Opengl problem

1 Attachment(s)

Hello i'm trying to get an example in my book working. It is supposed to allow you to move the camera around in a 3d scene. It compiles fine but when i try to run it the window is destorted and i cant figure out why.

there are four files Point3, Vector3, camera.h, and test.cpp

I included them in a zip file and it is attached

The first error is in the function call to glClear at Ln. 70 in test.cpp.
Bad

glClear(GL_COLOR_BUFFER_BIT||GL_DEPTH_BUFFER_BIT);

Correct

glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

The second error is in the Camera::setShape function, where the identity matrix should be loaded before you set the matrix mode.
Bad

glMatrixMode(GL_PROJECTION);

glLoadIdentity();

Correct

glLoadIdentity();

glMatrixMode(GL_PROJECTION);

Have a nice day!
