Mesh Change Event

Rhino Developer

I am writing a Rhino Plugin using RhinoCommon .NET SDK. I am trying to get an event whenever the mesh or it’s material or texture is updated. Is it possible to do that ? ( I am very sorry if it’s already discussed or documented. ) If possible, can you point to the link or sample code ?

There are a bunch of static events that you can subscribe to on Rhino.RhinoDoc, including:

// Called if an object is about to be replaced.
Rhino.RhinoDoc.ReplaceRhinoObject

//  Called when all object attributes are changed.
Rhino.RhinoDoc.ModifyObjectAttributes

// Called when any modification happens to a document's material table.
Rhino.RhinoDoc.MaterialTableEvent

// Called when any modification happens to a document's rendering content
Rhino.RhinoDoc.RenderEnvironmentTableEvent
Rhino.RhinoDoc.RenderMaterialsTableEvent
Rhino.RhinoDoc.RenderTextureTableEvent
Rhino.RhinoDoc.TextureMappingEvent

Does this help?

@dale - is there a way to get the Mesh Id of the mesh who’s UV’s changed in the Rhino.RhinoDoc.TextureMappingEvent pls? Or do you need to query the currently selected meshes?

Thanks

I guess you could query the currently selected meshes. You might need to iterate the document looking for meshable objects that are using the texture mapping id.

Thanks - I tried that and it works well.
