Going Through the Steps

• Adjust the scale so the back clip plane lies at z = -1

• Our current transformation (applied to everything) looks like this:
  
  

• Let's combine the three rotations into one matrix we'll call R , so it's
  
  

• We need to shrink the back plane, now at some point until it is at . We can do this by scaling in z:
