the download works fine now, thaks.
Cool, something like that is what I am trying to do. Any chance I could get a look at the source code for that?

I will probably just submit it to the AUM or Acknex resources so it dosent get
lost.

Basically, just use c_trace aligned with your player to get the normal of the
polygon directly beneath, then align your character to it. For convex surface,
you really need to interpolate with something like vec_lerp, especially if the
surface is low poly.

I love that demo, play it quite often mindlessly and try and make him drop in funny places looking for the 'forever drop'

I dont know if your portal one is the one I pkayed with too but it was another goody.

This is the part I have the problem with.
I keep getting gimbal lock near the equator. And I have tried dozens of way around it but no luck.
I'd like to see the code of one that works, so I can understand what Im doing stupid wrong.
(BTW, I'm running around the inside of a sphere, not the outside)

Here is one from 2006, "walking inside a sphere".
The camera stinks, and the sphere is low poly, but it uses the same idea as the prey demo.

Ooooh. Yummy! Thanks Grafton. Very generous.
I dont have time to look at it right now, maybe later today.

WARNING :: I may have questions.

Once again, many thanks...

Impressive! Be great to have it do it on a larger model sphere but then you wouldnt need wall walking, just move the world
