New tools for animation and design : a haptic-based system for stop motion camera animation and curve design by algebraic-trigonometric Pythagorean Hodograph curves

Abstract : In the first part, we present a new system that allows to create realistic cameramovements for a stop motion animation. The system improves traditional 3D software animation programs (for example Maya and 3D Studio Max) for creatingstop motion camera movements by using an haptic interface. After describing thewhole system, we explain in detail the mathematical processing to obtain differentcamera movements by using an haptic interface for motion capture. The recordedhaptic positions, once elaborated, are exported, frame by frame, to the motioncontrol software, which allows to calibrate the motion control robot, to control thecamera settings and, finally, to execute the sequences. A class of students of the"Art plastiques et Création numérique" Master of the University of Valenciennesevaluated the system. In the second part, we define a new class of Pythagorean Hodograph curves built upon a five dimensional mixed algebraic trigonometric space, and show their fundamental properties and important advantages over their well known polynomial counterpart. A complex representation for these curves is introduced and constructive approaches are provided to solve the first order Hermite interpolation problem.
