AE 6.5 ccSphere
Hello,
When i use cc sphere on an image, the back side (outside) of the sphere takes the image and ends abruptly at the end (not a seamless wrap around). What i would like to have happen, is a seamless sphere. I tend to think that the size of the image plays a part but i’m not sure how to do the math. Any help would be great.

Are you using a seamless texture just like when you map textures on spheres in 3D apps?

Hi Chris,
I am using a flat map of the earth.. While there is pleanty of water that fits seamlessly together the north and south pole do not fit together.. This is just a test, to see what cc sphere can do. So, no big deal if it won’t work. On a seperate note, I can not find the text animation preset examples. Do i need to download these examples?

CC Sphere needs an image that’s twice as wide as it is tall to work properly. Make sure the image is 2:1 (like 1600×800 – that’s just an example).
I’ve used plenty of the maps found here and they worked:

I just used those maps to animate navigation on earth. They wrap perfect. The only issue you’ll find with CCsphere is that if you put any longitude or latitude lines on it they are fat in the middle and skinny at the polar top and bottom.
Any suggestions on how to pre-comp anything on that that sphere so it doesn’t proportion out (the lines getting fatter at the equator and skinnier at the polar opposites)? Will a polar coordinates type of modification work? I work with 3d, but mostly simulation (physics/dynamics/particles) not texturing — so spherical mapping is not my cup of tea.

To create a rotating earth try this.
1. Start with a seamless flat map of the earth
2. Set Distort > offset to move image left to right over time
3. Set Distort> Bulge in centre of map
4. Set round mask over bulge to hide flat edges of the moving map.Robert Alsop
