can't calculate inetria of a shpere

if i try to calcualte the inetria of a sphere using the ogrenewt::momentofinertia
i get a linker error:
ballmaze.obj : error LNK2001: unresolved external symbol "class Ogre::Vector3 __cdecl OgreNewt::MomentOfInertia::CalcSphereHollor(float,float)" (?CalcSphereHollor@MomentOfInertia@OgreNewt@@YA?AVVector3@Ogre@@MM@Z)
bin\Debug\ballmaze.exe : fatal error LNK1120: 1 unresolved externals

I will try to investigate that.. are you sure the function name hasn't changed since you last compiled OgreNewt?

also there is now a generalized way to calculate moment of inertia with OgreNewt::ConvexCollision::calculateInertial() (I think that was the function name).

I think it's OgreNewt::ConvexCollision::calculateInertialMatrix(&inertia, &offset)

Just a quick question. Is that function only for convex hulls, or can it be used for other shapes too?

I'm under the impression that using shapes is faster than using convex hull, is that correct?

that function will work for all convex shapes (so everything but TreeCollisions).

Ah, ok thanks

Sorry to revive this old therad but I had the same problem today and found the problem. This method is named wrong in the header file. It's in OgreNewt_Tools.h and should be calles

_OgreNewtExport Ogre::Vector3 CalcSphereHollow(Ogre::Real mass, Ogre::Real radius );

instead of

_OgreNewtExport Ogre::Vector3 CalcSphereHollor(Ogre::Real mass, Ogre::Real radius );

Hope this helps

Btw, its spelled correct in the .cpp file.
