Project Bifrost preview

A lenti videóban láthattok néhány klipet arról hogy hogyan is áll jelenleg a Project Bifrost azaz az Autodesk Naiad. A videó eleje csak marketingrizsa, 6:40-től kezdődik a lényeg.

Naiad for Maya vs. Bifrost

A következő sorokat a Max Underground fórumról schmidtelem ide a Naiad fejlesztőjétől:

Hello everyone,
It seems many people are arriving at incorrect conclusions in regards to Naiad and Bifrost, and how they relate to Maya and Max. Naiad was a standalone, node-based software that did fluid simulation (liquids in particular). You had to use a separate app (Naiad Studio) to make Naiad graphs, and then export the sim output into Max. “Project Bifrost” (which is a CODE-name, btw, not necessarily the actual product name) is also a standalone, more general, node-based software that will do fluid-simulation – and much more, in time. Bifrost does not know about Maya. There isn’t a single line of code in Bifrost that directly uses the Maya API. Maya, on the other hand, can be made to know about Bifrost. That’s how we, as a test, integrated Bifrost into Maya. It follows that Bifrost could easily be integrated into other DCCs, be made as a standalone product, ported to the iPad – you name it. One of the many strengths of the Bifrost architecture lies in the fact that it’s “product agnostic” and that it can “go anywhere”. What we showed at the Autodesk User Group last week was the results of our experimental Maya integration. We have to focus on one product and do it right, and the decision was to go with Maya. I understand that users of other products such as Max may feel disappointed, but before you condemn Autdoesk to the 7th circle of hell you should take note of two things:
1. Autodesk has NOT said that Maya is the only DCC that will ever run Bifrost. Just because Maya was chosen does not mean it won’t appear elsewhere.
2. Even if Maya, in the end, is the only DCC to allow Bifrost FX authoring, is that really all that different from Naiad Studio? Nobody was complaining that you had to use Naiad Studio to author Naiad graphs, then export the sim output into your favorite DCC, and go from there? How would this be vastly different? Maya can, in the worst case, be viewed as a “better” Naiad Studio. Use Maya for making your Bifrost FX graphs – then export the sim results into Max and go from there. This is what you did with Naiad Studio + Max, and you can do it with Maya + Max. I understand your frustrations, but I wanted to give you guys a bit of perspective :-)

Best wishes,
Marcus Nordenstam

Any claims that “Bifrost is part of Maya” are false claims.

Naiad 0.6.1

Íme a Naiad hattyúdala, amit a tegnapi levélben is említettek. Az fxguide-on lévő cikk szerint a két fő fejlesztőt és a technológiát vette meg az Autodesk nem magát az Exotic Mattert. A Naiad nem folytatódik tovább, mint Autodesk Naiad, hanem a technológiát építik be majd valamelyik Autodesk-es programba (programokba).

Naiad 0.6.1 demo - Coming Soon from Igor Zanic on Vimeo.

 New Standard Operators

•     HD (experimental) - allows a selective uprezzing of a lower-resolution fluid body (an "SD" body).
•     Aerodynamics (experimental) - fast gas/smoke/fire solver operator (can, however, exhibit some grid artifacts)
•     Hydrodynamics (experimental) - fast liquid solver operator (but does not always converge)
•     Particle-Mesh4 - 4th-generation particle surfacing code (fixed many of the Particle-Mesh3 artifacts, yet sacrificing none of the great detail)
•     Body-Read - read various file formats and make a corresponding body (or bodies)
•     Sphere-Mesh - make a volume body directly from a sphere
•     Tile-Expand - add more tiles around a body

Changes to Existing Standard Operators

•     Dynamics (no more energy spikes etc - see General Improvement at the bottom)
•     Body-Write / Body-Terminal
•     Combust (burn map, NEL expressions, etc)
•     Drag (accepts NEL expressions)
•     Particle-Splash-Emit (emission radius, pure ballistic)

New Naiad Buddies

•     The Naiad Buddy for Alembic (Compiled for Linux only; full source-code available for Windows)
•     The Naiad Buddy for Houdini 12 BGEOs (mesh, particles, and volumes)
•     The Naiad Buddy for V-Ray (mesh and particle export)
•     The Naiad Buddy for 3DS Max

Updates to Existing Naiad Buddies

•     The Naiad Buddy for Krakatoa - PRT reading now implemented in Body-Read
•     The Naiad Buddy for Arnold - using Body-Io mechanism

Bug Fixes

•     Under some circumstances, parameters with sliders would get incorrectly clamped - this has been fixed.
•     Crashing when using certain NEL expressions have been fixed.
•     Particle IDs were inconsistent and duplicates were possible - this has been fixed.
•     Naiad Studio crashed when invalid parameter references were present.

