Hello everyone
I tried to use SPS in my code to increase the rendering speed, but when I used SPS for nb more than 4000 I got the following error on my page:
this is my PG for 6 points :

and my final model for about 8000 points can be seen in the below screenshot :
I think this is a question for @jerome, but as your PG works with a few points it may be difficult to diagnose.
Also, have you tried to comment point.dispose(); (just in case it is still needed afterward)?
The global SPS performance is directly related to the global number of vertices.
The sphere mesh has quite many vertices as a SPS model. So multiplying 1 sphere by 8000 can make a really big final mesh.
I suggest that you reduce the sphere model number of vertices with {segments: 3} for instance, or that you use another model (a billboarded planar quad ?).

If you just want to render points, the Point Cloud System could be a better choice than the SPS.

Thanks a lot.
thank You so much. 
so If the PCS is better then I try to use it. Thank you for your recommend.
It’s not better or worse, but I think it fits better your needs : point rendering.
Thank you so much
