Abstract
We have investigated several areas in 4D visualization, including 4-dimensional space rendering, various user interface elements to manipulate the 4D objects. In this paper, we describe methods for visualizing 4D polytopes that are texture-mapped, and present an environment that achieves integration between 4D trans- formations, 4D motions and interactive visualization with an intuitive interfaces. In the environment, all the motions in 3D and 4D can be performed under the control of key-frame and mouse. We expect the system runs smoothly and the observation and interaction with 4D polytopes are effective for intuitive understanding of 4D polytopes.
