Very OT: I need to learn openGL fast, suggestions?

Can anyone suggest me the most efficient and quick tutorial around ? Is NeHe the quickest one ? I basically need to be able to be able to do fog effects, 3D selections and stuff like that in a week and my knowledge in openGL is currently at 0, I know that's a bit mad but I would just need to know the most efficient and quick tutorial around, anyone has any suggestions ?

Are you seriously asking for programming advice on a hockey message board? That's like asking a nun if you can by weed off her.

Well, some people asked about different domains like hardware, software or even legal advices often, I tried my luck. You could have just as well let it die if you find it not pertinent.

one week is a big crazy to learn that sort of thing considering your knowledge is 0.

Do you have ANY programming knowledge? eg: Functions, Arrays, Loops, conditions etc?

You can try your luck at: ebook.com

otherwise, google is your friend i suppose?

No no, my knowledge in openGL is at about zero but I program in some object-oriented languages like Java/C++. I know a couple of good books but I was just asking of someone knew of a more condensed way to learn it like commented openGL code which gives a better idea than a book.

well if you have strong C++ skills you'll be fine with a book on openGL with examples. OpenGL is not extremely complicated, but there are some concepts that aren't necessarily intuitive. I learned it 7 years ago at polytechnique and didn't really like it (no artistic sense whatsoever here ) so it didn't stick in my mind. But I remember going through examples in the class book and "Adapting" them to my lab needs.

I found that for you on amazon...looks like a good book

http://www.amazon.com/review/product...By=addFiveStar

you can search google for "OpenGL book review" to see other suggestions

good luck

you could probably just find a site that has codes already all done up.

Well, the point is that I would have liked to know if you guys already knew websites with good code examples with comments, but thanks for the help !

Haha, I'm doing the "projet integrateur" currently without the infography course at Poly too, that's why I'm asking that.

Then I'm confident you can pull it off (depite what others might think )

Your best bet is someone elses project from last year. You can figure it out from there...

Yeah, I guess that could be done but most people are conservative with their codes for some reasons.

I can give you my code (if I find it).
I don't know about fog, but the 3d selection worked.

Nice thanks, give me news soon if you can, I'll give you an e-mail address to send to if you don't feel like hosting it somewhere.

SpreeEndaz, does it needs to be OpenGL or are you just looking for a way to graphical effects? Because if you're not bound to a technology, DirectX would probably be a way more accessible API.

Maybe things have changed since my college years, but OpenGL has some nasty characteristics that are hard to work with for people used in higher level programming languages. Working with stacks isn't fun when you're used to the elegancy of OO.

Well, if it was for my own app, I'd use DirectX but this is a school project and I can't really negotiate the specs, but thanks for the suggestion !

Thanks ! I can't believe you actually made a .doc to explain exactly what I needed ! Man, there's people for everything on this board and this prooves it once more.

I'm happy I'm doind the "projet intégrateur" in civil engineering, I wouldn't understand a thing in these OpenGL things.

Another way is to find someone that needs to learn C++ in a week and trade with him.

The hardest part of OpenGL is figuring out how the vectoring system works. After that it's all a piece of cake.

Wow.... 1 week?

My only advice would be to lie down, plug yourself in and ask Tank to upload the knowledge program for openGL.....

I mean, is there any real viable alternative solution?
