[JAVA3D] Accurate Collisions (II)

Hi, Thanks Kelvin for your suggestions, but again it fails. It might be due to the way the vertical boxes are defined, I don't know. As you can see in the image enclosed in this message the result is absolutely useless. I send you along with the image the used java code for you to see it. The o

[JAVA3D] Can a line be coloured in a lit world?

Hi, I'm trying (and trying...) to give colour to a line (LineArray, LineStripArray...) in a lit world (yes, with litgths) but they appear black. I use material color and/or per vertex geometry color but nothing happens. Can the lines be in color in Java 3D ? (Coloring attributes doesn´t work) Th

[JAVA3D] How can I make Screen Zoom

Hi, I want to make Zoom but without modify the objects int the virtual world, neither the size of the screen. I mean, I just want to see the same objects (some of them will dissappear, I know) but bigger, just like a normal zoom. But I don't want to change the size of the objects in the geometry.

Re: [JAVA3D] Arrow Geometry Needed

Hi Javier, Here I am attaching a sample file that draws arrows. the arrow class has a function that will return a "TransformGroup" node having the arrow below it. This is a 3D arrow and made up of two cones and a cylinder. The input parameters are arrow diameter, start point and end point. (Note

[JAVA3D] Storage of polygon normals

Being new to Java 3D I may be missing something, but I don't see any way to specify a SINGLE normal to be used in lighting calculations for the vertices in a triangle. My problem is that I would like to specify the 8 vertices and the 6 normals for a box. Using GeometryArray classes, it looks lik

Hi, I have the following problem. I have written an applet that incorporates collision detection. The applet has been run on 2 machines: one with NT operating system, and one with Win98 running on a Compaq Presario P-III. On the NT box the collision detection works correctly. On the Win98 the

Re: [JAVA3D] rotationInterpolator

I'm curious to how to go about this too. Actually, I just need to define some animations in advance that will move parts of a model to appropriate positions. For instance, an animation of a figure taking two steps to be looped as the animation for walking. Is it possible to some how "group" dif

My understanding is that you can group parts of the sceen based on their movement. Each group has a transformation that applies to all the Shapes below it. > -- > From: Drakein of EiT[SMTP:[EMAIL PROTECTED]] > Reply To: Discussion list for Java 3D API > Sent: Tuesday,

[JAVA3D] Long life to j3d

Hi fellow j3d addicts, I will leave my current company at the end of this week and will so probably end my involvement in j3d for a while. This has been a great and exciting (yet sometimes frustrating ;-) time to follow the birth and progress of the API through this group. I want to thank everyone

As an example, to manipulate an arm with hand and fingers, you might set up your tree like this: armTG |__armShape |__handTG |__handShape |__thumbTG | |__thumbShape |__fingerTG1 | |__fingerShape1 |__fingerTG2 | |__fingerShape2 |__fingerTG3 | |__fingerShape3 |__fi
