+ * bug in octree - black lines in center of image
 
 Future Plans
 ============
+ * changing main ray tracing algoritm to more flexible architecture with a Sampler object:
+  - update all demos for new Sampler/Camera architecture
+  - enhance Sampler to support oversampling and subsampling as before
+  - rewrite pthreads
  * namespace
  * kd-tree:
    - optimize structures
