I need to examine this closer. The ray conditions have proven to be a 
tricky business before (which is probably also why this change slipped 
in there in the first place; I'm pretty sure it is unintentional indeed).

Can someone submit a GitHub issue for this?

I'll do it in bit and post a pointer when done.

For those compiling at home, see the branch (off master) at:

https://github.com/wfpokorny/povray/tree/fix/photonNoImageIssue

if you too want to set up a regular pull of the proposed ray.h change 
into your version of POV-Ray for testing/immediate work.

I never built a source on Windows; and at the beginning of 'my problem
no_image', i don't really know that the change can be, or may be, in the code.

I only 'flying' in SDL.


Best regards

Hello,

I followed your link to the source 'povray-fix-photonNoImageIssue'
I would like to know it was possible to receive a built of this version from
you.

I was interested in the vs2019, the 'builting' seems to me a test too
consequent.

Thanks

Albun

Hello,


I would like to know it was possible to have a built of this version for
Windows10, from you.

In a hurry to get the new stuff I see! :-) I was busy with real/other 
life than POV-Ray for a couple days. In any case I don't read the news 
groups every day. Sometimes, I intentionally avoid it for a time so I 
stay focused on my current task...

Offering a general response to your posts of the last few days, POV-Ray 
development doesn't have a somehow paid - or equivalently motivated(1) - 
core of developers unlike some other open source projects. Everyone's 
doing it primarily as a hobby. This means both that there is a lack of 
folks wanting - and able - to do the uninteresting grind of release/test 
work and often that those few are otherwise busy. I'd say today there 
are only two active such developers - and I'm not one of those.

(1) Master/PHD thesis work, new widget / world change believers. A few 
crazy folk perhaps... :-) Once in a blue mood someone will fund specific 
work in POV-Ray, but this tends from what I've seen to be funding for 
specific features and not the day to day review/test/release work.

To your specific question, no, it's not today possible for me to provide 
a release for Windows10. I'm a linux user for starters.

That said Christoph has created some github windows release build 
mechanisms I don't understand, but see. Especially if something 
something similar exists/can be created for (ppa-ish) for Debian/Ubuntu 
builds, I might - someday - dig into doing personal releases from my 
playpen of code branches and ideas.
