Hi eyeball,

Hi Adrians,

Closed by commit rBc271a9fa8bc4.

I agree, this should be shelved. Thanks for having a look though. :)

If the bug report contained info what happens, there wouldn't be any fun in solving it : )

@lamoot, it was at least enough so I was able to understand the issue ;) Fix incoming

It's already more information, but it's still unclear what is the unwanted result that occurs when following these steps. Does Blender crash, freeze, UI artifacts appear, save window doesn't open, lag?

I'm having the same issue with the same equipment. Works for a while then they drop randomly. I have three nodes with Ubuntu 14.04 with 4x nVidia GTX Titan Black GPUs each. One may drop or all may drop. Blender is running fine on slaves when I look at them, and nothing in logs on Master that describes the reason. I've tried both 2.72. and 2.73 on both Master and Slave.

Wow!
How fast! Thank you, team!

Hey Jiri!

• The idea behind find_first_points() was to evaluate the function only at "lattice points" to cache them in the hash table. The function evaluation (bvh traversal and actual densfunc()) take 95% of the time in polygonization, so any gain made in this area contributes a lot to speed. But, to be honest, I just coded it this way out of laziness temporarily :-) I could make a version with 26 directions and check how it behaves. If all values will be cached, the speed shouldn't be much worse, and surface accuracy is number 1 priority after all.
• I don't exactly know what you mean by caching the surface? Updating only the part of the surface that was influenced by a moving metaball or something else? This could be a serious improvement, but not in the case when all metaballs are moving (eg. a fluid simulation). Could you explain it more?
• Sorry, but I don't have the energy to look at these papers right now (very tiring day at uni, a lot of science done :-)). They look very interesting at first glance. Will check them out in detail later.

Replace i by cam_idx in loop.

can we raise this back to normal because it will take a some time for us to test

i am sorry i had to do something and thought this was all that was needed

Wow, that is a huge scene !
