Or providing a time axis on all geometry (I'll let you pick between absolute and relative time). Perhaps however, there is another way to archive geometry and time besides the typical 4 dimensions. What if your objects were connected with springs with a certain amount of stretchiness. I am talking about is the 4 fundamental forces. If your entire scene was stored as forces, what would that look like? Is this being handled in X3DEarth?</div><div><br></div><div>John</div></body></html>
