Hi,

I am looking to write some spatially aware code and cannot seem to see any libraries handling this.

In Java in the past I have created and Area with my shape info and then used Area.contains or Area.intersect etc to test overlaps, collisions etc.

Is there any library out there that exists to perform the computations, even if part of a graphics pacakage? A basic drawing utility might be the source for code.

Thanks in advance.

Vectors as a datatype do not exist in Erlang, even if it is a subject often discussed on the mailing list. I have however seen lots of applications integrating with graphics systems such as OpenGL and others, where the spacial aspects are all managed on the Erlang side. Another application you might find interesting is wings3d, http://www.wings3d.com/ a 3d modeler inspired by nendo. Its code is freely available as open source. You might find a bit of inspiration there.

Regards,
Francesco
