Thank you very much for help.

Yea I know this is not side step I just wanted to keep the same movement direction after rotating the scene. Letš say I just want to move to one direction by the vector I have above. I Multiply it...

Ok I know about vectors and matrices, used them in opengl sometimes but now have problem with that.
Let's say I have vector and matrix.
I edit the matrix every time the scene rotate like this

...

alright thanks I will check that out

Hi.
Have some problems with geometry and imagining the 3D movement. I have a game where you can move according to camera angle forward or backward. My problem is when I want to move the character...

Hey everyone. (Merry Christmas btw)
Just a simple question. I am working on collision detection and I am not sure about some things.

1) When I have a level with exact number of object, do I have...

Ok so I use that loop and instead of that calculations use matrix multiplication to the vertex or vector.
Have to check more about that.
Thanks for help

Hi it's me again.
So I learned sth about matrices but still don't know how to use them for this. I think it is not possible to change matrices during the polygons drawing. So how can I use them?...

Yea heard about them :D. Thanks for advice. I will look at that.

After some edits I ended with this but it is not working either.



case GLUT_KEY_RIGHT:
int i, xo = 20, yo = 2;

angle += 0.1;

for (i=0; i<=object.vertices_qty; i++)

Hi guys.
Need help with something.

I have imported model and I need to rotate part of it.
