3D marble run construction application for scientific assessment of children's cognitive development.
Enable scientists to assess cognitive abilities of mentally challenged children by having them replicate marble run structures. Compare result to reference image. Track construction time. Physics simulation to test if marble run works. Extensible: load brick types dynamically from config files. Embedded 3D XNA view into WinForms (not officially supported).
Dynamic 3D model loading from configuration. Physics engine integration. Interface for adding new brick types. Embedded XNA 3D view into WinForms application.
Delivered to customer. Customer satisfied with result. Project completed on time.
