Title: Caustics Series (latest; No.008 - Deep Dive - Page 2)
Post by: DMerz III on March 16, 2021, 07:01:57 AM
Going to start a new personal work challenge for myself involving caustics in an effort to further hone my knowledge and abilities there to control this phenomenon.
Will be continuously updating this thread with the latest.

Here's No.001

Back with next experiment in the series - this time adding in some motion.

Goals for this piece;
- try out some movement (slight-elastic type motion) on the refractive object
- experiment with colorful lights and understand their effect
- trying out multiple light sources to 'paint' the room with the caustics

Here's the short animation + a still frame.

 :) No.003 is another animation; you can see it here on youtube; https://youtu.be/x-PuRQrS500

Learned quite a bit during this exploration.
Here's a couple of stills from the animation;

Maybe this is NFT material? They look so awesome!

 :D Glad you like it, hopefully I'll have some more coming in the near future here, flurry of client work at the moment. TO BE CONTINUED!

Working on No.004 - currently rendering the frames. Here's one of them - just straight-up out of KS10.

Hopefully will have the animation up soon.

And here we go with the full-animation. It does loop, although haven't figured out if that's possible on youtube yet.  ::)

So this one deals with a continuous curiosity of mine - optical lenses. I think they're so cool, and I wish I knew more about them, so I've been studying up on the principals and....quickly got over my head with it. But I did want to attempt something that dealt with what I had gathered and this was the result of my playing around. Probably will be an on-going theme in my caustics series as I think there is just so much to explore here!

Attached is another still frame with a tighter shot.

Genius work keyshot is the best caustics renderer i have seen for a while! with spectral capability

I can watch this animation in an endless loop with some relaxing music all day long. Great job!

absolutely amazing !!!
I already liked the stills, but this is breathtaking!!
it is not only the result, but one can see, that there is a lot of thinking behind it !!!

masterpiece!

Title: Re: Caustics Series (latest; No.005 - GlassCliff)
Post by: DMerz III on April 28, 2021, 06:33:01 AM
No.005 - bringing back some of the concepts from the others into a product-focused scene. Also experimenting with scattering medium to pick up on the spot-light beam ever so slightly - as a happy accident, this also created even more subtle texture in the caustics.

You really shouldn't put your glass so close to the edge like that, David. Someone's bound to knock it off.  ;)

Post by: DMerz III on April 30, 2021, 10:14:18 AM
 ;) @tgs808 - I'd like to think the caustics are little ion thrusters and giving the glass a little extra support.

Back here with a revision to this scene - I had made an error with the liquid body which is a long story, but here's an updated image.

If someone doesn't knock it off, it's going to fall off if you fill it up much more! :o
Oh, and the caustics look pretty sweet! 8)

Dramatic deviation from my typical work - this latest installment of my caustic series explores Volumetric lighting, and bouncing a beam between mirrors (and getting the reflection of that beam to be visible in the mirrors, which is oddly, not something that's easy to achieve in other engines). Keyshot 10.2 was used here, but I believe Keyshot 10.1 would have also worked.

Absolute gold, David. Such a great example.

Re-worked this whiskey glass render once again - this time with a closeup to see more of those beautiful lacey caustic patterns below. Made some adjustments to the scene overall including reducing the 'bloom' from the previous glass, adjusting the liquid color to my liking, tweaking the volumetric beam, and adding some more definition/crispness to the caustic pattern.

Technically and visually speaking your work is really  interesting, this an excellent technical demonstration of physical light capabilities of keyshot, great job :)

Caustic Series No.007 — just in time for summer.

This one was built specifically to test the A6000's VRAM - went insanely small with the displacement triangle size to crank up those polygons.
Base mesh was modeled in Blender brought into Keyshot 10. Trying to recreate ice crystals/frost has been something I've been wanting to attempt for a while, and pretty pleased with the results. Helps when you do not need to worry about polycount!

Another rendition for the Caustics Series. No.008 - Deep Dive
Using my special technique to generate a density map (.vdb) in Blender which is driving the bubble geometry node in Keyshot 10.2 here.

Rendered w/ GPU mode on the Nvidia RTX A6000 in high-resolution 4096px²