General Improvements

•     Overall, Naiad 0.6.1 is a more optimized, memory-lean, and awesome version of the Naiad 0.6 release.
•     The Dynamics operator had severe problems with very thin layers of fluid in contact with a moving solid.  This would cause violent "explosions" and   "energy spikes" where fluid particles would go flying off in unnatural ways.  This has been one of the long-standing problems with the Naiad solver -   and we are pleased to announce the issue has been fixed!   The underlying numerical codes have been redesigned and rewritten, eliminating this artifact.
•     Particle-Wet-Emit had problems where wet particles were "left floating around" in space.. This op has been rewritten and behaves significantly better now.
•     64-bit integer support for point and triangle channel import
•     The documentation has been overhauled to ensure all the operator docs are correct and up-to-date.  The Application Notes have been expanded to include Houdini buddy 12 docs.

Autodesk Naiad

Szomorú hír terjed a cg kapátorok körében: az Autodesk megvette tokkal vonóval a Naiadot. Mennyivel másabb lenne a hír, ha azt írhattam volna hogy: The Foundry Naiad, nemde??

Dear Naiad customer,

Please be aware that Autodesk has acquired the Naiad fluid simulation technology in order to accelerate their research and development of
simulation technologies for visual effects.

The Naiad technology, along with the engineering expertise of the founders of Exotic Matter, are anticipated to benefit not only Autodesk’s Digital Entertainment Creation solutions, but also Autodesk research into cloud services for the Media & Entertainment industry.

Your involvement has been crucial to the success of Naiad and I would like to thank you for supporting Naiad and being a part of the development of the technology.

As part of the Naiad technology being acquired by Autodesk, you need to be aware that:

* After Naiad 0.6.1 is released, all further Naiad development will cease.
* The current maintenance term will be the last one offered by Exotic Matter. All maintenance contracts will be terminated after the current term expires.
* The full source code for Naiad Studio, Naiad Command Line, and all Naiad Buddies will be included as part of the Naiad 0.6.1 release.
Due to the development transition to Autodesk, Exotic Matter support for open-source code will no longer be provided.
* New Naiad licenses are not available through Exotic Matter. Inquiries should be directed to Autodesk.

I am very excited about the future of the Naiad technology. It is anticipated that certain Naiad technology may find its way into future Autodesk offerings and we look forward to working with you to make this happen.

Sincerely,
Marcus Nordenstam

UPDATE: nem folytatják, mint standalone, hanem a technológiát beolvasztják a programjaikba. 

In an effort to accelerate Autodesk’s research and development of simulation technologies for visual effects, Autodesk has acquired the Naiad fluid simulation technology from Exotic Matter.

Exotic Matter’s founder and CEO, Marcus Nordenstam and Chief Scientist, Robert Bridson have joined Autodesk. Robert Bridson also will continue as a professor of Scientific Computing/Computer Graphics at the University of British Columbia.

Autodesk will not continue to market and sell Naiad as a standalone product but it is anticipated that certain Naiad technology may find its way into future Autodesk offerings. As of this time, there are no new product or offering announcements pertaining to the Autodesk software portfolio.

It's expected that Exotic Matter will contact its existing Naiad customers and provide information on how support will be handled. These customers can also still contact Exotic Matter through existing channels.

Vertigo Digital - BBC Frozen Planet AR

Áprilisban turnézott az USA-ban a DVD megjelenés apropóján a legújabb David Attenborough film augmented reality-je, amit a Vertigoban csináltunk. Ha jól emlékszem szűk egy hónap alatt raktuk össze (úgy, hogy mellette másik két project is futott), szóval egy kicsit belehaltunk a 4x800 frame-be (az assetek legyártásáról nem is beszélve).

Naiad - Boundary Layer R&D

A Boundary Layer node segítségével egy adott volume (jelen esetben a teáskanna) a folyadékra gyakorolt hatását lehet megadni, amint az alábbi videó azt nagyszerűen szemlélteti.

Naiad 0.7 - HD node

 

Az új 0.7-es Naiad egyik újdonsága lesz az HD node, ami a particle-detail node-al ellentétben nem csak térben felsűríti az alacsony-felbontású szimulációt, hanem új részleteket is visz bele.
A bal oldalon az alapszimulációt, a jobb oldalon pedig a HD node hatását láthatjátok.
