Gregory's Servergood progress today, implemented the entire scaffolding for rendering a basic cube. Next is the tricky part of implementing the actual math routines for fixed-points. @d6's fix16.tal is really gonna come in handy, and I'm also wondering how to approach the square root routine -- maybe Heron's algorithm?

  @neauoire @bellinitte i just implemented it for fun for fix16.tal. it's not 100% perfect but i think it's "close enough" for most things. i had to add a counter to make sure the algorithm terminated (it's not totally stable with fixed point math) @neauoire @bellinitte it should be up now. there was a delay getting it onto the web server. |
@bellinitte i saw that @neauoire had an implementation of heron's algorithm in uxntal (but for integers), so that is probably a good place to start.
if it gives you trouble, let me know. i should probably add sqrt to fix16.tal sooner or later.
