  Re: Reiterate: How to make a squish matrix?
 
(...) Yes, but you cannot put (1-y/L) into a transformation matrix. It is a *function* that changes for each 3D point. The purpose of a tranformation matrix is to precalculate a matrix of *numbers* that gets multiplied by all the points of the (...) (23 years ago, 25-Apr-01, to lugnet.cad, lugnet.cad.ray)
 
  Re: Reiterate: How to make a squish matrix?
 
that shouldn't be too hard either. just operate the matrix on the points alone. if your cilinder has it's axle around the Y axle. L is the length of the cilinder and if it starts at 0 0 0 you could use (1-y/L) 0 0 0 1 0 0 0 (1-y/L) this would turn (...) (23 years ago, 25-Apr-01, to lugnet.cad, lugnet.cad.ray)

  Re: Reiterate: How to make a squish matrix?
 
(...) Yes, but it's not what Sproat needs. He needs to scale X and Z as a function of Y. Something like: x' = xy Which is something transform matrices cannot do. Steve (23 years ago, 25-Apr-01, to lugnet.cad, lugnet.cad.ray)
