POV 3.5 b 9.icl on PII 233 128 MB with NT 4 Sp 6

when I write such simple one-line scene:

   disc{100*z,-z 50 pigment{color rgb 1}finish{ambient 1}}

then parser parses ok and renderer renders fine
but when I change normal to z

   disc{100*z,z 50 pigment{color rgb 1}finish{ambient 1}}

then renderer work the same but parser says warning:
"Camera is inside a non-hollow object."

I have tested what min_extent and max_extent returned for both

#include "strings"
#local L1=disc{100*z,z 50 pigment{color rgb 1}finish{ambient 1}}
#local L2=disc{100*z,-z 50 pigment{color rgb 1}finish{ambient 1}}
#debug concat(VStr(min_extent(L1)),"\n")
#debug concat(VStr(min_extent(L2)),"\n")
#debug concat(VStr(max_extent(L1)),"\n")
#debug concat(VStr(max_extent(L2)),"\n")

So what is wrong ?

There is a camera somewhere on the disc, so there is nothing wrong.  You
only have to move the camera out of the way by adding one to the scene
rather than using the default position.

Seems you not read my reports carefully and makes always mistakes at first
reading :-)

I send whole scene. It contains _only_ disc and no light_source or camera
definition. So camera is default and it is at <0,0,0> and looks along z. Disc
has center at 100*z and radius 50. In any orientation it can't contain <0,0,0>.
And bounding report from last example shows it not contains <0,0,0>

You are right, it isn't on the disc (I did not check your scene, that would
take too much time if I would check every scene posted - sorry!).  However,
I don't get the warning when rendering either of the two examples, so there
must be something else in your scene, maybe via an include header INI
option?

It is not changed standard instalation.
And when I comment this disc or just remove it from scene then renderer returns
standard warning: No objects in scene. Default camera is placed properly becouse
discapear on image. So there must be something wrong. You test it with Mac,
right ? Can anybody confirm my report with windows? For me behaviour is
identical in both win compile versions.

I don't get a warning here (WinNT, beta 9)

with both -z and z as disc normal ?

strange, what processor ?
I'll check 95 at home.

I can confirm this.

I can confirm this error under W2K 3.5 b9 icl win32

Also, note that the following gives the same error (mainly making sure that
defaults are the defaults - but a hole in the disc makes no difference):

// perspective (default) camera
camera {
  location  0
  look_at   <0.0, 0.0,  10.0>
}
disc{<0,0,100>,z, 50, 45 pigment{color rgb 1}finish{ambient 1}}

Disc seems to be behaving like a plane (adding hollow to disc fixes the problem
with or without hole).

One other point - adding bounding and clipping to the disc makes no
difference...
