Different QuadRemesh results between Rhino UI and Rhino.Inside API

Rhino.Inside

I’m finding that the Mesh.QuadRemesh API in Rhino.Inside produces a different mesh (different face and vertices count and Normal’s are missing through API) results than running the QuadRemesh command in the Rhino UI, even with the same target object and parameters.

My goal is to replicate the manual Rhino UI results deterministically within my Rhino.Inside C# application.

Rhino version: Rhino 8
Rhino.Inside Nuget: 9.0.5 beta
Source Mesh : 92 vertices, 100 faces
Rhino UI Result : 106 vertices and 103 faces with normal
Rhino.Inside API: 116 vertices and 114 faces without normal

Question:
Am I missing an extra step that the Rhino UI performs automatically?

When a mesh gets added to a document, Rhino will perform a few operations such as computing normals which will alter the computed mesh slightly.

Thanks for the response @Trav, My main focus is that the number of vertices and faces I am getting are drastically different through the API compared to the Rhino UI.

before you call quad remesh translate your mesh so that its centered on the world origin from its bounding box center.

Thanks @Trav , It worked!
Now I am getting the exact count of vertices and faces.
