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,
