Crashing when Saving Poly Data (like STLs), Dealing with Big Models

Hi All,

Thanks for your feedback.

lassoan,
These are my specs (taken from the last Problem Report)
Model: MacBookPro11,3, BootROM MBP112.0138.B18, 4 processors, Intel Core i7, 2.3 GHz, 16 GB, SMC 2.19f12
Graphics: Intel Iris Pro, Intel Iris Pro, Built-In
Graphics: NVIDIA GeForce GT 750M, NVIDIA GeForce GT 750M, PCIe, 2048 MB
my virtual memory is 9.9G, minus reserved VM space is 8.0G
I am using Slicer 4.9.0-2018-01-07, though I have a couple older versions on here too.

The dataset I’m using came from a micro-CT with 2024 pixel panel, though the dataset was cropped at processing so isn’t quite 2024^3. I down-sampled this dataset to 8bit jpeg and the total dataset is 323.3MB. The .nrrd volume from this stack is 921.8MB.

As for using Closed surface rule to decrease poly count, I can’t get that far. I have to hit “create” first, and seconds after the model is created, Slicer crashes.
update just found that by holding the “create” button I can access the decimation factor without creating it first. I am trying it out now.

hherhold, 65 million triangles! I am impressed! Hopefully I can make that work too!

muratmaga, if it took 10 minutes, then it is possible I’m not giving it enough time. The rainbow wheel stopped spinning for me after a few minutes and I just assumed it was done, but that’s when it would crash after hitting save. Perhaps the rainbow wheel is misleading and it is not in fact done processing?
