3D position of mouse pointer

[Tyler Heath]

Hello,

my goal is to get 3D point position under mouse using the depth buffer. I am just starting with this kernel.

Thanks for any help.

There is IView_DG.ScreenTo3D, but I did not find it very useful.

What you probably need is selection. See the Pick sample. C# PickForm.GetObjectAt() does the job with IPick_DG.GetEntityAt(), which returns both the entity under the mouse and the point on its surface.
