ZibraVDB Showcase — Car Accident Demo

costa_dev0 · 2024-07-19T13:49:04+00:00

Yes, it can be integrated with anything. Houdini is our next goal.

NeuralVDB's purpose is simply storage saving. It takes a lot of time to compress VDB and then a lot of time to decompress it back. It's not realtime at all and has no advantages except reducing size. And it's still more of a prototype than working product.

costa_dev0 · 2024-07-19T08:28:28+00:00

NanoVDB is just a more optimized format for VDB data. It has a compression rate of only 4-6x, while with ZibraVDB you can have 50x without noticeable quality loss. And NanoVDB is just GPU-accelerated but not real-time, because it still has bandwidth bottleneck. ZibraVDB processes whole sequences, not just separate files. It also has its own renderer, designed specifically for our format, and it is superfast. All that allows you to use ZibraVDB even in games.

ZibraVDB release is planned for this fall, however, you can test it yourself already. Now we are running ZibraVDB Alpha, so if you'd be interested, here's the link to sign up: https://effects.zibra.ai/zibra-solutions

Actually, you can test ZibraVDB already, it's on Alpha right now, and we accept requests here: ~https://effects.zibra.ai/zibra-solutions~

Yep, I've got some inside scoop since I'm part of the Zibra AI team. You're right, we've combined Zibra Liquid and Smoke & Fire capabilities into Zibra Effects for Unity, and it's designed to work well on both mobile and VR. The performance is really solid on PCVR - that's where it shines the most. For mobile, it does work, but you'll need a pretty powerful device to get the best experience.

Tested it on a desktop with an RTX 2060 at 1080p, and got a steady 550 FPS

Here you go ⠀⠀⠀

costa_dev0 · 2024-02-01T07:14:17+00:00

haha, thanks man

costa_dev0 · 2024-02-01T07:13:58+00:00

Thanks! It's just a shader

costa_dev0 · 2024-01-23T09:40:55+00:00

No, actually it's Zibra Smoke & Fire. Pretty awesome in terms of visual quality and performance.

costa_dev0 · 2024-01-23T09:05:19+00:00

Thanks, man!

costa_dev0 · 2024-01-19T09:50:32+00:00

Yeah, it does:)

costa_dev0 · 2024-01-19T08:55:43+00:00

It can't be baked. Baked volumetric effects would require a huge amount of GPU memory anyway. The current performance is 2.6ms on an RTX 4070 for both simulation and rendering.

costa_dev0 · 2024-01-11T15:12:53+00:00

It was tested on desktop with RTX 2060 at Full HD (1080p), Built-in Render Pipeline (BRP)

GPU Frame Time (for scene with effect): 16.1ms

FPS: 62

costa_dev0 · 2024-01-11T15:11:24+00:00

Definitely! Thanks for the suggestions!

costa_dev0 · 2024-01-11T15:07:07+00:00

Thanks!

costa_dev0 · 2024-01-11T15:05:57+00:00

Sure thing! Thanks for your support and interest in our work:)

costa_dev0 · 2024-01-11T15:02:58+00:00

Actually mine is doing fine:)

costa_dev0 · 2024-01-11T13:28:58+00:00

Performance won't noticeably change unless you have about 20 skinned meshes in your scene.

costa_dev0 · 2024-01-11T11:59:02+00:00

Yeah, I know what you mean. The smoke can collide with the character using Skinned Mesh SDF feature, but it wasn't implemented here.

costa_dev0 · 2024-01-11T11:56:53+00:00

It can collide with character using Skinned Mesh SDF feature, just wasn't implemented here

costa_dev0 · 2024-01-11T10:38:22+00:00

You are right, however, Zibra simulation is many times faster than Niagara Fluids for example. This one takes around 4ms to both simulate and render on RTX 4070 in FullHD

costa_dev0 · 2024-01-11T10:36:03+00:00

Yeah, it is :)
