p1.distance(p2) where p1 is your location and p2 is the location of the tree. But have you tried to use ordered groups for this yet? To my knowledge you cannot swap the children of an ordered group around, you have to detach them and rebuild the array. I have been building
