i need make simple rotating sphere planet from flat image

 

example what i need, but very light and simple without three.js:

I'm afraid this isn't so simple with a 2D library, as it involves spherical transforms. There will be examples of spherical mapping in canvas which can be applied to Phaser's BitmapData objects, so I'd Google for those.

its possible converting each point from 2D picture to 3D coordinate, but in picture 1000x1000 pixel need check 1.000.000 points

maybe phaser can use ready texture map from json file?

Phaser has no in-built 3D support; this is something that would have to be done via webGL or canvas externally - and as Phaser uses pixi which falls back to canvas on non-webGL devices, you'd need to ensure your routine also worked on both.
