Considering there are clearly tons of programmers/learning programmers here I think we should make a thread where we can talk about different programming languages and help each other out, I'm currently messing around in OpenGL though I suspect if I want to make anything functional like a game I'm going to have to properly get into C++ too, feel free to post code here of stuff you're working on and need help with etc.
glClearColor(0.0f, 0.0f, 0.0f, 0.0f); glClear(GL_COLOR_BUFFER_BIT);
glLoadIdentity(); glPushMatrix(); glTranslatef(-0.5f, -0.5f, 0.0f); glPushMatrix(); glRotatef (90.0f, -180.0f, 0.0f, 0.0f); glPopMatrix();
glBegin(GL_TRIANGLES);
glVertex3f(0.5f, 0.5f, 0.0f); glColor3f(1.0f, 0.5f, 1.0f); glVertex3f(1.5f, 0.5f, 0.0f); glColor3f(1.0f, 0.5f, 1.0f); glVertex3f(0.5f, 1.0f, 0.0f); glColor3f(1.0f, 0.5f, 1.0f);
glVertex3f(0.5f, 1.0f, 0.0f); glColor3f(1.0f, 0.5f, 1.0f); glVertex3f(1.5f, 0.5f, 0.0f); glColor3f(1.0f, 0.5f, 1.0f); glVertex3f(1.5f, 1.0f, 0.0f); glColor3f(1.0f, 0.5f, 1.0f);
glVertex3f(0.5f, 1.0f, 0.0f); glColor3f(1.0f, 0.5f, 1.0f); glVertex3f(1.5f, 1.0f, 0.0f); glColor3f(1.0f, 0.5f, 1.0f); glVertex3f(1.0f, 1.5f, 0.0f); glColor3f(1.0f, 0.5f, 1.0f);
glEnd();
glPopMatrix();
I made a pink pentagon, WEEEEEEEEE! ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) Can't figure out how to get GLRotatef working though.

Purely from a C++ coding style perspective I see no reason to be "indenting" the function calls you have (indenting is normally done for code *blocks* that are surrounded by braces or for conditional expressions). You might consider using an "empty code block" to make it more express the indenting you are after though: ... glPopMatrix(); { glBegin(GL_TRIANGLES); ... glEnd(); }

I am interested in learning C++ mainly because that seems to be the most widely used language out there. I am already familiar with HTML because I've learned it some in school and have used it in creating my websites, and next year, I will be learning some Java as part of a course and will probably continue to mastery the following year. However, C++ I will need to learn by myself, so do you guys have any recommendations for me learning it by myself. My parents may help me as they both know C++ and multiple other coding languages.

I would recommend reading Scott Meyers and Herb Sutter and keeping your focus on Standard C++ always (i.e. not extensions for specific compilers such as MSVC). BTW - https://bitcointalk.org/index.php?topic=203104.0.

Just remember it's not the language that matters (okay, maybe it matters a little), it's the practices and techniques you learn from using that language. If you master the correct techniques, you'll pick up future languages faster, and produce better code and documentation.

I did some coding in OpenGL, it is pretty fun. I had to open up some of my old math books from college that I figured I would never need again. For interaction, you should first start with using a key listener. Making stuff happen based upon various keyboard keys is fairly easy.

I dunno about that, I don't think I want to use anything particularly pre-made I think the only thing I've done that's pre-made so far is use the Codeblocks OpenGL sample to get all the window setup that I need because the tutorials I've looked at are outdated with some of the stuff they have. I did notice some VK commands for all the keyboard stuff in the compiler so I'll have to have a look at the syntax involved with that so I can make stuff move. Edit: AHA! Nehe seems to be very good with this stuff and it's just what I need, IF commands ftw! ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif)

It would be really great if this got added as a sub-forum. I know it can be related to services etc. But, this just seems like a great way to break it up from the other things located in other sections, however I don't have anything to add at this moment as i'm mainly a python programmer, and learning java now.

Nobody here's programming in LOLcode? Seriously? You should all try it. Wikipedia: http://en.wikipedia.org/wiki/LOLCODEThe Hello World program: HAI CAN HAS STDIO? VISIBLE "HAI WORLD!" KTHXBYEAs you can see, its insane efficiency at any task combined with its extreme brevity makes it a must for any real coding project.

Bah, does anyone know some good tutorials that show you how to combine OpenGL and C++ while I'm searching for them myself? The OpenGL tutorials are great and I have an easy time drawing basic stuff on it now but I need to look up how to properly combine everything so I can interact with the shapes I make ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif)
