Hey,
as you can imagine out of the Headline, i'm trying to solve a large number of objects with the bullet solver in houdini.
(The task is to compare bullet with a solver written on my own).
Now i am doing some memory tests and found out that the memory usage which bullet has, is not growing linear with the number of objects.
Here some measurements:
Static object: grid with 6400 Spheres on it.
Tests:
Dynamic Obj. – Mem Usage
12 – 1,1 MB
98 – 110 MB
980 – 811 MB
5600 – 23.299 GB
8000 – >32 GB
Does anyone has a idea why?
I should go into detail about this in my Thesis and i have totally no clue why bullet behaves that way, in this special case…
I attached a example file.
Thanks in advance
