[Credits to Gaheris and dhdd for this implementation]
The class is already well implemented, and tested. No possible bugs that I can think of. I will need this for my project, so I decided to upload it to the repository. It would be a nice addition to the engine.
These curves are really helpful. As an example: I will be using this for pathfinding. I'll express the chosen paths via instances of Vector3f representing the positions. Then, by calculating a Catmull-Rom curve with those positions as input, the agents of the game will move smoothly, no rigid turns ;)
Of course, this would fall under the com.jme.curve package.
Maybe it needs to be a little polished…?
here it is, the CRC and Test class Patch:
The class TestCatmullRomCurve is the same as TestBezierCurve. I think its best because new members can easily see the main difference between those two fine curves I'll check it in after 48 hours
