Query filter MeshGeometry.YES not working

EvanReese

I want to filter a query param for only mesh vertices. Here's what I have:

annotation { "Name" : "Mesh verticies", "Filter" : EntityType.VERTEX && AllowMeshGeometry.YES && MeshGeometry.YES } definition.points is Query;

But it's highlighting MeshGeometry.YES with the message "Unhandled enum type MeshGeometry". I get this even if it's the only filter enum I use.

Looking a the documentation for UI queries here it seems like it should work since MeshGeometry is on the list. What am I missing?

You could try this:

annotation { "Name" : "Bodies", "Filter" : EntityType.VERTEX && AllowMeshGeometry.YES && !BodyType.POINT }
definition.entity is Query;

Oh wait, never mind. I was just checking against the origin..

Looks like it isn't supported by annotations yet, or maybe unhandled? All of the other ones specify that they can be used in annotations.

Perhaps it's only to be used with:

qMeshGeometryFilter(queryToFilter, MeshGeometry.YES)

You could always use some edit logic to get rid of non mesh points as they are clicked.

I'll fix the doc — thanks for pointing out.

Thanks Michael. I'm not sure what "unhandled" actually means. I considered the Editing Logic solution, but I hoped to avoid it. I'll probably just leave it as is for now.

EvanReese

@ilya_baran I hope I'm not bothering you with unimportant things, but the list of possible filters for Query Params in the documentation here does include MeshGeometry so at some point it should be made to work, or removed from the list.

Just following up here for posterity. After looking at the Constrained Surface code in the standard library, it seems like we can filter out non-mesh geometry with !AllowMeshGeometry.NO which is what I was going for.

MichaelPascoe

Shouldn't !AllowMeshGeometry.NO be the same thing as AllowMeshGeometry.YES or am I missing something?

It feels like a double negative, but it seems like AllowMeshGeometry.YES will is "all bodies, including mesh ones" and AllowMeshGeometry.NO is "all bodies excluding mesh ones" while !AllowMeshGeometry.NO seems to be "only mesh bodies". There's a venn diagram in there somewhere.

MichaelPascoe

I guess this means that AllowMeshGeometry.NO isn't the opposite of AllowMeshGeometry.YES… 😩
