Shoe design through 2.5-dimensional shoe models

A system comprising:

• a 2D shoe shell pattern engine configured to:
• access a 2-dimensional (2D) shoe shell pattern, the 2D shoe shell pattern generated for shoe design;
• and
• a 2.5D shoe model engine configured to:
• generate a 2.5-dimensional (2.5D) shoe model by placing shoe design elements provided by a user onto the 2D shoe shell pattern of the shoe, including by adding 2.5D layering data for each shoe design element placed on the 2D shoe shell pattern to form the 2.5D shoe model;
• and
• wrap the 2.5D shoe model into a 3-dimensional (3D) shoe model for construction of a physical shoe from the 3D shoe model.

A non-transitory machine-readable medium comprising instructions that, when executed by a processor, cause a system to:

• access a 2-dimensional (2D) shoe shell pattern, the 2D shoe shell pattern generated for shoe design;
• generate a 2.5-dimensional (2.5D) shoe model by placing shoe design elements provided by a user onto the 2D shoe shell pattern of the shoe, including by adding 2.5D layering data for each shoe design element placed on the 2D shoe shell pattern to form the 2.5D shoe model;
• and
• wrap the 2.5D shoe model into a 3-dimensional (3D) shoe model for construction of a physical shoe from the 3D shoe model.
