 Bugs
 ====
- * concurrent read? (concurrent write should not occur)
+ * bad sphere/box transmisivity
+   Inside-out transition is ignored as every second intersection is ignored to avoid duplicit
+   intersect points. This solution should be replaced by moving ray origin a little forward, which
+   should work as well and without side-effects.
 
 Future Plans
 ============
+ * namespace
  * kd-tree:
    - optimize structures
-   - optimize construction: do not use bounding boxes of shapes, instead implement box-shape intersection
+   - optimize construction: use box-shape intersection instead of bounding boxes of shapes
    - optimize traversal -- no std::vector
    - save/load
- * textures (3D procedural, pixmaps later)
- * update Python binding: Camera, new classes
- * namespace
+ * textures (3D procedural, pixmaps)
+ * update Python binding: Camera, other new classes
  * stochastic oversampling
  * absorbtion of refracted rays in dense materials (can be computed using shape distance and some 'absorbance' constant)
+ * implement efficient AABB-ray intersection using Plucker coordinates
+ * generalization: Camera "shader" (ray generator), surface shader and maybe light & background shaders
