ComputeSprungMasses(const TArray< FVector > &, const float, TArray< float > &, FString *)

Description

Setup functions Compute the distribution of the mass of a body among springs. This method assumes that spring positions are given relative to the center of mass of the body, and that gravity occurs in the local -Z direction.

Returns true if it was able to find a valid mass configuration. If only one or two springs are included, then a valid configuration may not result in a stable suspension system - a bicycle or pogostick, for example, which is not perfectly centered may have a valid sprung mass configuration without being stable.

ComputeSprungMasses(const TArray< FVector > &, const FVector &, const float, TArray< float > &, FString *)

Description

Same as above, but allows the caller to specify spring locations in a local space which is not necessarily originated at the center of mass.
