THE HAPTIC DISPLAY OF COMPLEX GRAPHICAL ENVIRONMENTS
专利汇可以提供THE HAPTIC DISPLAY OF COMPLEX GRAPHICAL ENVIRONMENTS专利检索，专利查询，专利分析的服务。并且The present invention relates to a haptic rendering system (40) for simulating virtual solid objects in complex virtual environments. The system (40) comprises a stereographic display unit (42) capable of displaying a visual image in 3 dimensions, a haptic device (44) for interaction between a user of said system (40) and said virtual solid objects, and a haptic controller (46) for controlling force (and/or torque) feedback to said haptic device (44). The system (40) also comprises a means (48) for using a virtual proxy, which is a representative object that substitutes for said haptic device (44) in said virtual environment. The system (40) also comprises a means (50) for determining a point/points on a surface/surfaces on each said virtual solid object, which point/points represent a distance minimum (mi) with respect to said virtual proxy. The system (40) also comprises a means (52) for calculating, for each said distance minimum (mi), a surface normal (ni) as a unit-length vector, a means (54) for producing exclusion planes by the use of the resulting set of (mi) and (ni), which planes are used to exclude said virtual proxy from entering said virtual solid object, and a means (56) for determining expelling forces to push said haptic device (44) towards said virtual proxy.，下面是THE HAPTIC DISPLAY OF COMPLEX GRAPHICAL ENVIRONMENTS专利的具体信息内容。
