How to do bump mapping and/or multitexturing on a sphere?? Please help me Sorry for my english, im french

Multitexturing : look for ARB_multitexture of simply read the OpenGL specifications.

Bump-mapping : there are many ways of performing bump-mapping. From emboss to environmental bump-mapping, every effect is more or less beautiful and eats more or less CPU/GPU time. If you''re targeting decent graphics cards, say Voodoo3/TNT2 at the very least, then you could go to DOT3 Bump-mapping.
If you''re targeting top-of-the-line cards, say GeForce2 at the very least, you could try register combiners (NV) and/or fragment shaders (ATI).

You''re french ? blah I hate frenchies. Ils ont une facheuse tendance à massacrer la langue de Chèques''pire.

Sorry if you dont like frenchies!! Thanks for your help! I have a TNT2, and what are the best bump mapping?? Where can i found a tut to do bump mapping and/or multitexturing on a sphere??

You should start with NeHe tutorials. Lesson 22 treats Bump-Mapping, Multi-Texturing & Extensions even though the bump-mapping presented here is pretty depreceated.
