We have been developing fundamental software which supports to develop a conference system with virtual reality technology. OpenGL Fusion is one of technology that we have developed in the work. The techonology allows us to assemble two or more 3D graphics output in a virtual space. Therefore, what we should do is just to develop 3D graphics software, not need specializing to virtual reality. In this paper, we reports a test when a video avatar and animation software works in a virtual, space at the sametime.
