3D vector libs for OCaml?

3D vector libs for OCaml?

[Richard Jones]

I'm looking for a 3D vector library for OCaml.  In particular I'm
interested in:

* points, rays, vectors, surfaces
* intersection of sphere and ray, surface and ray, etc.

Simple enough to write myself, but I was hoping that one would already
exist.  I checked the Humps, and the nearest I could find are GeOCaml,
which seems to be 2D only, and SOCaml which is the OCaml interface to
Open Inventor, which is not quite what I'm looking for.

Thanks in advance,

Rich.

Hello,

I am not sure if this exactly fits your needs, but PsiLAB
(http://psilab.sourceforge.net/) is available for the types of
mathematical operations you are talking about.  At the very least, it
provides extensive matrix/linear algebra operations, which you could
use to write your own (assuming another is unavailable).

Regards,

Sachin.

Sounds like ray-tracing territory. IIRC there was an ocaml ray-tracer entry to 
one of the old ICFP contests. I suspect the source is available and should 
fill many of those holes.

Will this be performance critical?

Cheers,
Jon.

Thanks - I found the source to the ray tracer
(http://caml.inria.fr/icfp00-contest/) which is very useful.

I'm just messing around with some 3D scene stuff ...

There's also a raytracer written in O'Caml available at
