c0fc061834 Don't set the focal/aperture on the constructor and use a dedicated method for that. 2020-03-17 00:28:56 +00:00

9849c16f66 Couple of small optimisation 
Add option to build for gprof
Do not build by default with the renderstat (they have a reasonable impact on performances)
Separated created ray and castedray in the stats
Trying to force some simple function to be inlined

aacd4f6c9e Make BVH and Octree to not flatten the world before parsing 
It may help a lot on some scene that already use groups.

So each exiting group have their own BVH or Octree in.

It does help a lot on already organised scene like the Christmas balls.

Allow inlining the function helps a bit!

424d58c59b Octree Optimiser seems to work. 
Well.. There are a couple of weird things happening, need to investigate, but it's not that easy when scene start to be complicated :/

5da0c10182 Started working on "world optimiser" base class. 
The idea is to reorganise objets to take use of the them to prevent most object to be intersect if they are not likely to be on the ray path.

15a861802a OBJFile now use group instead of it own list. 
Change the group function to find group by name, and now name group when needed, and change tests to use group name instead of number.

Also now the default group is the base group, not a separate group.

Bonus: Add a destructor to cleanup memory
Added a function to get base group. OBJFile will still behave as a valid shape, but now we can skip it in the generated world by adding the base group instead.

Code is now cleaner.
