. I have created a volume texture from a set of slices of USHORT values. . The data in these slices had values from 0 to 65535. . I wrote a shader program which can get a particular pixel from the volume texture. . When the value of the pixel exceeds 2048 it does not give the right value. . I came across a site:- http://www.3dcenter.org/artikel/nv40_technik/index3_e.php where they said about a precision problem when the value goes above 2048. . I am using 7800 GTX card. Will my card also have the same problem? . What should I do to regain from this trouble. [Edited by - manur on November 8, 2006 3:21:55 AM]
