[JAVA3D] Bug report

In J3d 1.3 beta 1: If you have an alpha blended object which is being sorted by the transparency (not in an ordered group), and that object has geometry which falls outside of view fustrum then the geometry will sometimes be clipped, and sometimes will be rendered without transparency. The bound

Re: [JAVA3D] Change j3d primitive size on fly - possible?

Lan, A quick read of the JavaDoc will show you: void setScale(Vector3d scale) Sets the possibly non-uniform scale component of the current transform; any existing scale is first factored out of the existing transform before the new scale is applied. Sincerely, Daniel Selman Author - "Java 3D

Anyone seen this?  I've got a couple testers, with various hardware cofigurations that are seeing errors such as the one below.    

Re: [JAVA3D] Change j3d primitive size on fly - possible?

If you want to deform the shape along the axis, you need access to the coordinates. Add the shape to a Transformgroup and center it (by translating), so that the center of the shape is at the center of the axis system. Then do something like   for example scaling on the x axis:   get shape's

Thanks! Cristian, It looks like I can not scale the cone one direction in dependent from the other direction. the setScale is limited to uniform scale matrix in the specs. At 05:23 PM 3/29/2002 +0200, you wrote: >Add your cone to a TransformGroup, set the capabilities of the TransformGroup > >t

[JAVA3D] How can unindexing of indexed geometry be avoided?

Under which cirumstances can it be avoided that Java3D unindexes indexed geometry? If I use USE_COORD_INDEX_ONLY is it then certain that index buffers are used?   Allan

Re: [JAVA3D] Change j3d primitive size on fly - possible?

Add your cone to a TransformGroup, set the capabilities of the TransformGroup   tg.setCabability(TransformGroup.ALLOW_TRANSFORM_WRITE);   And then, when the branchgroup becomes live, you can use something like:   Transform3D t=new Transform3D(); tg.getTransform(t); t.setScale(float...); tg

" IndexedQuadArray(8, GeometryInfo.COORDINATES);"use GeometryArray.COORDINATE "setCoordinatesIndices " use setCoordinateIndices (argh crazy methods with Coordinate or Coordinates !!!)

David, I just got back from JavaOne, and Scott McNealy (Sun CEO) mentioned this 2 hour port in his keynote on Tuesday! I also got a chance to see Magicosm running at the Java 3D booth. Very nice. There was lots of interest in games for Java including J2ME/CLDC games and I saw a nice demo of GL4J

Hi,   Here's your corrected file. That error was because you named your class PointArray, which is already defined in java3d (javax.media.j3d.PointArray). I also needed to correct other errors (Tip: Remember that Java is a case sensitive language). I sugest you look into some Java2 examples a

[JAVA3D] Change j3d primitive size on fly - possible?

Hi, dear all: Is there any way to change the size of a Cone object in a live scene without using detaching/retaching BranchGroup? I mean like using Geometry By Reference, you can change vertex corrdinates on fly without adding the object under a BranchGroup, here I want to change the height and

"Don't forget J3D un-indexes indexed geometry structures before passingthem to the card" So is it better and faster to use directly non indexed geometry arrays ? The cost of memory in non indexed geometry is less than using indexed geometry ? ___

Re: [JAVA3D] PointArray example

Well, there are some errors in your code : - you sould not call your class PointArray, thats why you have a compilation error... Call it PointArrayTest instead - no return at createScenegraph method - extends your class from Applet to give a sense at the init method - ...   ___
