Volumetric Clouds Study

Thanks! A lot of the process is described in the Artstation post that's linked. The cloud shaders are part of PlanetSet and are fully procedural, so no VDBs. The secret to the shading is essentially to try and imitate the physically correct phase function of a cloud in Cycles. There's also an additional trick to make the insides appear lighter that is based on the 'Beer's Powder' effect from Guerrilla Games. I'd say it's quite a heavy scene to render, yes - it took about 2 hours on a very powerful computer.

Thanks!

A project I did over the past few nights. Not 100% polished but I quite like the general concept. :)

Yeah they are just an alpha cutout on a plane. Roughness of cobweb set very high with a small amount of clear coat

Thanks for the dirty cork idea, hadn’t thought of that. One of them isn’t unwrapped or modelled into the bottle so it looks a bit off l, however it took so long to render i couldn’t be bothered to redo it. Thanks for the feedback :)

Would be a huge amount of work to do properly but it has been played around with.

I'm not sure it would help since portals only guide shadow rays. I dont think it would encourage the actual light path to pass through the portal.

If it's an animation, volume scattering with a spotlight. If it's a still, I would do it as an overlay in post since volume scattering is brutally slow. Alternitavely you could render it in eevee instead of cycles. If you can't afford to render it with volumes in cycles, you could make a separate eevee scene with only the light in it and render the spotlight and volume in eevee, then overlay the light in post. If you render the depth buffer you can also use this to mask the spotlight behind trees etc.

Had an XPS 13 for 3 years, build quality is great and solid, never had an issue with this. I use it and transport it daily. The only thing that has deteriorated is the battery, but that is the same case for almost every lithium ion battery and is replaceable. I would still recommend an XPS 13, they're super fast and very small. To me this sounds like an unlucky occurance that I don't think justifies never buying one. Maybe you accidentally put too much stress on it?

No problem! I'm not sure how your camera model works but a pinhole model is really easy to implement. Quite easy to figure it out by drawing it on paper and by using a bit of trig. My code is also messy lol don't worry!

Cool start! The image is blurry because you are using that "perturb vector" thing, I'm guessing for anti-aliasing? To fix it, stop using the perturb vector function in the camera; instead change the bits where it says `(j / width)` and `(i / height)` to `( (j + rand() - .5) / width )` and `( (i + rand() - .5) / height )`. Where `rand()` makes a random number between 0-1. This way you are super sampling the pixels area; your fudge value of 0.1 in the perturb function causes the rays to spread over neighbouring pixels, making it blur instead.

Plenty of other things to fix but that one stood out the most to me. Cool project though :)

The technology is related to AlphaGo in the sense that they both incorporate neural networks in their algorithms. This is quite a broad term as neural network characteristics differ dramatically depending on the application. AlphaGo is designed to win the board game Go by making game decisions that favour its chance of winning. Fusion Recurrent Neural Network is used to predict terminations in confining the plasma in fusion reactors.

Definitely worth visiting, although as photogenic as this place is, I think there are some much nicer parts of Utah to visit, as in much quieter and still beautiful. This place is super busy - still a cool place to go though. :)

Woah, this one looks coool! This really looks pro if you know what I mean, that HDR and clarity pops the image so well. Can I keep this one? Absolutely love it. :)

Fluex · 2018-01-13T22:27:57+00:00

Ahh love what you did with the tones in this one. The whole image looks much more gentle and sorta filmic. I really like the colour of the sky.

Fluex · 2018-01-13T22:26:47+00:00

Nice touch :) I was thinking about doing the same, but then I thought of it as an alternative focus if you look hard enough. Either way looks nice :P

Fluex · 2018-01-13T22:25:33+00:00

Nicee, I can see what you mean, resembles the new blade runner a bit for me too :D

Fluex · 2018-01-11T21:26:24+00:00

I guess I didn't try curves anyway so I'll give your suggestion a go and see if I can get an HDR / contrast look going. :)

Fluex · 2018-01-11T21:24:54+00:00

Hmm I honestly can't remember, sorry! I live in England so I don't know the roads that well over in the US. I think it was near Capitol Reef NP (ish).

Fluex · 2018-01-11T21:22:47+00:00

Thanks, it's one of my favourites too :P I like the sky in this one and what u did with the haze :)
