Warping, a Physical Analogy

• Imagine an image printed on a sheet of rubber

• Could change image by moving thin rigid rods glued to the rubber sheet

• We would place these rods along contours of important features, such as eyes, nose, mouth, face outlines, etc.

• Imagine also that the rods can change length, as well as position.

Warp speed pop-question

• What now-familiar method could we use to calculate the intermediate positions and sizes of the rods?
