Thanks.
I bought an OpenGL book last month and I started learning 3d. All what I was able to do so far is make a human cube that rotates. I wanted to load 3d models into my OpenGL project but I was surprised that loading 3D models is unbelievably hard.

I came across this problem a while back. I would recommend checking out Assimp, it will load into memory almost every model file you can think of, and then provide the data in its own "format." I made a converter tool using Assimp so that my games could load the models in their own format without depending on Assimp.

The only problem is there isn't a lot of help available to get started with Assimp--only the documentation. If you decide to use Assimp and need help, contact me or ask the APIs and tools people.

Hope this helps!

thanks a lot. i just have one question. Can i use Assimp in commercial projects for free? or do i have to buy their product ?
the whole point of using opengl instead of using a ready game engine like OGRE3D is because I want to understand how engine are made, and maybe some day make a one. very very simple one.

I don't know much about software licenses, but on their website they refer to theirs as "liberal."
http://assimp.sourceforge.net/
http://assimp.source...in_license.html

Anyway, if you write a tool using Assimp, then I don't think you would have to worry unless you release it.

As far as help goes, there is the documentation, which you should certainly look at:
http://assimp.source...t/main_doc.html

and some tutorials:
http://assimp.source...html/usage.html
http://ogldev.atspac...tutorial22.html
http://www.lighthous...ls-with-assimp/

and a sample of my own tool: (Look down to drawing with openGL under TBC)
http://web.ics.purdue.edu/~swilkewi/portfolio.html

I also found a tool for converting to Ogre meshes if you want to go that route:
http://www.ogre3d.or...structure=Tools

I started too with 2D, my main goal was to re-code Age of Empires II.

The reason why I not moved to 3D was my laziness to learn.
One day (November 2011), I saw a video of one guy in facebook that sparked me interest in three-dimensional modeling.
I talked to him and he advised me to watch some examples here: http://nehe.gamedev.net/
And I started programming in 3D (and learning some algebra that I forgot) ...

This was the last version of my 2D engine:

And this what I am doing now:

The problem is getting started.

Wow that is very impressive. you should really keep working on you 2D engine. that is just amazing.
good luck wishyou the best.

thank you very much really. that was very helpful.
well looks like i'm moving to 3D

thank you guys all of you for your help.

I changed the url to my Assimp tool. http://web.ics.purdue.edu/~swilkewi/portfolio.html

Good luck exploring 3D!
