[ODE] 3 beginner questions

[Bob Ives]

Of course meant I use  ax+by+cz+d=0.  I realise now that ax+by+cz-d=0 is also a standard, so I guess Ode is using the second.

3. I´ve added bounding planes as per your suggestion.  Duh!  One curious thing though: I use the standard ax+bx+cx+d=0 equation for
my planes, but I found I had to negate d when passing the plane to ode for the collision to work correctly ( at least with
dCollideSpherePlane ).  Does Ode use ax+bx+cx-d=0 or is that a bug?
