Create twin sphere in Three.js

Hello !

I'm working on krpano plugin in Three.js and i would like to create the same sphare like in krpano. Threejs sphere should be matched (be the same) as krpano sphere! Where can i find details about krpano sphere? Is it enought set the same radius, if yes, what radius set?

someone knows any details about krpano sphere?

the internal geometry scaling is arbitrary and doesn't matter.
Only the projections matrix should be the same to get a matching.

What do you expect to get?

Best regards,

I would like to add Three.js sphere and when i add the same texture as I added in krpano, the sphere should be same to get a matching (texture matching). At the moment i don't know, what size my new sphere should be. The projections matrix is the same as were on ThreeJS (3D Objects) Plugin Source.

any size will do, there will be no differences.

When viewing a sphere from the center all sizes will look the same and also result in the same screen-projected values.

Best regards,
