projecting on a ball

i was asked to project on one side of 2m ball, hooked up on stage. how would you do output setup? i suppose that just circle mask won't be enough, right?

Circle mask would be right if you have a falt circal as well...

a ball is 3D so you have to "disort" the image as well becouse some areas are further away then the center....

i would suggest you take a square slice and then use the "make a circle" function should be half the way.

You can test this as well, but it should be the wrong way ;) This is for the inside of the ball and i guess you do the outside...

Looks like something usefull,
BUT to keep it straight... either you map the globe in advanced output (square slice / make circel) OR do it with your content with an effect and then just output a plain slice (circle mask if needed) and dont disort it their...

both togther will be a mess and not usefull....


SO i guess you just need to sit down and do some testing ;) take a projektor and a ball and go for it... size dosnt matter ;)

If you have the time you also can do both... but with seperate ways... like 1 group is mapped via advaned output (slice 1)

and another group is mapped via effect slice 2
next group next effect and slice 3

multiple effects also shouldnt run at the same time..


The moon from juicebar also looks kind of good for having nice stuff happening on the ball, like having a logo and do some nice intros...

Globe effect did the job
