In better shape

The

(NSF) has awarded

a Phase II research grant for digital shape sampling and processing (DSSP) technology that promises to have a profound impact on product development.

Under Phase I of the NSF grant, Raindrop Geomagic used Morse Theory research to create a structured representation of a computer model by distinguishing between flat and highly curved feature surfaces.

Expanded research in Phase II will include work to automatically construct a natural structure of the resulting CAD model, identify different surface attributes and fillet types, and provide a more efficient and automated process for creating surfaces with high accuracy and smoothness.

The proposed technology will enable users to easily create accurate representations of scanned physical parts. According to a statement, this will provide an efficient closed-loop between physical parts and their digital representations at any phase of a product life cycle.

Commercial applications for this technology include design and analysis of complex shapes such as turbine blades, transmission housings, and engine blocks; creating digital inventory of legacy parts; historical preservation; mass customisation; and biometric shape reconstruction.
