HI, Does anyone know how to determine the hidden object in case of 3-D projection problem while making the pre or post processing?

thanks in advance

There are methods for 3-D rendering. For example, you can read about it in http://www.geocities.com/SiliconVall...e/9955/p3d.txt

Best redards.

Thanks alot.

I have visited the websit you told me, but we wonder whether there are Fortran subroutines for 3-D rendering problem.

Best Regads

Hello Hongliang,

It may be worthwhile to try the book "High-resolution Computer Graphics Using FORTRAN 77" by Ian O. Angell and Gareth Griffith, MacMillan 1987 (ISBN 0-333-40398-3).

This 355 pages book treats the hidden line problem thoroughly and comes with many (~100) useful (FORTRAN) subroutines, including shading and surface reflection problems.

Thanks a lot.

This is the book we are seeking for.

Best Regards

Hongliang
