    I didn't get how to go from 3D (homogenous) transformation matrix into 4D rotation matrix. Can someone please send any references?

      In one of the previous lectures they mentioned that they may just scale-down translation component. I guess such that it always within 0...1 range

      [R,(d*t);0,0,0,1]~[R,(d/2)*t;-(d/2)*(t^T)*(R^T),1]
      R=Rotation
      t= Translation
      ^T= transpose
      d= characteristic length
