C++ and OpenGL

[rempires]

Okay, so right know i'm in high school and I'm currently in c++ programming, but because of my high grades in it and because I know other languages (php, vb.net...) my teacher thought I'd make a good student aid because i already have the logic down. cool, so next year i'll be taking a class where i sit for 7/8 of the time trying to find something to do.  I've decided i want to learn openGL. my sisters peoncey(sry, i don't know how to spell it) is a computer science major and already learned it, he demonstrated some of teh amt behind it, and i got it, i had a hard time, it was a challenge but i got it.  So i've decided upon learning this next year in my free time, i thought i'd start with a nice book, but they all assume you have previous graphical knowledge and what not.  I have programming knowledge and good algorithm skills, but I've never tried to work with graphics before, this my first time.  I decided to learn this with c++ so that it can run on multiple operating systems.  If somone could please point em int eh right direction, book, online tutorials, anything, for somone completely new to the process of graphics it would be appreciated.

if your just starting with C++ graphics you should use Allegro (which is cross platform) and once you've mastered that go onto AllegroGl (a mixture of opengl and allegro) and the if you want you can go onto opengl.
