<p class="MsoPlainText" style="margin-left:36.0pt">> 3) replace the painter that draws the actual primitives with a new one which uses the interop array of vertex Ids so we can do the depth sort witout retransferring stuff to and fro every frame.<o:p></o:p></p>
<p class="MsoPlainText" style="margin-left:36.0pt">><o:p> </o:p></p>
<p class="MsoPlainText" style="margin-left:36.0pt">> The painter chain is already setup to do depth sort on the CPU, so I'd only need to add a cuda version with the interop setup and then add a new primitive painter (or some kind of painter that does the final
draw instead of the existing one - might need to send the colours+opacities via interop too to avoid trouble retrieving them in the custom painter).<o:p></o:p></p>
