Rotate orthographic projection scene

I have a scene I’m creating with orthographic projection:

gl.glOrtho(0.0f, 100.0f, 0.0f, 100.0f, -1.0f, 1.0f);

I’m trying to rotate the scene 90 deg. counterclockwise using ‘gluLookat()’. I can rotate the scene using ‘glTranslate()’ and ‘glRotate()’, but I’m thinking ‘gluLookat()’ would be better. Here’s what I have working. I know this is Java, but I think the calls should be the same as C, eh?

gl.glTranslatef(100.0f, 0.0f, 0.0f);
gl.glRotatef(90, 0, 0, 1);

For the life of me I cannot get anything with ‘gluLookat()’ working. The basic (non-rotated) call to ‘gluLookat()’ is:

    0.0f, 0.0f, 0.0f,		// eye X,Y,Z
    0.0f, 0.0f, -1.0f,		// center X,Y,Z
    0.0f, 1.0f, 0.0f);		// up X,Y,Z

I can get the scene rotated correctly by specifying ‘1.0f, 0.0f, 0.0f’ as the last three parameters, but I can’t get the scene translated to the right any image is clipped off…


    100.0f, 0.0f, 0.0f,		// eye X,Y,Z
    100.0f, 0.0f, -1.0f,		// center X,Y,Z
      0.0f, 1.0f, 0.0f);		// up X,Y,Z

To Translate you need to move both the eye and the camera view point center by 100.

Thanks for the response! It was close, but not quite. After rotating (e., setting the last three parameters to ‘1.0, 0.0, 0.0’, ‘up’ is now the X axis so I need to move the eye and camera in the Y axis 100 units. The final call to do a 90 deg. counterclockwise rotation is:

    0.0f, 100.0f, 0.0f,		// eye X,Y,Z
    0.0f, 100.0f, -1.0f,	// center X,Y,Z
    1.0f, 0.0f, 0.0f);		// up X,Y,Z

Thanks again!
