What is the simplest method of displaying a GeometryModel3D as a point cloud? (HelixToolkit / SharpDX / DirectX)
I am using HelixToolkit.Wpf.SharpDX to display a mesh in the 3D viewport. A requirement I have is to display any given mesh as solid, wireframe and point cloud.
The solid and wireframe implementation is simple, since the GeometryModel3D object provides the FillMode property in order to switch between them.
However I cannot find a simple way to switch the display to a point cloud. What I mean by this is that each vertex should display a small point. Does anyone know of a way to do this? I need the switching of the display to occur very quickly, just as switching between solid and wireframe is extremely quick.
Example images below:
As far as I know you cannot simply toggle between Mesh and Point representation. You have to transform your mesh model to a PointGeometryModel3D and use its Point collection to visualize.
