Multiple Vertices and great perf ?

[Nastro]

Hi Everyone !

I have a new question for you

Actually i need to create a lot of vertices like this : http://www.babylonjs-playground.com/#1NYPJD

And i need to have the most fps is possible

I check a little "Solid Particle System" but i don't know if it's for me.

The most important is i need to select all object. All object are unique. So the merge is not a possibility :/

Any ideas ?

Thanks a lot

It sounds to me like SPS is your best choice.

It's exactly a mission for SPS

or instances

or mergeMeshes ... about this last one, I don't know if the passed meshes are disposed by the function or not

[EDIT] the answer is here : http://doc.babylonjs.com/tutorials/How_to_Merge_Meshes  with the parameter disposeSource

I don't get why you have still 164 meshes and 164 draw calls in your scene since the meshes are supposed to be disposed

Would this help if Nastro needs to use a random color for each box?

[jerome]

nope

In this case, the SPS would be the last solution.

ok, I guess I understand what happen in your PG http://www.babylonjs-playground.com/#1NYPJD#1

Have a look at the line 117 : you call mergeMeshes in a loop, so it creates many many meshes... so your FPS drop

You might construct all your 164 meshes, populate an array with them, and finally only call once mergeMeshes() to get a single mesh.

I am a big believer in SPS. They are saving my bacon and FPS. Currently using over 15,000 of them. You can be creative with them. 

They are handled individually, and you can also have fun with UV texturing as Jerome can attest to.

Thanks a lot for answers.

@jerome i think that SPS is a good solution i will try.

Thanks guys : @chicagobob123 , @adam, @Temechon, @jerome
