The Persistence of Vision Raytracer is a high-quality, totally free tool for creating three-dimensional graphics.
The goban image on the front page of SL is rendered with POV-Ray.

wms: The KGS "splash screen" and web graphics were made with POV ray. If you tell POV ray to use an infinite-zoom-infinitely-far-away camera (can't remember what POVray calls this, it's the camera setting where the rendering rays are all parallel to each other instead of emanating from a single point near the image), then you can get nice images that look "flat" on a web page instead of having perspective. POVray is very handy for this sort of thing, but of course has its limits; the actual boards in KGS are generated programmatically to make sure different sizes can be generated without having pixelization due to scaling errors.
gimpf: POVRay has its limits, but what has this to do with procedural textures? (btw, I think you meant the orthogonal camera)
zpmorgan: Here is my attempt at go stones suitable for a computer program. It is based on code from Nicolas Rougier.
Some links for POV-Ray Go (sorted from the best on top to not so best on bottom):
- totally wonderful pictures by Nicolas Rougier, the best what I have seen
- the image from SL frontpage
- here you can download macro for making simple goban
- http://www.3dgo.org/ Eric Piotrovski
- the sad thing is that the stones look very flat

- Stone's renderings.
axd: I have the impression that the jpeg compression does not work well together with the fine wood grain; the vertical goban lines seem to interact with the wood lines. Maybe a higher resolution, or a different angle (or file format) might solve that?
Tenchi: I did my own POV-Ray scene, along with a python script for generating a POV-Ray scene for any .sgf game at any position. I post it here since I don't know where to insert it (the links are sorted by best to not so best): ; http://tenchi.me/site/index.php?p=pov_goban (dead link)
