Bugs / version .85 bug

When the scale() (it might also be getScale(), not sure which) method of Object3D is called, it prints the scaling value to the console.

I assume you accidentally left some denug code in, right?

It's really annoying.  It's keeping me from seeing my own debug printouts... (my program scales all objects in universe about 30 times a second)

Feedback / Still Another Suggestion...

I hope I'm not annoying you, but I have another idea, one I've actually been meaning to suggest since I looked closely at java.awt.color a couple of months ago.  I've just been forgeting to suggest...

Anyway, I was looking at java.awt.color and I noticed that all color objects have an alpha value associated with them that determines transparency.

I was wondering if setAdditionalColor() supports the alpha value.  If it doesn't use it, why not?  It seems a simple way to set both the color and the transparency of an object in one swoop...

I think it would be cool if it worked like that...

I could use a setSize() method on Object3D.

One that changes it to a particular size instead of having to mess around with changing the object back to it's original size first.

I need a way to iterate over all the Object3D's that are attached to a particular World instance.  I saw no way to do that in jPCT's API.
   I guess for now I'll just have to keep an external LinkedList to do this, but I just thought I'd make the request.  Preferably I would like to have an iterator object to work with.
   In addition, a method to remove all objects from a world would be extremely helpful to me.
On a side note (for curiousity's sake) I was wondering how does jPCT's World class store it's references to Object3D's?

Projects / Undergrad Research: Creating Life in a Digital Medium

I'm doing an undergraduate research project using jPCT.

I'm working on creating a semi-realistic physical environment involoving real-world physics (Gravity, collisions, etc.) in space using only spherical objects (for simplicity's sake).

Once I have the minimum level of physics done (should be in a few weeks) I'll be moving on to inserting objects into the universe that mimic plants (photosynthesis).

I'll also be working on a background process that will mimic the effects of radiation exposure, altering the genetics of the life forms as they live their short lives (about five minutes).  This should allow evolution.

In this project, jPCT is being used just for the rendering of objects and life forms, so you can see them interacting with eachother.  Anything and everything else will be done as much as possible from the project's code, in order to divorce it from the renderer as much as possible.  That way, it could fairly easily be ported to another renderer (like Java3D for example, if you want hardware acceleration), or be left to run with little to no user interface, and a java applet used to view what's going on from another machine.
