hey, what's the difference between "glVertex3d" and "glVertex3f"? I just saw it in another code snippet and I was wondering if it had to do with the coordinate variable types.

@TheGodzilla1955 The only difference is the type of argument they accept. glVertex3d accepts higher precision GLdoubles as arguments, while glVertex3f accepts lower precision GLfloats.

@steff385 Any C++ IDE will do. You could even write it in notepad, but youd need some way to compile it

[steff385]

Do i have to use Visual C++ Edition?

@mittrekkie Thanks much. love your vids!

I like that, i think his target listeners are expierienced programmers with no practice in graphic development.

These tutorials are boring.(i don't mean that they're bad, just boring.) you speak too professional and that makes people bored. you should throw in a joke or something every now and then. I've seen some c# tuts and they we're un-pro so I learned it very fast.

I learned the hard way the importance of comments in my freshmen year when I was working on a geometry project. I ended up remaking the project about five times because I could not remember what all the code was supposed to do.

So please, fellow programmers, since you can not guarantee a lack of glitches, put as many comments in as possible.

Your movies are awesome. It's so much better watching movies rather than learning from comments.

Keep it up! :)
