Detailed Description

Builds off of tgRigidInfo and tgBoxInfo, but creates ghost objects instead of rigid bodies. Needs to be in its own seperate structure, so these don't get accidentally compounded with rigid objects. Used by MuscleNP and tgMultiPointStringInfo

Constructor & Destructor Documentation

tgGhostInfo::tgGhostInfo

(

const tgBox::Config &
