Re: [JAVA3D]

Hi Andy,   You can't construct a point3f with a single value, you need to specify three, (one for each axis), to make up the co-ordinate.    If you want to cast the int into a float you can turn it into an Integer and then use Integer.floatValue(); but you'll still need the two other value

[JAVA3D] Generating objects with the union / intersection of another objects.

Re: [JAVA3D] Behavior Problems!

I'm not familiar with the scaling behavior but the way that the other behaviors needed corrected is basically a coordinate transformation. You may need to modify the scaling behavior so that it remembers the objects position, then translates it to the origin, scales it and then translates it back

[JAVA3D] Java3D in an applet

Hey - I was curious if anyone's noticed the problem of using Java3D in an applet. What I notice is that if the browser's window is moved or resized, the 3D object/scene remains in it's original position. Thus if I have a scene with a single rotating sphere and move the window to the right half o

Paul, We have definitely experienced the same problem. Our assumption was that we weren't passing an event down to the canvas somehow, but if you are seeing the same behavior it could be a fundamental difference between applications and applets. Any ideas? --Mark At 09:05 AM 1/18/2001 -0500,

Re: [JAVA3D] Generating objects with the union / intersection of another objects.

I would say the union is possible. As for the intersection, I can't see it happening. Union simply means all of object A and all of object B unite to make an object C. I have never attempted it, but I think this may work: Once you have detected that the two objects are coliding, and the user re

Re: [JAVA3D] Behavior Problems!

The scaling of an object is done as written below by Eric. If you see that the scaling is also influencing the position then you have: 1. The object is not possitioned at origo (center of the object) 2. The coordinates of the object are off-origo. The first is not that difficult. You have to rem

Re: [JAVA3D] Generating objects with the union / intersection of another objects.

Well thats not really a solid object boolean union, which I assumed is what they were looking for. To do the merge I would think you would need to construct a new mesh, which Java3d does not support doing inherently. Maybe I am splitting hairs here. But I don't want anyone to be misled and thin

Re: [JAVA3D] Generating objects with the union / intersection of another objects.

I know it's not quite creating the new mesh. However, in effect it is the same thing, since, to my knowledge, it will not even attempt to render the parts that are hidden. So the extra vertices will be (almost) as good as non-existant. You are right, though. It only "looks" like a union. But

Re: [JAVA3D] Checking for movement

To get the distance to the view: 1. Get the transform which is translating the object and get the translation vector. This only works if the shape itself is built around the origin and then translated, as most are. 2. get the view transform, gets its translation vector. 3. calculate the distance

Use detach() on a BranchGroup() and make sure the capabilities are set on the BranchGroup to ALLOW_DETACH. You cannot remove a child on a active scenegraph, you have to detach a branch group. > -- > From: Elio Vega[SMTP:[EMAIL PROTECTED]] > Reply To: Discussion list for Java

If the shape wasn't build in the origin, is there a way to find these coordinates? (i.e. find the coordinates where it was constructed so that the translation vector can get added to that?) Thanks in advance, Paris --- "Yazel, David J." <[EMAIL PROTECTED]> wrote: > To get the distance to the vie
