Sergey Sharybin added sphere and tube mapping options to the image node yesterday:
[12ccac6] Cycles: Support sphere mapping for the image texture
[dda3554] Cycles: Support tube projection for images
What is it?
Just the same mapping types we’ve had in BI for years ;)
Sphere mapping allows us, for example, to painlessly map a texture of the Earth onto a sphere without needing to do any UV mapping.
How do I use it?
Simply change the projection method on you image node from Flat to Sphere or Tube, and probably you’ll want to use generated coordinates.
Sorry I’m new into blender, how to update my version of blender, do i use the links you provided
This will be in 2.74 for sure, but until that is released you can get a build from the buildbot: https://builder.blender.org/download/ or from graphicall.org
