How can picked a mesh with precise

Questions

hi
how can picked a mesh with precise ?

2

Sorry @nasimiasl not clear what you need.

Do you mean with a precise parameter as in AbstractMesh - Babylon.js Documentation

3

hi again
sorry for short explain
we have parameters in intersectsMesh ( https://www.babylonjs-playground.com/#KQV9SA#0)

that work on ray cast
i need have that in picked event in actionmanager

4

So here is the actual function used in the scene:

mesh.intersects(ray, fastCheck, trianglePredicate, onlyBoundingInfo);

where:

fastCheck = false;
onlyBoundingInfo = false;
5

May I ask why you need another setup ? Perf ?

6

it is not for mouse pick right?

7

It looks like it is but I might have missed smthg, is it not what you experience ?

8

i know about raycast but all happen in scene now i wanna have pointer hover and pointer pick on exactly mesh not on mesh bonding box

9

Which should be the case with action manager ? Could you share a playground where it does not do that ?

action sample hove work on bonding box

make sample in progress

Does pickedPoint from PickingInfo - Babylon.js Documentation give you what you need?

@nasimiasl if you speak about the intersection enter and exit triggers, you can force more precision through their parameters https://playground.babylonjs.com/#J19GYK#177

try the first menu from down i feel that hovered out of face
the menu mechanism work like this demo https://playground.babylonjs.com/#9VALBN#21
but in here work perfectly

I am not sure it comes from the event as they are really precise:

See on the sphere, they really only work on the geometry not the bounding box.

Could you simplify your playground with only one menu item with a standard material to see if it can be due to the geometry builder ?

It looks like all the begining of your position buffer is corrupted and contain NaN information fixing that would solve the issue.

now that don’t have NaN
