3D Sphere

Post by still » Mon Jan 30, 2006 4:16 am

Hi diddly ho

I am looking to create an interactive display in Flash MX 2004. I have seen 3D spheres before that are made up of loads of thumbnail pictures.

The idea is that the user can mouse over any of these images and they will either expand or upon clicking them they link you to another page.

Has anyone any ideas how i would go about setting up the 3D sphere and allow the user to scroll through it.

Think of it as your inside a football looking out and when you turn your head you see other images (ie little squares of the).

Any help neighboureeeenoooo's

There are several ways to do a 3d sphere effect but it can be CPU intensive depending on the size of the sphere and how the rotation is rendered.

The simplest way would probably be to create an image for each frame of the rotation cycle but that would mean a large swf file and a lot of work creating all those images.

Another way is using layered masks. Each mask is a circle shape and slightly smaller than the one under it. This can be done entirely in ActionScript and in a single frame but it will eat up the CPU if the sphere is too large or there are too many layers. Let me know if you want an example.

Also, if you had Flash 8 you could use the displacement map filter to create a rotating sphere.
