I'm using Processing ( http://processing.org/ ) to quickly visualize some algorithms etc...

The problem is that it is java based, which means no operator overloading so writing long equations with 2d/3d vectors using "a.add(b.sub(c.mul(d)),a),..." is getting kinda annoying.

Are there any C/C++ (or in any language with more natural math syntax) based tools like Processing?
