[ODE] Status of TerrainAndCone

[Benoit Chaperot]

I use this terrain collision class for my motocross game and for me it
works fine.
www.jstarlab.com
However I have noticed that I use high ERP (0.9), and if I do collision
with tri-meshes with high ERP, the collision responses seem very strong.

First I thought it was a problem with the depths returned by the collide
function, but I am pretty sure the depths are right because they are
calculated using other ODE classes point depth functions.

I think the main problem is that the terrain collision class does not
create as many contact points as for example the tri-mesh class.

I think it is more a problem of merging contacts or creating the right
number of contact points.

Any recommendation and help for improving the terrain class is welcome.

How poor? I'm doing an arcadey racing game, so I don't need it to be
extremely precise, just enough to *look* more or less right. As long as
it doesn't explode and behaves more or less realistic, I could use it.
