I want to highlight particular segment of mesh .
I am having a 3D model mesh in helix toolkit .What I am trying to do is , on mouse move I found the particular segment of mesh and I want to differentiate it without re-drawing this on my mesh . I don't want to overlay this segment on my Mesh . The re-drawing makes my software slow. So ,what I need is, how could I highlight this particular segment in mesh without redrawing them . I am using Helix toolkit in C#
