Today while tring out HDRI for the first time with MEGAPOV 1.1, I ran
across something that I don't think should happen.
Normally it's quite possible to map images onto a sky_sphere, but when I
tried it with a HDRI image (using image_map, just as shown in the
documentation), MEGAPOV crashed every single time.
sky_sphere {
pigment {
image_map {
hdr "HDRI/kitchen_probe.hdr "
once
map_type 1
}
}
}
Using map_type 7 did not effect the outcome either. I can provide the
rest of the file as well if necessary, but it rendered perfectly just
before I added the sky_sphere HDRI (see "Star Wars Battle Droid" in p.b.i)
Changing the code to use a finite sphere fixed the problem. I'm running
MEGAPOV 1.1 on WinXP SP1 using a fresh download of the kitchen probe.

unless you have a space at the end of your file name this is wrong.

Sheesh.
I wouldn't have expected it to crash because of that. I guess that's
what I get for not proofing better.

What do you mean by "crash"? If it just gives an error message, that's
not crashing.
If it, however, truely crashes (ie. the OS gives you something like
"this program has performed an illegal operation" or "segmentation fault"),
then that's a bug which should be reported.

It crashes and i assume the reason is the .hdr extension is not listed
in gPOV_File_Extensions and Locate_Filename() can't cope with this. But
it should be obvious why this has never been a problem in the past
(since it is quite rare you specify the wrong file name).

Bad, bad to assume things are not likely to happen ;-)

Sorry, but this is nonsense.

But of course you can't be bothered to explain why?! :(
It is quite unconstructive to criticize someone's statement without at
the very least explaining why you believe it to be so.

It might be a good idea not to say nonsense if you don't have a better
explanation and did not look at the code. Adding
,{{ ".hdr", ".HDR", "", "" }} // POV_File_Image_HDR
in fileinputoutput.cpp solves the problem - you get the expected
Parse Error: Error opening HDR image.

No, not here. But there are places you cannot see (but Christoph and I
can).
