TMCArray<TVector3> TMCLocationRec::fNormalAcceleration
 

These values aren't exactly the normal acceleration: a smoothing is done to avoid discontinuity at the junction of 2 beziers curves.

TVector3 TMCLocationRec::fPrevControlDirection [protected]
 

PrevControl and NextControl relative to Location: a normalize vector and a distance => we are so able to keep a direction even if the distance is 0

real32 TMCLocationRec::fPrevControlDistance [protected]
 

TVector3 TMCLocationRec::fPrevControlVectorUp [protected]
 

The VectorUp is normal to the path and is used to define a base attached to the path. Its determination is based on the fNextVectorUp of the previous TMCLocationRec as this: it's the projection of the previous fVectorUp on the plane normal to the tangeant. There're 2 vector per TMCLocationRec because it can have a discontinuity. fNextVectorUp is computed from fPrevVectorUp
