Hello,
iam using gluUnproject function to retrieve the object coordinates from the screen coordinates.
when i click on a point (2,2,2) i get the output from the function as(2.218335,2.226619,-0.000000)
when i click on a point (3,3,3) i get the output as (2.218335,2.226619,-0.000000)
when i click on a point (4,4,4) i get the output as
(3.079899,3.084041,-0.000000)
when i click on a point (5,5,5) i get the output as
(3.079899,3.084041,-0.000000)
why is there such a discrepancy in the actual values and the returned values of the function??
is it the nature of the function itself or there is some other problem with my code??
i want to retrieve atleast the x-coordinate more or less exactly??
plz help me ,may be with any other possible solution.
thanking you,
vamsee.
