PointCloud and particles systems

[al404]

before starting to look in babylon i was looking at particles systems in threejs i saw some examples like this ( is not mine )

http://codepen.io/seanseansean/pen/EaBZEY

you can try to change line 65 to 200.000 an still move it without issue

particleCount = 200000;

i guess from name and digging a little inside threejs code that it is drawing a point, that i guess i lighter than any simple mesh

 

in babylon i found the ability to change a mash into point with material

meshMat.pointsCloud = true;
meshMat.pointSize = 1.5;

and 2 different particles systems: ParticleSystem and SolidParticleSystem

SolidParticleSystem is a big mesh of other meshes ( and i guess it is suppose to handle a lot fewer objects ) but are ParticleSystem and material.pointsCloud similar to threejs PointCloud?

can point interact with mouse pinter, for example on click?

Hello!

you have multiple options

- ParticleSystem: every particle is a quad generated on GPU side. Pretty efficient: http://www.babylonjs-playground.com/#1RRQKC. 

- SolidParticleSystem: a specific mesh that can be picked, can generate shadows, etc...Works pretty well if you need to have complex particles: http://www.babylonjs-playground.com/#2FPT1A#9

- Point cloud: You can ask the renderer to generate points instead of triangles: http://www.babylonjs-playground.com/#RAIHJ#18

 

To interact with mouse, you can use SPS or do it manually with two other options.

At first sight, I would say that ParticleSystem or PointCloud can achieve the same result as your link

@Deltakosh I'm watching your vide on MS 

would it be possible to use the point as primitive for a SolidParticleSystem? i didn't found 

whitch other primitive would be the best choice to use to make something like a plain ( no 3D ) dot? i will probably apply a small texture

Thanks

Something like this? http://www.babylonjs-playground.com/#WCDZS#7

Here is the doc you should read. You'll see that SPS is really powerful
