Free-hand stroke based NURBS surface for sketching and deforming 3D contents

Abstract

This research is to make a series of NURBS surfaces for the virtual 3D conceptual design and the styling process by applying arbitrary free-hand strokes. The surface can be modified in real-time calligraphic stroke based free form deformation. The suggested algorithm is used to create 3D NURBS surfaces for styling object using free-hand strokes with the posture information of the input wand. The algorithm presented in this paper can help product designers in the conceptual engineering stage, even if he or she has no idea about the shape of a target product.
