Re: Again with OpenGL

I think I understand the different ways it rotates, I just want to rotate one shape while another stays still

Re: Again with OpenGL

Well when I put the rotate within the push and pop it won't rotate.

EDIT: This is using the "glutMainLoop();".

Re: Again with OpenGL

glPushMatrix(); glRotatef(0.1, 0.0, 1.0, 0.0); glBegin(GL_POLYGON); glColor3f(0.0, 0.0, 1.0); glVertex3f(0.3, 0.8, 0.0); glVertex3f(0.3, 0.2, 0.0); glVertex3f(0.8, 0.2, 0.0); glVertex3f(0.8, 0.8, 0.0); glEnd(); glPopMatrix(); Shouldn't this rotate my rectangle and nothing else?

Re: Again with OpenGL

Thanks!

So, the push and pop helps matrix selection?

Re: Again with OpenGL

which object is the "glRotatef" function rotating?
How do I specify one object as opposed to another?
Do I just use the "push" and "pop" to change between objects I'm controlling?

EDIT: Evidently not.

Re: Again with OpenGL

So does view space only have an x and y, or does it have a z within the use of the library?

Re: Again with OpenGL

So, model space has the origin in the center?
And view space has its own origin... like the upper left corner of the viewing area?

Re: Again with OpenGL

So now some questions...
What, more specifically, is the point of matrix mode and projection and "glOrtho"?

Re: Again with OpenGL

I made a polygon! I did it! I made a window appear with a polygon inside of it!
Thanks, guys.
Ah, the feeling of learning something new, and visual, in programming. And without a bunch of bugs...for now.
Does it always feel this good?

Re: Again with OpenGL

Thank you.

I'm apparently supposed to put a library file inside of a "PlatformSDK" folder, but I'm not finding the folder.
Any ideas?

EDIT: I think I found what I was looking for.

Re: Again with OpenGL

Thank you.

Also, does "freeglut" work the same as Glut?

Re: Again with OpenGL

Thanks.
I'll try out that first link.

I think I tried the other one before and it didn't make much sense to me.

Again with OpenGL

I've gotten back into programming. I had done some work with SDL before, but anything I try to learn with OpenGL I don't understand. The tutorials on it don't seem complete, even the online book. How do I START? What goes at the BEGINNING of the program? How do I use a window that I've set up? How d...

Oh dear, another person dies...

I didn't know about this social networking site,
but it seems strange enough given the circumstances, and the fact that it seems like so many people in technology have been dying.
