System and method for controlling a three dimensional morphable model

A system for generating a geometric design, comprising:

• a pattern and relationship extraction module for generating a three dimensional statistical model of a geometric design from exemplars;
• a constraint selection and calculation module for extracting from the three dimensional statistical model a two dimensional section;
• and
• a constraint module for performing at least one constraint function on the two dimensional section of the three dimensional statistical model and similarly constraining the three dimensional model.

A method for generating a geometric design, comprising:

• generating a three dimensional statistical model of a geometric design having a set of points comprising a number of points;
• extracting from the three dimensional statistical model a two dimensional section;
• and
• constraining the two dimensional section of the three dimensional statistical model to generate a new three dimensional model.
