ELECTRONIC DEVICE FOR PROCESSING IMAGE-DATA, FOR SIMULATING THE BEHAVIOUR OF A DEFORMABLE OBJECT

摘要

The invention concerns an electronic device comprising a user interface with force feedback (4) corresponding to a tool reactions, a "collision" module (18) for estimating a point of intersection between a straight line embodying a displacement derived from the action of the tool and the surface mesh generation of a given object, and an internal forces module (16) which elaborates an internal forces field of between nodes of at least a part at least of the object volume mesh generation from the displacement applied on the nodes pertaining to the surface mesh generation containing the point of intersection, limit conditions, and node tensors and link tensors derived respectively for each node and each link of said part at least, matrices of rigidity, and a reaction module (20) for determining the reaction force of the object corresponding to its deformation estimated on the basis of the internal forces, such that the force generated by the user interface (4) is balanced by said reaction force.
