  height_field Bug (Message 1 to 7 of 7)  
From: Kevin Ellis
Subject: height_field Bug
Date: 1 Jul 1999 21:45:32
Message: <377c19bc@news.povray.org>
While rendering the included file at 640X480 resolution with no antialiasing
and the imagefile as compressed Targa, I get the message:

Illegal grid value in ddu_traversal().

This does not seem to affect the render, but the problem disappears if the
scaling is changed from 0.007 to 0.006 (see file for line) or if the
resolution is changed.

I am running POV-Ray v3.1e.watcom.win32.r1, on Windows 95 with a P133 and 32
megs of Ram

  Please don't post here unless you are completely sure it REALLY is a bug.
Try povray.general instead.
  And don't send binaries outside the .binaries groups.

  Regarding to that message, see http://iki.fi/warp/povVFAQ.html#ddatraversal

Try http://www.students.tut.fi/~warp/povVFAQ.html#ddatraversal instead
of the URL I gave (there seems to be a problem with iki.fi).

The original link you gave worked fine thanks. I shall also put a link to it
on my own page to stop anyone who passes by also causing bother. Again very
sorry.

Kev

I now know what's causing the problem. It's not iki.fi but the web browser.
  What happens is this:

  The location field has an URL and a parameter (separated by the #). What
netscape (at least 4) does is to send a request for the URL (without the
parameter) and when it gets it, it searches into the given page and locates
the section specified by the parameter.
  But iki.fi doesn't send a page. Instead it redirects the browser to another
location.
  Here comes the "bug". When redirected, netscape loses the parameter, so
when it gets the page from the redirection, it doesn't have the section
parameter anymore.

  What browser are you using? Perhaps IE works better in this case...

A rather annoying "Bug".

I am using IE 5.
