Why Pov (3.5RC6, I do not have 3.1 on my system) does not issue a warning
when using a media in a non hollow object ?
Not that I make that mistake very often anymore... Just wondering...
Povingly,
Philippe

It does. Unless your object is hollow, of course.

I just re-re-checked : it does not :'-(
Neither under Windows (pov 3.5.beta.RC6.win32, win2k pro sp2, athlon
1.2GHz 256MB RAM) nor on Mac (pov 3.5 build 0167, MacOS FU1-9.1,
CarbonLib 1.5, PowerMac G4 450MHz 256MB RAM).
Should I post this to p.b-t or is would this be a feature request ?
Povingly,
Philippe

It only gives a warning when the camera is inside a non hollow object. I
think it always was this way but imho it would also be good to issue a
warning if media is used inside a non hollow object.

I have just tried simple script:
// SCRIPT
box{-1 1 interior{media{ }} hollow off}
// END
with additional Warning_Level=10 in CommandBox to be sure nothing is missed
all warnings outputed in message window are:
Warning: No pigment type given.
Scene contains 1 frame level objects; 0 infinite.
Warning: Camera is inside a non-hollow object. Fog and participating media
may not work as expected.
Moving box about z*10 to not contain camera removed second Warning.
I have also tried this with default media from Insert Menu and still no
message about media in non hollow object.

Which is the default, btw.

Which is the warning we are talking about and which is given as expected,
right? Or am I missing something? I am not aware of any other non-hollow
object warning that involves media and exists in 3.1 ...

and megapov0.7

No, I thougth it would be nice for new users if Pov issued a warning
when a scene specifies a media for the interior of a non hollow object.
something like :
box{
-1, 1
material{
texture{pigment{color rgbf 1}}
interior{ media{Media}}
}
// would be much better with hollow somewhere in box
}
could perhaps issue a warning, even if it is legal and will behave as
expected (for an experienced user).
I knew the "camera in non hollow object" warning and it is that one thes
made me wonder about a "media in non hollow object" warning. I was
pretty sure there isn't one in Pov 3.1, that's why I posted here and not
in p.b-t.
I know it is a feature request (and that it is a bit late for that), but
I thought it is a simple one and one that could alleviate the
support/complaints mail charge for the team.
Povingly,
Philippe
