please review these codes

$$ Did the assignment output include a $3$D object selected from the list? $($Yes$/$No$)($Sphere$,$ Cube, or Torus Knot$)$

$$ Was the object animated making it move $($In both x and y directions$)$ within the viewing area and simulate bouncing off the walls when the edge of the viewing area was reached? $($Yes$/$No$)$

$$ Was a basic color applied to the object and was the color changed every time the object encountered an edge of the viewing area? $($Yes$/$No$)$

$$ Did the scene employ a light$-$yellow light source in a fixed position at the upper left corner to illuminate the object and did the illumination demonstrate both light and shadow on the object? $($Yes$/$No$)$

$$ Was the JavaScript $/$ Three.js code well documented $($Scale of $1-4$ where $1$ is no comments and $4$ is comprehensive comments$)$
