Slicing fails with more than 10M vertexes or 3M faces #804

Open loelkes opened 10 years ago

Hi, the slicing process fails if there are more than 10.000.000 vertexes or 3.000.000 faces on the buildplate. Cura / the slicing engine seems to need more tahn 4GB of RAM at this point and crashes, so this looks like a typical 32bit-limitation ???

Theese are the last log lines from the SteamEngine in case of fail:

Reading mesh from socket with 10459347 vertexes
Loaded from disk in 5.164s
Analyzing and optimizing model...

Sometimes it says

Unknown exception

This is the maximum i was able to get with Cura. 

Reading mesh from socket with 8883435 vertexes
Loaded from disk in 4.415s
Analyzing and optimizing model...
Face counts: 2961145 -> 2942019 99.4%
Vertex counts: 8883435 -> 1471389 16.6%
Size: 98.533000 88.165000 93.223000

I use Cura 14.03 on Windows 7 (64bit).

It's not that strange that it cashes; The model is f*ckhuge. Cura makes a simplification of the model up to a few micron anyway, so a model that big won't increase the quality of the machine paths. I can strongly recomend using smaller models.

Most likely a memory issue. Cura puts all the verts in a hashmap, which can get really big with so many points. A 64bit build of the engine might work but that does add a lot of complexity.

I am surprised that you managed to load so many triangles in the GUI, which is usually the first to give.

I am installing a second SSD in the workstation. I will report how far i got with the 64bit version :-D
