Bugs  |

====  | 
|
| 44 | 3  | 
* bad sphere/box transmisivity  | 
4  | 
Inside-out transition is ignored as every second intersection is ignored to avoid duplicit  | 
|
5  | 
intersect points. This solution should be replaced by moving ray origin a little forward, which  | 
|
6  | 
should work as well and without side-effects.  |

- optimize construction: use box-shape intersection instead of bounding boxes of shapes  |

* absorbtion of refracted rays in dense materials (can be computed using shape distance and some 'absorbance' constant)  | 
| 44 | 20  | 
* implement efficient AABB-ray intersection using Plucker coordinates  | 
21  | 
* generalization: Camera "shader" (ray generator), surface shader and maybe light & background shaders  |
