Mapping to spheres

[Wudang]

I want to project a number of videos onto to multiple hanging spheres.

Is my understanding correct that once the first sphere has been mapped it will act as a template for different size spheres or will I need to map each sphere size separately?

if your projectors are all the same distance and at the same angle, no, otherwise yes.

hey deepV. the 3d sphere is a 3d model, in that video, like a 3d object you rendered? hugs bern

[deepvisual]

no, they are real objects
one is a lampshade, the other is a 20m projection dome

sorry deep, my english is rather bad. let me explain. there is sphere in the video projection with lines. is it simply a 3d sphere rendered or not?

[deepvisual]

oh that is done directly in Modul8 with the transformation function.

but yes, basically it is a flat plane mapped to a sphere then projected back

ahhh thank you very much.

I making some animations now with a 3D sphere like that to be projected on a sphere like that.

but my problem is that you are doing a 180º projection and the guys are asking for a 270º projection using 4 projectors.
do you have any advice for me on this?

the new version of blendy has curved blends and use a datapath X4
