<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hello folks<br>
<br>
I am displaying particle datasets in the range of 0.3-3 billion particles<br>
<br>
Taking one dataset of 368,135,844 particles loaded as a PolyData with a single cell and a Poly-Vertex, with the default Point Rendering representation, the Unix "top" command shows that ParaView uses 13.8GB of memory. Expensive, but fair - I suppose. (No scalar
attached, just coordinates).<br>
<br>
Switching on to OSPRay Point rendering, I get into massive swapping, and when the dust settles, I get interactive rendering, and ParaView uses 43.5 GB of RAM. That's about 30GB for 368M particles.<br>
<br>
Is this a fair memory consumption?<br>
