1. Refraction and Reflection Test Use Blender 3D and POV-Ray to render a scene in which there is only a single white solid cube. The background color of the scene is set to sky blue. to compare the rendering results.

2. Blender 3D: Cube { reflection 0, Alpha 0.35, IOR 1.55, Depth 2, Traceable off }

3. Blender 3D: Cube { reflection 0, Alpha 0.35, IOR 1.55, Depth 0, Traceable on }

4. Blender 3D: Cube { reflection 0, Alpha 0.35, IOR 1.55, Depth 1, Traceable on }

5. Blender 3D: Cube { reflection 0, Alpha 0.35, IOR 1.55, Depth 2, Traceable on }

6. Blender 3D: Cube { reflection 0, Alpha 0.35, IOR 1.55, Depth 4, Traceable on }

7. POV-Ray: Cube { reflection 0, filter 0.35, IOR 1.55, Depth 0 }

8. POV-Ray: Cube { reflection 0, filter 0.35, IOR 1.55, Depth 1 }

9. POV-Ray: Cube { reflection 0, filter 0.35, IOR 1.55, Depth 2 }

10. POV-Ray: Cube { reflection 0, filter 0.35, IOR 1.55, Depth 4 }

11. POV-Ray: Cube { reflection 0, filter 0.35, IOR 1.55, Depth 10 }
