Hello!

I'm trying to make a 3D game with LWJGL and right now I got the movement basics in 2D (moving a cube upwards when pressing "W" and such...) but now I want to move the camera so I get a nice 3D view. I'm trying to do it with gluLookAt()  but it just don't have any result at all... I've drew the cube at 0,0,0 and I wanted to go a bit far so I can see it completely but gluLookAt does nothing. I don't actually know exactly after what MatrixMode I have to write it, MODELVIEW or PROJECTION? >.<

I'm using this:

1  
2  
3  
GLU.gluLookAt(0.0f, 0.0f, -5.0f,
                 0.0f, 0.0f, 0.0f,
                 0.0f, 1.0f, 0.0f);


I've tried using it after

1  
2  
3  
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glLoadIdentity();
glMatrixMode(GL_PROJECTION);


and after

1  
2  
3  
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glLoadIdentity();
glMatrixMode(GL_MODELVIEW);

but no one works. I've actually tried using gluPerspective but I need to change the view's angle so...

I've also tried to use glRotatef(30.0f, 1.0f, 0.0f, 0.0f) and glTranslatef(0.0f, 0.0f, 5.0f) but had 0 effect xD

I need a bit of help here! Help please Smiley



edit: So i searched thru google (i did that before "-.-) and finally find a piece of code that worked well for me:

1  
2  
3  
4  
5  
6  
7  
8  
glMatrixMode(GL_MODELVIEW);
       glLoadIdentity();
       GLU.gluLookAt(0, 1, 5,
                     0, 0, 0,
                     0, 1, 0);

       glPushMatrix();
       glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );


And after that put all the cube's code.
