基于力反馈技术的三维模型表面绘制研究
Research on 3D model surface rendering based on force feedback technology
摘要
Abstract
This paper proposed a novel method of 3D model surface rending by applying force feedback technology to virtual painting processes.Firstly,it analyzed the relationship between force and the brush deformation,and applied the spring-mass model to construct the 3D brush model.Then,it found out the collision related points by the most enclosing ball of the deformed brush,and calculated the average normal vector of the collision point to determine the projection plane.According to the deformation of the 3D brush,it calculated the footprint of the brush on the plane and obtained the 3D brush footprint by projecting the 2D brush footprint onto the 3D object surface in real time.At the same time,it obtained the specific complete calligraphy effect 3D brush stroke by superimposing 3D brush footprints along the painting direction and controlling the stress of the brush.Finally,this paper briefly discussed the simulation structure and established the virtual 3D painting system based on Phantiom Desktop device.The proposed method implementes the 3D painting in real time with a Phantom Desktop haptic device,which can effectively enhance reality to users.关键词
