cartesian coordinates system

[saufesma]

Hello there

Does anybody knows of a library in lisp to deal with cartesian coordinates system?

What operations are you looking for? How many dimensions? What does this library integrate with?

On one hand, there are simple roll-your-own solutions, such as the complex coordinate system in SICP.

On the other hand, there are complex vectorized solutions, such as for SSE or GPU acceleration.

Most graphics libraries have their own 2D or 3D vector library.

I need to check length of rod from four-link mechanism kinematic analysis, so I need 2D. And I assume I need functions to deal with angles of movement of crank and rocker arm. So to speak.
