Can someone copy here a Shadow routine, that makes all the objects shadows that has in my 3d surface, by a Light point ? For example: I pass as parameter the Light position and this function makes all the shadows for me. But anything that dont use Arb_multitexture_Something_like_that because my computer does not suport this function. Thank you all and c ya =)

What you are asking is not easy at all.
The simplest way to make shadows is the stencil projective shadows. They are fast, easy to understand, but have the dissadvantage that you can only project them on a flat ground.
I wrote an article on my site, check it here.
BTW, ignore the multiple source shadows part in the article, most of the times it gives crappy shadows.

Shadows arent a beginners subject really. Doing them properly will be almost impossible to do for a beginner. Its not just something you can write code for that will plug into any code situation. You have to write the code for them that will work into your engine.

hey before you waste your time on trying something complexe like shadows i d suggest you create your own camera and maybe map format so you have atleast something more complex to test your shadows with not just a cube and a plane rofl

I know it''s quick and dirty (just the way it should be ; ), but if you just want something simple to anchor your apples to the ground then just render a black circle below them.

I was forced at flunk-point to make a pacman clone for one of my uni modules, and all of my food bits looked really strange until I put drop shadows under them. If you have a kinda cartoony look to begin with it''s all you need.
