Box vs circle vs sphere in sop combined with instanced particles - performance

Beginners
1

Good day,
If i use a SOP Box combined with instanced particles (so each instanced particle is a sop box), performance is great. If instead of a box I use a circle, performance is worse. And if I use a Sop Sphere then performance is reaaaally bad. Why this dramatic difference?

And given that using a sphere is so difficult because of performance (Im using an RTX 3090 of Nvidia, and 160000 particles at the moment), is there other ways to take the SOP Box and make it curvy or round? Using a SOP noise I can make it pointy and go crazy, but what if I want to do it curvy? round? how can I do it? without using a SOP sphere which seems to go so bad in terms of performance

thank you :slight_smile:

Thats the reason for the drawbacks. More points = More computing.
What I like to do in alot of cases is to use point-sprites instead of a geometry using pointsSpite material. They are super cheap compared to real gemoetry. But you losse scaling in the process.

@alphamoonbase very interesting thank you, point-sprites mmm I see, is that something i can create with sop to enter it into the geo node and use it for the instanced particles? and are they basically just points? but are they round points? because my final objective is to have some kind of round particle
