<div dir="ltr">I worked on point cloud support last summer for architectural viz firm Floored. That was in blender the modeler, not BGE really. Rendered as simple GL_POINTS with diminishing size based on distance. Biggest model we had was 17 million points (position + color) which ran ~20 fps on a decent laptop.<div class="gmail_extra"><br clear="all"><div><div class="gmail_signature">Mike Erwin<br>musician, naturalist, pixel pusher, hacker extraordinaire</div></div>

I had to involve LOD system, streaming(libload) and spatial partitioning of the scene and I'm able to visualize over 2 milion points, represented either as cubes(at far distance) or "halo" faces with various colors(at close distance), where at the close distance it has to be possible to click on a point and get some information. I haven't tried more than 2milion, but I believe BGE could handle even more.

Hello everybody, <br>
<br>
with the help of some contributors (<a href="http://www.b2fh.org" target="_blank">B2FH</a>,
<a href="https://asaip.psu.edu/" target="_blank">ASAIP</a>), I am working on a
project for scientific visualization of Big Data, in particular for
astronomy.<br>
The project is called DeDaLo (shortly described <a href="http://www.b2fh.org/DeDaLoProject/tabid/507/Default.aspx" target="_blank">here</a>),
and will help scientists to work in real time with 3D data sets.<br>
<br>
We are using Blender and python, and are really interested in the
BGE future. <br>
At the present our effort is only on developing a demo of what
DeDaLo can do, there are no resources to work on BGE code itself.<br>
<br>
After this premise, I would ask you about a feature I've read of <a href="http://blenderartists.org/forum/showthread.php?256512-Unlimited-Detail-in-the-BGE" target="_blank">here</a>:
Point Cloud for BGE. To display hundreds of thousands points is
something complex, and if you have meshes (faces), it's almost
impossible. Is there any proposal about Point Cloud in GE?<br>
<br>
Thank for your time,<br>
Roberto<br>
