The camera for the scene is setup at (0,0,4) for the eye point, with a view direction of (0,0,-1) and a view up direction of (.3,1.0), normalized, to tilt the scene so it is not all right angles. The view plane distance is 6, and the horizontal camera angle is PI / 6.

The scene has two point light sources: a white light at (-5, 5, 5), and light source with color (0.4, 0.1, 0.3) rgb at position (-3, 20, 5).

The scene contains 5 objects: two spheres and three mesh objects including a flat shaded cube and a smooth shaded cylinder and finally a smooth shaded bunny.

The scene took 433 seconds to render on my PC laptop. Rerendering it on my Mac Mini M1 took only 15 seconds!.

I added this scene to show better examples of specular highlights.

The camera for the scene is setup at (0,0,4) for the eye point, with a view direction of (0,0,-1) and a view up direction of (0, 1,0 ). The view plane distance is 6, and the horizontal camera angle is PI / 6.

The scene has two point light sources: a white light at (-5, 5, 5), and light source with color (0.4, 0.1, 0.3) rgb at position (13, 10, 5);

The scene contains 5 objects: two spheres and three mesh objects including a and a smooth shaded cylinder, a smooth shaded bunny, and a smooth shaded teddy bear.

Rendering it on my Mac Mini M1 took 192 seconds (much longer with teddy instead of cube from first scene).
