The channel is about cool graphics and physics I am into.

Based on "stable fluid" simulation it is realized fluid like metamorphosis of the pictures. Distinct densities of fluids which are placed in a gravitational field correspond to different colours of the picture. Due to distinct densities fluids begin to mix. So called Rayleigh-Taylor instability.

Von Karman Vortex Street
Переглядів 37 тис.8 років тому
Animation of Von Karman Vortex Street created by 1, 2 or 3 cylindrical obstacles. The flow is made visible through violet dye or given different colors for clockwise (yellow) and counterclockwise (green) vortices. Fluid is simulated by solving Navier-Stokes equations with "stable fluids" method of J. Stam adapted for GPU implementation and extended with vorticity confinement http.developer.nvid...

The program that simulates a bunch of pendula with different frequencies (depend on length of the pendulum). Real experiment presented at ua-cam.com/video/7_AiV12XBbI/v-deo.html
2D Fluid Simulation

The program simulates viscous fluid in a 2D box, by solving Navier-Stokes equations. Algorithm is taken from http.developer.nvidia.com/GPUG... Grid: 600x600.
Is this 2D ?
Yes
mind = blown

This is scientifically valuable -- can you share your code?
Code is not clean enough to share it)) I used this article developer.download.nvidia.com/books/HTML/gpugems/gpugems_ch38.html
That was beautiful!
Hi did you publish these results in a paper? Could you please add the link to the paper if you had published it?
I used this article to code this developer.download.nvidia.com/books/HTML/gpugems/gpugems_ch38.html
I did not publish these results. It is famous fenomena)
Put obstacles arranged in a logarithmic spiral pattern in an airstream, and see what happens!
Amazing. Are there static imagines of nested tori available a well? The concept of nested tori is the essence of sensible comparative morphology. A series of static pictures of the formation of three nested tori would be very helpful in expressing to others these realization. Jim
Hi. I didn't know about any applications, actually. I got the equation from the article about Hoph fibration which I am a big fan of. There are lots of animations and pictures of this mathematical construction (e.g. ua-cam.com/video/F-9mpqAsg9E/v-deo.html). There is even a site (www.nestedtori.com/) named 'Nested tori' that is dedicated to visualisation of beautiful mathematical concepts. Of course, it has pictures of tori themselves (www.nestedtori.com/2012/10/welcome-to-nested-tori.html). So that you could watch nested tori while watching nested tori :)
Thanks. I have many biological applications. Will look at these youtubs. If you are interested in these applications email me and I will share them.
Hi., what kind of software is been used for the visualisations?
Hi! For the computations and visualisations power of OpenGL (GLSL) was used.
sorry i didnt ment that :-). wich software like paraview for example did yoy use ? thx
I didn't use any third party software. Solver of the Navier-Stokes equations was written by myself. Using the capabilities of the C++ and OpenGL (GLSL) I implemented algorithm from the article referenced in the description to the video.
Wow. That's fantastic, actually.
Thanks!!!
