SPS Bounding Box

[Nastro]

Hi

When i click on a SPS Mesh i need to target camera on center of the SPS. But i can't get the bounding box to get center. Any ideas ? :/

Thanks

sps.mesh.getBoundingInfo()  ? http://doc.babylonjs.com/classes/2.4/AbstractMesh#getboundinginfo-rarr-boundinginfo-classes-2-4-boundinginfo-

about how to set the SPS BBox (not automatic by default) : http://doc.babylonjs.com/overviews/Solid_Particle_System#sps-visibility

Hi @jerome

Thanks for answer.

I tried 

  SPSRoom.computeBoundingBox = true;
  SPSRoom.setVisibilityBox = meshRoom.getBoundingInfo().boundingBox;

But when i call : scene.onPointerDown

I get the general bounding of all SPS not specific SPS ...

  scene.onPointerDown = function (evt, pickResult) {
    var meshFaceId = pickResult.faceId;             // get the mesh picked face
    if (meshFaceId == -1) {
      return;// return if nothing picked
    }

    if (SPSRoom.pickedParticles[meshFaceId] === undefined) {
      return;
    }
    var idx = SPSRoom.pickedParticles[meshFaceId].idx;  // get the picked particle idx from the pickedParticles array
    var p = SPSRoom.particles[idx];                     // get the picked particle

    if (IdSPSRoom_RefPiece_Array[idx] === undefined)
      return;

    var bbox = SPSRoom.mesh.getBoundingInfo().boundingBox;

    arcCamera.setTarget(bbox.center);

    arcCamera.radius = (bbox.maximum.z - bbox.minimum.z) * 1.5;

    //alert(IdSPSRoom_RefPiece_Array[idx]);
    //p.color.r = 1;                                  // turn it red    
    //p.color.g = 0;
    //p.color.b = 0;
    //SPSRoom.setParticles();
  };

It's ok. I save in a array the bounding box of mesh before and i get it after to use it and get center.

Thanks Jerome
