How to un-project window point?

[zhang.jian_bin]

Given a point in window coordinate(2D point, pixel point), I need to know the corresponding point in world coordinate, or viewing coordinate.

This un-projection may results in different answers, typically the point on near plane of frustum would be acceptable.

How can i do that?

Hi Zhang,

 

Please, check the intersections examples: https://developer.unigine.com/en/docs/2.3.1/code/uniginescript/usage/intersections/

Oh, yes, I found that function in camera class: getDirectionFromScreen.
