Set BoundingBox

[NasimiAsl]

how can change BoundingBox Size (manual)

i make a mesh and change a vertex position when i move camera ( camera not see bounding box ) the mesh is hidden ?

Did you try refreshBoundingInfo() ?

[NasimiAsl]

i dont want recalculate BondingBox I wanna Set it Custom

[adam]

create a new BoundingBox(min, max) BoundingInfo(min, max)?

You can try setting the minimum and maximum of the existing bounding box, but I'm thinking that probably won't work.

I'm afraid this is the only way : creating a new one BoundingBox

you can't change the current one.

[adam]

You can also just set alwaysSelectAsActiveMesh of the mesh to true if performance is not an issue and you don't need the bounding box for anything else.

If you want to set it to your own size, check this out : https://github.com/BabylonJS/Babylon.js/blob/master/src/Particles/babylon.solidParticleSystem.ts#L746

thanks @jerome

hi i use this  mesh._boundingInfo = new BoundingInfo(new Vector3(-5000, -5000, -5000), new Vector3(5000, 5000, 5000));
        but don't change anything

 

but this solve my problem

  mesh.alwaysSelectAsActiveMesh = true;

as far as I know, the bounding box is recomputed each time the world matrix changes, so setting a new created bounding box manually should be done at the right moment
