Trumps's all hot air anyway
as i'm playing around with my renderer some more, i really wish i could have this geometry to render!
how difficult was hart's method to implement?
Hart's method (as I implimented it) was fairly easy to impliment, the only thing is that his suggested method for getting the normals doesn't work terribly well especially for flat-sided objects like these Sierpinski buildings or Menger objects. It works a bit better for more "roundy" objects but I still prefer results from using the "z-buffer" method. As to the ray-trace the code I'm using is essentially what I sent you earlier except that I had to add re-calculation of dx*dx+dy*dy+dz*dz where dx,dy,dz is the ray's direction vector. Just look at the init: section of mmf4.ufm from the Ultrafractal formula database if you want to check out the code as it stands - [link]
The one thing I'd like to improve is the automatic calculation of the bounding sphere's centre and radius - here I'm leaning towards doing a partial chaos-game or deterministic mini-render to get the centre and extent.
