Foot measurement and footwear manufacture systems and methods. A three-dimensional foot frame of a foot and pressure data corresponding to a bottom of the foot are measured, and a first and a second group of characteristic points are respectively determined accordingly. A preset foot skeleton template model is adjusted according to the second group of characteristic points, and merged into the three-dimensional foot frame according to the first group of characteristic points and protrusion points of the adjusted foot skeleton template model. The protrusion points and/or joint points of the adjusted foot skeleton template model are connected to generate at least one line and at least one plane, intersecting the three-dimensional foot frame at contact points and contact planes, respectively. The foot frame size is determined according to the distance between the contact points and the girth of the contact planes.

A method of area partition in virtual environment is disclosed. It can be used to divide 3D (Three Dimensions) virtual environment into several subareas. The invention interposes neighboring subareas so that the subareas in the same plane and the subareas in adjacent planes mix with one another. Both the number of subareas adjacent to each subarea and the number of subareas an object crosses can be decreased, thus lowering the load in operations.
