Pascal's Triangle 3D is a Java3d project which prints pascal's triangle using both a recursive and iterative algorithm.
A friend needed a software to print pascal's triangle using both a recursive and iterative algorithm. So I helped him with the code.
But then we got the idea to create a program to visualize the triangle in 3D. Well, hours of perusing Java3D documentation ensued (neither of us having ever before done anything in 3D).
The result, a hacked up version of several java3d examples that let's you rotate the triangle with your mouse and zoom in and out with keyboard.
