OpenGL Translation/Rotation over C++ Example

// Push everything 10 units back into the scene
glTranslatef(0.0f, 0.0f, -10.0f);

// Translate our object along the y axis
glTranslatef(0.0f, yLocation, 0.0f);


// Rotate our object around the y axis
glRotatef(yRotationAngle, 0.0f, 1.0f, 0.0f);

// Render the cube

// Flush buffer to window

//Start opposite rotation if the angle >360 or < -360 if (yRotationAngle > 360.0f)
yRotationAngle -= 360.0f;
