It has a few nice features, such as a pretty good acceleration structure (basically, a hierarchical tree of bounding volumes) so that rendering complex scenes goes pretty fast, CSG support (you can subtract one volume from another or take the intersection of multiple volumes) and a decent set of basic primitives.</p> <p>Some recent changes are more general types for textures (basically, you can define your own lighting model) and the ability to place arbitrary tags on objects so that when you trace a ray, you get back a list of tags that you can use to identify the thing (or things) that a ray hit. Hopefully, this will make Glome a lot more useful for general computational geometry tasks and for interactive applications. (Glome is still too slow to be a serious competitor to OpenGL, but it's at least approaching the point where rendering in realtime is almost tolerable.)</p> </blockquote> <p><i>ABOUT THE GROUP: Join programmers, researchers and enthusiasts to discuss functional programming. pdxfunc is a study/user group exploring the world of functional programming based in Portland, Oregon. The group welcomes programmers interested in all functional languages, including Haskell, OCaml, Erlang, Scala and others, as well as using functional techniques in non-functional languages. The group meets regularly and provides presentations, demos and discussions applicable to all skill levels, from newbies and experts. The meetings are usually on the second Monday of the month. </i></p> </div> <h3>Links</h3> <ul> <li><a class="url u-url" href="http://pdxfunc.org/">Website</a></li> </ul> </div>
