Subject: Re: Slicing large STL files

We are currently working on a Memory Efficient Slicing Algorithm for STL files.
The program mainly alleviates the memory bottle-neck caused by STL file size during slicing.
For the time being, the largest STL file I sliced was 38MB having 767256 facets using a 64MB RAM under Win 95. Sorry I could not remember the time taken!!.
However, as of now it can only generate a custom layer format (CNT) in ASCII format which is very much similar to CLI. I will incorporate the CLI output module in near future.

If you are still interested in having a copy of our program, please contact me.

    Hello all,
    Could anyone offer any advice on how to speed up the slicing process of 3D Systems' "Maestro"?
    I am trying to zslice a 19" * 19" * 21" QuickCast pattern, and by my estimates it will about 7 days just to slice the darn thing. I believe I am running out of RAM and the disk swapping is slowing down the whole process. We are running an SGI Indigo2 R10000 w/256Mb RAM. The file in question is only about 16Mb in size and 335 500 triangles. Any input would be greatly appreciated.
