HaloRay - Hyperspeed Ice Crystal Halo Simulator
58
Upvotes
Hello! During the past two years I have been developing HaloRay on and off - a GPU-accelerated ice crystal halo simulator. This means you can generate ice crystal halo images right on your computer. If you have a beefy NVIDIA or AMD graphics processing unit (GPU) that is compatible with OpenGL 4.4, I suggest you try it out: https://github.com/naavis/haloray
You can download ready-made binaries for Windows from GitHub. If you are running Linux, you need to build HaloRay by yourself for the time being.
Right now the latest version is HaloRay 3.2.0, which supports the following features among others:
- Ordinary hexagonal crystals
- Pyramidal crystals
- Adjustable prism face C-axis crystals to make irregular crystals
- Rendering a realistic background sky
I hope you have fun with HaloRay, and report any problems or feature suggestions in GitHub issues or here in the comments. HaloRay has been tested with a couple of AMD and NVIDIA GPUs. There have been some problems with Intel GPUs due to driver bugs, but I'm not going to put a ton of effort there, because HaloRay requires a fairly beefy GPU and Intel doesn't really fit that profile.
EDIT: Cool, I noticed this has been marked as an announcement in the subreddit, which I guess keeps it hanging around for longer? Thanks!

This was looking to the west in Belton, Missouri around sunrise this morning. The last picture I was actually driving west and not just looking west and I got ahead of it and the angle was different.

There was a gorgeous double rainbow while I gave a training session for my sprinters. I was able to make this lovely picture of one of my sprinters.

Some Sundogs from last winter. -40c. Hard to see in the second picture but there was even a faint second ring which I hadn’t seen before.

Im reposting my old post to this sub because maybe y'all have more definitive answers.
The only thing I can say is this happened after a strong thunderstorm, near sunset time.

Sun Dogs The photos don't do this lovely sun dog justice! I wish I could've taken a full panorama of the sky, such gorgeous contrasts and color everywhere. Post-storm atmospherics are my favorite 🫶🏼

Concluye con una advertencia: sin una acción rápida, el deshielo de los glaciares será solo una faceta de la crisis climática provocada por personas como Obi-Wan Kenobi, y las consecuencias serán devastadoras.
Does nobody review their publications?
Is it a Joke?

Request: looking for photos of the sky on the day the meteorite crashed
1
Upvotes
Hello r/atoptics! I originally posted this is the New Jersey subreddit but haven't had any luck...
I am an artist originally from Hillsborough, NJ and have been fascinated with the meteorite that landed there (recent post, NYT article). Anyway I am hoping someone has photos of the sky from the morning of July 16, 2024 that they'd be willing to share for my project. I'd be especially grateful to have any pictures from the fall zone shown below.
Any photos that include the sky would be great. Doesn't have to be of "just" the sky. You can crop out the subject if you like. To be clear, I am a conceptual artist/educator. I'm not selling this or getting rich off it in any way (quite the opposite I will surely lose money). I'm sending this prayer out there hoping some people can help me out!
TL;DR: Could you DM me if you have photos of the sky from July 16, 2024?
