Re: [JAVA3D] How to set the normals of IndexedGeometry

Hi Zhu, How to set the normals of IndexedGeometry ? You can use com.sun.j3d.utils.geometry.NormalGenerator But then you have to build the geometry with GeometryInfo. GeometryInfo gi = new GeometryInfo(GeometryInfo.TRIANGLE_ARRAY) ; gi.setCoordinates(coordinates); gi.setCoordinateIndices(indices

Re: [JAVA3D] centering object and rotation

Hi Mona, Before answering your question, could you say that you want to rotate your object itself, or do you want to rotate the camera around the object? Or Both? David. Mona Wong wrote: > Hi: > > I'm a beginning Java 3D programmer. I've got my scene built and can > view it in my windo

[JAVA3D] Wanted J3D class heirarchy image

Folks, I was trawling through the bowels of j3d.org last night and came across a link to a j3d class heirarchy diagram from Ross Finlayson. The problem is that the image is a) old (probably v1.0) b) corrupted I'd like to get the thing updated to the current 1.2 specification and also show it in

Re: [JAVA3D] Wanted J3D class hierarchy image

Wouldn't this be a good Java3D project. A J3D applet or application which extends the javadoc app to generate a full recursive 3D map when any JAR is passed into it. The 3D map could provide links to HTML javadoc type pages when a class is clicked on. Seems the guys at sun might support this, wh

[JAVA3D] infinite rendering loop

I have a class that extends Canvas3D and overrides the public void renderField(int i) method. In the overriding implementation, there is some immediate mode rendering logic. The code works fine in Java3D 1.1.2 and lower, but in 1.1.3 and 1.2 the code somehow creates a cycle resulting in an infin

Re: [JAVA3D] centering object and rotation

Hi Mona, There is some code which implements the method for rotation around an arbitrary point. Using arbitraryTransform method you can rotate object itself or rotate the camera around the object. I hope it will help. Nick Mona Wong wrote: > Hi: > > I'm a beginning Java 3D programmer.
