Hi all,
I want to know if it is possible to measure the distance
between 2 random 3D points in the scene (not distance
on the screen, but in the scene) ? I want to be able
to click on a point in the scene, save its point as
point-1 , similarly click on another point in the scene
with a mouse and get point-2. Then I should be able to
calculate the distance between the points. I know
how I can get the exact screen co-ordinates by clicking on
the screen. But, how can I convert those co-ordinates to
that of the Scene ?
Please help if u have an idea.
Thanks
Tina
