Rubik's Cube creation in OpenGL and C#

I am really new to OpenGL and I have a question about some code that I wrote. I am writting a Rubik's Cube program using C# .NET and OpenGL. I can generate the 27 individual cubes and I can use glRotate and glTranslate, but only when I call the resize event. I know that I am definitly doing something worng. Any help, or code about how to move the actual cube(s) not just the camera would be great! Thanks.

HERE'S what i have so far:

I took a look at the first website that you suggested, and the code in the website isn't even C#. The second website doesn't do much becuase i don't need to know how to solve it because I have Prolog code to do that. My real question has to deal with whether or not OpenGL has a way of storing the points that I generate and second a way to move the cube that I create, not just moving the camera around the object.

I will only award point for suggestions in C# on how to successfully move my cube. I'm sorry, but that's what i really need. Thanks.

These two tutorials look like they may help me out a bunch. I will take a look at them in the next few hours and get back to you. Thanks.

Those two tutorials helped somewhat. Is there anyone who is experienced with structures and arrays within structs that could help me out with some code or tutorials??

thegilb

Just explain in more detail what you want to know and I will tell you.

Okay. Here's what I'm going after right now.
1.) I am starting to make a struct for each of the 27 cublets. The struct will have a unique ID, an array that stores that face colors for the cube. and an array for all the points of the cube.

2.) I'm having trouble wrapping my mind around the array that needs to store all the points and then manipulating the points.

3.) I plan on using the face color array and the points array to move the slices of the cube just like you are playing the game.

Thanks for all of your help by the way!
