I would like know if it’s possible to use a vertex buffer in
I would like use ImGui for build a ui in a display viewport, ImGui not dépend to a graphic or UI library, it only builds a structure of vertices.
My problem is that after ImGui built this structure, I need to rebuild it with Rhino objects to draw them in a window. but it is slow.
An alternative solution is to use a mesh of rhinoceros, but here too it is not very useful,
The overall ImGui process is to build a vertex structure, then define a VBO and call
glDrawElements for each element.
is it possible to manipulate opengl to draw an overlay on a viewport ?
