How do I map text onto a sphere?

Questions & Answers

I’m looking for a way to map text onto a sphere (and then update it pretty frequently). It’s been a while since I’ve used Unity, so I’m not familiar with all of the latest and greatest features, but I have two ideas. I’m just not sure if either is practical.

  1. I could somehow write the text to a Texture2D and then give that to the sphere
  2. I could set up a bunch of projectors around the outside of the sphere, each projecting a single character (or possibly more), and then update as required.

Is either of these ideas workable? I did some research and haven’t found a lot of support for rendering text to a Texture2D, and the projector idea doesn’t sound very efficient. If not, what are my options?

Hi I would avoid the projector method. I have made a text displaying sphere for you below(just a rough example). However the Text is just an Image texture using a Material with a transparent shader), so you would need to find a way to convert your text(like you said above) in order to use this method.

EDIT : Take a look at this :

this does what you need, may take a bit of figuring out but the demo works very well.
