( fluid simulation library ) diewald_fluid

in Library and Tool Development • 2 years ago




hi,

new fluid-simulation library available here:

project page (reference + download): processing library - fluid simulation




- this library is made for simulating fluids in realtime
- the simulation can be done in two ways:
 a) on the CPU
 b) on the GPU, which is about 10 to 20 times faster than on the CPU
 the simulation happens on several shaders, that are loaded internally by 
 the processing library GLGraphics.jar by andres colubri 
 (http://glgraphics.sourceforge.net , or here http://codeanticode.wordpress.com/) 
 so you need to install GLGraphics.jar too, if you want to instantiate 
 the GPU fluid.
 
 
--------------------------------------------------------------------------------
online example: 
(it shows just the CPU simulation, ... GPU-simulation doesnt work within an applet)
http://www.openprocessing.org/visuals/?visualID=31335

--------------------------------------------------------------------------------
ZIP_CONTENT:
1) processing examples
2) reference
3) source-code
4) library: diewald_fluid.jar
 

--------------------------------------------------------------------------------
FEATURES:
- fluid-solver for 2d-simulation (maybe 3d will follow)
- GPU / CPU solver
- interaction with obstacles



--------------------------------------------------------------------------------
some update to improve GPU-performance even more, may be uploaded the next view days.

Great work, thanks! The performance is quite amazing, on my macbook pro with a relatively modest video card (geforce 320M) I get 30+ for all the GPU-based examples!

Video here (btw, I made using Syphon :-) )

Hi there,

I have another question concerning the obstacles in this library.
From my Kinect data I extract an object defined by vertexes (a human shape, see http://www.screenr.com/DUEs).

I found out how to "move around" block objects in the sketch, but of course I need the human shaped object. :)

Is there a class I can use to make the complex object respond to the fluid? Or another way to do this?

Cheers,

Jelmer

as i can see in your video, you visualized the blobs already.
now you can use that as a mask for the fluid-obstacles...meaning, the pixels (x/y-coordinates), that are part of the blob (contour and blobregion) can be used to make obstacles for the fluid.
the actuall coordinates of course depend on the resolution of the fluid, ...so you need the scaling factor, defined by the fluidgrid-resolution and the kinect-resolution.

hello

I´ve testing in my new laptop with ati 6470M and everything is blue :(

the colors in GPU mode is now working properly.

Somebody can test?

thanks
