Questions were asked recently about looking outward from the origin (or other location) and rotating the view of the surrounding scene. As an example of this kind of viewing, see look_around.py in the contributed section of vpython.org. Bruce Sherwood |

That's a spectacular demonstration of work that needs to be done on the beta version, as it takes 5 seconds (!) to render the scene on my laptop, whereas the display and motion are completely smooth in the production version of VPython. I've added this to the contributed section of vpython.org. Thanks! I deleted the unnecessary line that made the mouse cursor visible, since that's the default and this feature is as yet missing from the beta version, should someone wish to see the extreme slowness of the rendering.

I could possibly change it to add the asteroid objects after the main loop is started until a desired frame rate is achieved. It will still run smoothly on slower computers that way. And display the object count in a corner for comparisons. > I've added this to the contributed section of vpython.org. Thanks! You're welcome, it was fun to figure out how to do it too.

Okay, I've commented the tricky geometry calculations.
