Talk:Stereographic Projection

Can you make the animation bigger? I can't see what's going on :(

Sorry about the delay, but I finally fixed that bug, thanks for the heads up.

I really like what you've done with the applet. One bug I've noticed is that if you click and drag the mouse far enough off the applet, the applet itself blacks out. It would be great if you could fix this problem, but otherwise, it's not a huge deal. It's a great addition to the page!

Hey I've modified the applet to accept user input, but instead of using sliders you can simply click and drag your mouse to rotate the sphere: Stereographic Projection

Actually the applet does work for me, I just needed to update my java platform. That's a very nice animation, thanks! Based on the animation you've made, maybe some sliders could control the orientation of the sphere- a slider or two could rotate the sphere in different ways, such as one to rotate in the $\phi$ -direction and one to rotate in the $\theta$ -direction.

To be clear, $\theta$ direction would be rotation away from the x-axis within the x-y direction and $\phi$ direction would be rotation 'away from' the z-axis: -Brendan 6/26

This looks like a pretty interesting illustration of the concept YouTube Stereographic Projection.

I've created a basic stereographic projection applet, check it out and let me know what else should be in there (i'll get to the sliders soon): Stereographic Projection

-Steve (from Drexel) 6/24

Hey Drexel folks,

An applet for this page would be really cool. I was thinking of an applet with some sliders that would allow the user to move a point on the sphere around, and a line would actively show the user where the point they control is projected to on a plane.

Can you use the Riemann Sphere page as something related?

The way you added that was exactly what I had in mind, and I think it works well.
