The implementation is to use Breukman scanner to scan the right foot of the author and apply RapidForm XOR2 to construct the surface model. Followed by the built-in function of the XOR2 software, we can map NURBS surfaces of the model and transfer it in IGES format to the Rhino 4.0 and read out the construction parameters for each NURBS surface. After extracting the parameters, we can reconstruct the foot surface and manipulate the parameters to change the foot surface. The problem in making NURBS surfaces is to choose the right color to mimic the true human foot. The first approach is using the mono color. The second approach is to take a picture of true human foot and extract part of it and use image processing to create a camouflage colors which mimics the true human foot. We compare the two approaches and discuss the implication of the control points, knot vectors and weights to the NURBS surface construction.
