BeginSceneEdit takes ages to execute

[acasta69]

So the solution is to add:

Code: Select all

 if (isnan(ray->o.x) || isnan(ray->o.y) || isnan(ray->o.z) || isnan(ray->d.x) || isnan(ray->d.y) || isnan(ray->d.z))
               return false;

in EmbreeAccel::Intersect() function in src/luxrays/accelerators/embreeaccel.cpp file

I have updated the source with your solution and the build is now deployed.
Can you please check if it's ok?
