A HAPTIC PLUG-IN SYSTEM AND METHOD FOR IMPLEMENTING HAPTIC PLUG-IN FOR EXISTING INTERACTIVE 3D COMPUTER GRAPHICS APPLICATIONS

摘要

The present invention can make a user to use feedback power rendering using haptic equipment without an additional source code work to an interactive three-dimensional computer graphics application program which was previously developed. The present invention includes a technique to extract a depth map by using an internal structure of a real time three-dimensional computer graphics based on OpenGL or Direct3D which is established nowadays. Thus, depth information which is necessary to form a haptic rendering algorithm can be extracted and used in various graphics rendering environments. The present invention includes a technique to transmit the depth map between two different software modules without disconnection. The technique can form haptic rendering of 1000 Hz capable of providing the enough feel to the user without an additional consideration regarding data input and output problems in a module which the haptic rendering algorithm.
