All of these were at a resolution of 640 pixels wide by 512 high. All scenes used a view plan distance of 10, and a horizontal camera angle of 45 degrees.
Each scene has a central mesh object with a sphere on each side.
The camera location and angle was adjusted slightly for each scene to make it more appealing, starting with an original camera position of 0,0,2 with a view direction of 0,0,-1(negative z) and a view up vector in the positive y direction.
This looks a bit like Mickey Mouse. The camera is at (0, 0, 2). The camera view direction is (0, 0, -1). The view up direction is (0, 1, 0). The mesh model is unmodified (no tranlsation or rotation).

The camera is at (0.5, 0, 2). The camera view direction is (-.7, 0, -1). The view up direction is (0, 1, 0). The mesh model is unmodified (no tranlsation or rotation).

The camera is slightly elevated and looking downward. The spheres are moved further out on X axis to make space for teapot. The camera position is also moved farther back (positive Z direction) to account for the larger size of the scene.
The mesh model is unmodified (no tranlsation or rotation). The camera is at (0, 2, 3). The camera view direction is Vector3(0,-0.3, -1). The view up direction is (0, 1, 0).
