Marquee selection

[nekochanoide]

Hey guys .
I need to implement marquee selection (box selection, rectangle selection).
Deltakosh’s idea I found:

@Deltakosh

Yeah I would do something like drawing the rectangle with GUI or HTML then take all meshes, project their bounding box and test intersection between projected rectangle and selection rectangle

Idea looks goot to me, but instead of boundingboxes, I want to project edges of meshes and check if any edge is being inside rectangle selection.
My problem is that I am not familiar with projection at all .
Right now I am reading about this and will apprectiate any tips.

You can use the Vector.Project / ProjectToRef method to project a 3D vertex to screen space:
