picking polygon meshes with overlapping bounding boxes

[mojojojo]

Hi,
 

I have some meshes, created with PolygonMeshBuilder. They're not overlapping, but their bounding boxes are as you can see in the attached screenshot.
I want to achieve pixel perfect picking for those. Using scene.pick without fastcheck for some reason still picks those meshes by bounding box. (In the attached screenshot - the green mesh is getting picked instead of the purple one) Any ideas?

Thanks

Hi again @mojojojo.  I set-up a quick playground...  http://www.babylonjs-playground.com/#1BIQIC#4

None of the picking stuff is installed, yet, but I have a couple things scheduled this morning, and don't have time to flesh-out the testing playground right now.  Maybe mojo or others can flesh it out into a full-blown test scene for this issue.

If not, I'll do more fleshing/testing on this... a bit later.  I wonder if high-precision bounding boxes are allowed on mesh built with PolygonMeshBuilder.  hmm.  Interesting issue.  BBL

Hi @Wingnut. 

I've setup some actions on top of your playground -

it works perfectly... 

Maybe there's something wrong with my polygons...  I'll investigate and update you further.

Thanks

Hi guys,

quick update for anyone interested in this.
Problem was in the way I created the Path2 for the PolygonMeshBuilder ->

Previously, I added the points of the polygon, using Path2.addLineTo(x,y).
Once I switched to Polygon.Parse, as in demo playground it all worked out.

Thanks
