Corrective blendshapes/deltas as the form of an linear combination unknown.

I’ve just started watching the Gilbert Strang MIT Courseware on iTunes, and highly recommend it – after watching it a light bulb went off in my head. Daniel Pook Kolb’s Blendshape system is very very impressive – but I did’nt and still dont understand it fully.

Thinking out loud here I thought that it might be essentially a form of finding out the ‘unknown’ in a linear combination of an nth dimensional space as the corrective of the combining shapes. For example the unknown of : 

x[2,3] +  y [4,5]  = [6,7] would be [-1, 2] ( its hard to show as i’m not using LaTex atm)

Before any corrective is used the  ‘unknown’ is [0,0], this would be synomanous to  adding two blendshapes together without any corrective.
