Fast Simulation of Viscous Fluids Using Position-Based Dynamics
HTML-код
- Опубликовано: 2 мар 2015
- Viscous fluids are ubiquitous, and reproducing their damped motions has been in demand for many applications. The most prevalent
approach to simulating viscous fluids is based on the Navier-Stokes equations and necessitates viscosity integration. However, to
simulate viscous fluids in a numerically stable manner, using explicit viscosity integration severely restricts time steps and requires
an excessively long period for computation. In this paper, we propose a novel particle-based Lagrangian method for efficiently
simulating viscous fluids by adopting position-based constraints. Our method uses the geometric configuration of particles for the
positional constraints to approximate the dynamics of viscous fluids using position-based dynamics; thus the method can plausibly
generate their motions while allowing for the use of much larger time steps than those previously adopted in the viscous fluid
simulations. We also propose an associated boundary-handling scheme for position-based fluids to precisely specify boundary
conditions for the constraints. Additionally, we reproduce elastic deformations of materials by controlling the constraints and
incorporate thermal conduction into our framework to simulate resultant changes in particle properties and phase transition in the
materials. By adjusting parameters, our method can encompass complex motions of fluids with different properties in a unified
framework. Several examples demonstrate the effectiveness as well as versatility of our method.

I love how the artifacts on the elastic ball makes it looks like it boiling
That part with the melting ball was really impressive!!!
GIVE ME A DAMN BREAK!

kE?
so many ways to simulate poop of various consistencies
And colours!
Yep
This is actually really good. I think I should watch it again.
Worth every second of your and my life
This is very satisfying to watch.
Very satisfying to watch in quarantine
not melted chocolate, *MOLTEN* chocolate
*Smelten*
*Smult*
This needs to be some sort of real-time sandbox game.
Dogs when they see an unpooped carpet:
I love videos like this... it's more satisfying than real life. XD
This is art, and a very one moving one :'))
No idea what I'm watching, but I like it.
Amazing, really amazing!
This is actually quite interesting.
I loved it! I think you could make so that the temperature goo would be lava. Make so that when hot, it is red and emits light. When it gets colder, lower the light and make it purple to obsidian, then black, idk.
Thank you for not making it brown.
God that rubber ball was just amazing and felt so satisfying too.
0:43 when the computer doesn't know how to fluid
why did they goo a rabbit? is it like a right of passage for physics sims to use that rabbit?
Just an example of a complex surface, I guess
As a student of Ocean Engineering, I can confirm that our proffessors religiously use rabbit as a model in their simulation.
I, too, shall follow in their footsteps.
Are teapots still a meme in computer graphics or am I too old now?
Teapots are used for rendering tests, rabbit is used of physics tests.
but why? do you mean that it is like a standardized test so you can see side by side?
very good so far but a new minor things are needed to break past the uncanny valley into straight realism.
Very impressive indeed. Great job
tell me about what is your GPU or CPU Processing size
Great job!
I like these these are really cool
It all makes sense now.
0:15 after Taco Bell:
wish software did you use to create these models ?
Any software uses this type of elements?
That bunny had a fun time
S t o p
Is this make with unity?
pretty cool
pretty realistic :)

how did you make this?
the art guy maths. Look into the paper, there is everything to recreate this method.
What?!?! people dislike this!

japan doin the next big thing in dating sims i see
came here from daily dose of internet’s comment section
pls don’t h8 m8 ur clapped same
xd
Same😂
Me too😂
Is there a source code download? I want to run or render on my computer. Thank you very much!
U can in 3dsmax and tp6
can u offer the file which can run on the 3dsmax or tp6? Thks
Nope!
These next 20 years are gna be both amazing and awful
this needs some cool music
in here b4 this goes viral for no reason
is this realtime
Start says 'sped up 2 to 4 times' so no, but not by much.
but its possible with flex phyx
no,nononono
neat

Hi 2015 me
so silent
Why did I click this

No pero si

whahaat is it with these fluid simulations and fucking _rabbites?_
Why is this in my recommended
I said ewwww to the colered liquid
Da wae
maybe because it is [BLEEPED]
I got here from a domics video, what about you?
