Title:
VIRTUAL DIGITAL SCULPTING METHOD BASED ON NATURAL HAND GESTURES
Document Type and Number:
WIPO Patent Application WO/2018/045670
Kind Code:
A1
Abstract:
A virtual digital sculpting method based on natural hand gestures, comprising the following steps: hand gesture position acquisition, the hand gesture position being acquired by means of leap motion; and virtual sculpture modelling. When implementing virtual sculpting tasks, there are two main models, one being a constructed model to be sculpted, and one being a virtual hand model constructed of joint coordinates acquired by means of leap motion; when the human hand moves under leap motion, controlling the virtual hand to make a slight impact on the fixed model to be sculpted, detecting whether there is an intersection point at the impact site by means of a three dimensional space triangle and triangle intersection algorithm, and the intersecting line position and, on the basis of a calculation of the impact depth, using a virtual sculpting deformation algorithm to perform real-time modification of the intersection point position coordinates, thereby achieving a sculpting deformation effect.
