Listen to mouse events for creating a selection box

[beckmx]

Hello guys, I am reading the docs and I would like to create a rectangle from the mouse selection on a plane only, does anyone happen to have an example or similar? I saw this class but not really sure how to use it https://www.csharpcodi.com/vs2/2157/helix-toolkit/Source/HelixToolkit.Wpf/SelectionCommands/RectangleSelectionCommand.cs/

One quick way is to project all models' bounding box/bounding sphere inside current view frustum onto 2D screen space. Then compare the projected bounds with your rectangle. If you want accurate selection, then you have to compare each triangles of models.
