I would like to know if there is a way to get an Ids buffer/visibility buffer.
I see for example that in the API there is the possibility to get the z buffer
Or, how can I create my own buffer with different objects?
My knowledge stops at the use of
Perhaps you can step back and describe what problem you are trying to solve?
No doubt this is to get a selection map to make it faster to determine what object was clicked on in the viewport. See the custom rotation plug-in @kitjmv has been working on. It would eliminate the need to use
GetRenderMeshes and do expensive ray hitting he has been asking a lot about recently.
And some of the related posts RhinoObject.GetRenderMeshes, bug? , Render mesh topology , How do I always switch to wireframe when moving the view? . I thought there were more, but can’t find them now (at least a post with a huge amount of objects in and trying to get render meshes and do fast ray intersection and determining overlapping objects).
Thank you @nathanletwory, you saved me many minutes of English translation!
That’s right, my goal is to quickly retrieve the object under the mouse cursor.
I don’t need a lot of precision, but it has to be fast, very fast.
Yesterday I found a solution with an “empty” display mode (
DisplayModeDescription). No shadow, light and others:
And using a
But the performance improvement started to show when 30 objects were under the mouse, producing (when meshed) over a million faces.
To avoid overloading the
IdConduit, this technique requires me to keep calculating if the objects are visible in the view and extracting the meshes with
It’s a shame because Rhino has the full vertex buffer to display objects on the screen.
So I want to know if there is a way as easy as
Rhino.Display.ZBufferCapture to get map Ids (or visibility buffer).
With a depth map and identifiers, it would be easy to calculate an intersection. not precise, but fast.
In the end I wrote my long blabla in English… /
