> A scultpter creates a sculpture and folds a thin rubber mat around it. He hold the mat into place using thumbtacks at all of the vertices. He then paints the mat to what he wants the sculpture to look like. He doesn't have enough space to store the sculpture itself so....he writes down the exact positions in space of each thumbtack. He then writes down exactly on the mat where each thumbtack is placed. He then stores the two lists, the thumbtacks, and the mat.
> Later, a son pulls out the stuff and uses the first list and the thumbtacks to shape the object. Then he places the mat around the thumbtacks and lines it up using the second list.
BRAVO! That is a perfect way to describe what's going on! Now for a little clarification: While it is wrapped on the sculture, you place little thumb tack. Then you must take that mat and flatten it out on the floor. He then said "In 3D space, this point was (-0.56,0.435,0.45), but in the mat it is (20,64). Now the upper left corner is (0.00,0.00) -- and for a 64x64 mat -- the lower right corner is (64.00,64.00). +X (which should be called U) is to the right, +Y (which should be called V) is down. Each pixel is 1.00 units, but you can say 0.50 which would be half-way through the pixel.
