D3DIM converting screen click coordinates
Author
Can anyone suggest a good/best way to convert coordinates where a user has clicked on screen to 3-D space coordinates that I can use to determine what/where they clicked on?
Thanks,
Futzy
Hi,
I don''t know how to do it in 3d, but the way I did it was to take my transformed polygon and write a function called
ISPOINTINTRIANGLE(). Want a copy of it? You pass it the point you want to check, and the three transformed points of your triangle, and it''ll tell you if it''s inside.
The only problem is, I don''t know how to get at coordinates after directx transforms them, so I did my transformations manually.
Anyway, if you want the function, email me at jraptis@csmi.com and I''ll send you a copy.
