<p dir="ltr">Nice work, the viewport GSL should be getting a upgrade shortly if I am not mistaken, also, I wonder about using a geometry shader using HG1s hack , and pass all the points in a single draw call?</p>

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>
