Hello. I'm trying to rotate two vectors around the origin. I continue to get very strange numbers that don't make any sense. Is there anything notably incorrect about this rotation function? void rotateVectors(double rad) //Rotation must be in radians. { va[0]= cos(rad)*va[0] -sin(rad)*va[1] ; //vec...

Thanks.
I guess I'll just have to wait until a time when it clearly needs to be used.
I like getting back to programming. Making some math functions now.

Well, I'm back after a long break from programming to get back into it again. This time I've decided to stick to learning some more basics before trying to make any sort of complicated 3d program. For me this means some math. I'm using a math related book, and right now I am reading about the dot pr...

I'm still a little confused at what I would want to use the projection matrix for.

So would it be a bad idea to use the old OpenGL? I mean, is it still used professionally by anybody?

Thanks everyone. I'll keep up the research.

I've read through some of "Real-Time Rendering". Still not sure I understand it. It is all hard to understand. I see the pipeline, which breaks down into other steps, which breaks down into other steps. But that doesn't really help. I still can't figure out how to use OpenGL to do anything...

I found it through those videos too.

Saw this video...

Ok. Thanks.
I'll take a look at that text book.

I can't help but be a little frustrated when the only highly recommended book on OpenGL essentially tells me to use their own "tools" instead of actually teaching me OpenGL. It may as well open up and say, "Well, here's a book on OpenGL, and by 'OpenGL' I mean a game engine I built in...

Thanks.
I've been having trouble still getting it to work. so I decided to uninstall and install a new version of xampp. Now I get this error where it says there is not such file as "C:\xampp\htdocs\xampp\index.php" on line 2.

I looked in the files and I couldn't find where I was supposed to allow access.
I see the word "deny" written a lot, so I imagine that is part of the problem, but I hardly have an idea what any of it means.

Now I just get an Access Forbidden whenever I try to test a webpage.
