Hi

Is it possible to find out which vertices belong to a polygon? So I can then use a vertex controller to manipulate those..

thanks

Hi
As part of a term project, a friend and I been working on porting a little visualisation tool from Java3d over to jpct(pure software mode) the last ~2-3 weeks.
This was done because people kept having troubles running it under Java3d. The new version runs suprisingly smooth(given
a few things are probably implemented quite inefficient due to lack of time) even on low end computers.

The tool's named 3DCov and is used to visualize the relation between classes and objects(for OO beginners). Following a few screens of a loaded diagram:




2d/3d view. 2d is done using JGraph
Some classes/objects moved around
Popup menu
Labels(multiplicity, roles, ...)

Happy new year everyone

I started working on a collada loader(because..well..I had no other project idea ) a few weeks ago. I didn't get very far, mainly because I kinda lost interest in it and lack of time.

It currently doesen't do much more than loading basic(mesh) geometrie.

Some pictures:

Todo:

* supporting a subset of the effects librarie(correct texturing ..the one on the duck is applied after loading the model)
* light, camera and scene loading(so you get a configured world instead of object3d's)
* complex geometrie
* ...collada is huge

I don't think that I'll work on it again soon. If anyone is interested in the source ill upload it.

Hi

Having trouble with what i think is pretty basic . I most probably just dont understand how rotation works.. .

Im trying to draw some axis arrows..so I made my own arrow object3d and added it to a scene(see picture..the negativ y one is the original).
Now Id like to rotate that arrow to align it with the other axis. When i do the following:

o3ds[0] = createArrow();
       
       o3ds[1] = createArrow();
       o3ds[1].rotateZ((float)Math.toRadians(-90));
       
       o3ds[2] = createArrow();
       o3ds[2].rotateX((float)Math.toRadians(90));
       


it looks like this:


Now..is there a way to rotate these arrow so I dont have to translate them back in position(sphere is 0,0,0)? I tried setting the pivot and center of the arrow inside the sphere(which is the origin of the axis arrow too) but it doesent seem to work either.

Hi
I'm porting a visualisation tool from Java3d to jpct, and am currently working on a prototype.

So far everything works fine, and most functionality is alrdy ported, except one major thing which i couldn't solve yet.

1. I need to project dynamic generated text on a box(see picture). Is there a clever way of doing that in jpct?

2. The boxes need to "glow"(e.g. get brigther) once selected. Whats the proper way of doing that in software mode? Use a texture effect? Anyone did something like that befor?

thx

it should look like this:
