摘要:In this paper we present an analytical study to select 3D objects based on their shape pointing device in a virtual environment(VE). We adapt a 2D picking metaphor to 3D selection in Virtual environment’s by changing the projection and view matrices according tothe position and orientation of a pointing device and rendering a conic selection volume to an off-screen pixel buffer. This method works fortriangulated as well as volume rendered objects, no explicit geometric representation is required. In this paper I focused the advantages ofconic volume technique over bounding box technique in picking object in Non immersive Virtual world. The usefulness and effectiveness ofthe proposed evaluation measures are shown by reporting the performance evaluation of two algorithms. We then compare the application ofboth techniques with related work to demonstrate that they are more suitable
