Grasping remains a complex topic for simulation. Embodiments provide a method to automatically determine grasping cues for tools. An example embodiment scans a CAD model representing a real-world tool to generate a series of sections from the CAD model. In turn, properties of each section are extracted and one or more regions of the CAD model are identified based upon the extracted properties and a tool family to which the tool represented by the CAD model belongs. To continue, a respective classification for each of the one or more identified regions is identified and grasping cues for the CAD model are generated based upon the determined respective classification for each of the one or more regions.

Extracting grasping cues from tool geometry for digital human models

A method is disclosed allowing digital 3D models to be indexed, searched, and compared, and to display the results in a 3D space. The method comprises four complementary parts: displaying, comparing/searching, face reconciliation, and ranking results. Each of these parts can fit in one another or be used independently. The implementation of a process for searching/comparing 3D models based on descriptors at least partly related to faces requires a face reconciliation process (pairing of faces between 3D models).
