geo memory usage

[jesse nicodemus]

Hello,

I have a few questions about memory as it relates to geo. I have noticed that geo dramatically affects the amount of ram being used. I was wondering how hybrido is handling the geo under the hood.

Is memory related to complexity of the geo, volume of the geo. or just both?

If there are two overlapping pieces of geo does hybrido take a double hit on memory by voxelizing both full shapes or does it only combine and take that combined area? My limited testing hints that it voxelizes both full shapes.

My final question is if there are some good tricks for optimizing memory usage in hybrido?

Thanks,

When talking about Hybrido memory is mainly affected by the volume, small cell sizes will increase the amount of memory used.

Your observations are quite accurate, when two objects intersect the volume is computed independently for both, although when the volumes are passed to the solver only the union of the volumes is used. Still the two volumes are in memory.

In the next major version of RF a huge improvement regarding memory used by object is scheduled. For the moment only increasing the cell size will allow you to use less memory.
