Hi,

What I do is only test collision on tri's which the player is not allowed to 
walk on i.e. by testing the normal->y component of the surface.
Then, to determine the player's y position, I shoot a ray straight down and 
see which tri this hits and from that compute the y of where the player is 
standing.
This stops wallowing around in creases :) and also cues which sounds to play 
for the players footsteps based on the texture type under the player.

Does your algorithm also have the undesirable effect in a concave corner 
where two walls meet??
