Which parts are you having trouble with?
Do you have to generate sphere maps, do you have to use existing sphere-maps to implement environment-mapping, or both?
Which graphics API are you using? Are you using shaders?
What have you tried so far? What sources of information have you used so far?
Is there a reason you want to use sphere-mapping instead of other techniques, such as cube-mapping?
