BSP Trees

Lion: I read your post after starting the conversion. I decided to try and finish it anyway.

What I need now is some webspace.

It's done but it's aquite a bit slower than the C version.
It also dosn't do muti-texturing yet. I'll finnish that tonight.

It's more or less a straight conversion, but I am using dynamic arrays and setlength rather than raw allocated buffers.

Would this account for the speed loss? I'm just wondering if it's a memory pageing issue, or is there some slow down when accessing elements?

dynamic arrays are quite slow (well actually the resizing is slow), a TList might speed up the process quite a bit... not sure how to use it with records though, although there is an example in the Delphi help

If you need to store the demo for a while I can upload it to my lycos webspace or you can request your own webspace at lycos they provide 50 megs for free!

I'm not resizing while in the mail loop so I don't think its that..
..
I should have sent it to work so I could run a profiler or 2 over it.

I'm going to try and find some free webspace..
Lion, where do you sign up for the free space at lycos?
