View Full Version : Pouring Liquid

10-02-2006, 05:49 PM
What is the best approach - or dare I say easiest - for pouring liquid out of a glass. And let me be clear by saying I really only need a semi-realistic simulation - lighting and rendering is of little to zero importance.

Thanks gang

I think you can achieve a pouring effect if you use HVs and set a really high velocity stretch. The easiest way would probably be to use either blender's fluid dynamics or Realflow.

I heard blender has good fluid dynamics...

You can do it with some creative use of endomorphs and maybe some particles and HVs as well. :)

I came to the same conclusion myself after reading a bunch of threads.

I guess LW can't do it all ;)

Thx for the quick response.

It's a pity really. HV's would be a pretty neat solution for this kind of stuff.

It's the actual particle generation that can't handle the water in a glass scenario. It's a pity Newtek haven't added some kind of particle 'buffer' distance to the particle calculations. I know there's basic collisions in there but they don't take into account full 3D space collisions for particle size. Even if there was a tick box for 'Full Collision / Size /Space Calculations' it might take a lot longer to calculate but could get us all out of some scrapes.

Some experimentation in Blender by some Spinquad members. Pretty impressive.

Also check out LW's own HVDeform - for an example, see http://www.newtek.com/forums/showthread.php?t=56358&highlight=waterpool.

Yes very frustrating because I need the most simple simulation - I'll have to find yet another work around - man I hate 3d sometimes ;)

If you want simple, I'd recommend RealFlow. Easy to use, terrific results; pricey though... You can search on this forum for examples, but let me point you to a simple one I did recently - see http://www.newtek.com/forums/showthread.php?p=435159.

Did this following Larrys tutes on displacements.. (http://www.3dthunder.com/pouring.html)

is this tutorial available to download- cant find it myself?

The tutes are available at Kurv studios (http://www.kurvstudios.com/lightwave/displacements_II.php) and Larrys site (http://www.3dtrainingonline.com/displacements2.htm). Generally Larry doesn't sell via download, but if you e-mail him he might be able to sort something out..

Thanks Rich! :)

I do allow downloads especially for those overseas. Drop me an email - [email protected]
