View Full Version : Water following curve

10-07-2004, 04:33 PM
I know I've seen talk on how to do water flowing through pipes before, but I'm can't seem to come up with the proper tool. This is more of an animated illustration rather than realistic, so I'm not thinking particles or hypervoxels, more of a solid semi-transparent object.

I have a series of pipes, and a subdivided cylinder object for the water
There is also a curve that runs through the center of the pipes.

In Layout I have the camera following the curve, but I can't seem remember how to get an object to deform along it.

You need to morph the water in modeler to follow the pipes trajectory. Then in Layout you morph the straight one to the deformed one.
You could also animate the water by giving a velocity to its texture in the lenght axis while on the straight water object. The morphed one will have the texture follow its path accordingly. And you can also make the water move down the pipes by applying a moving b/w gradient in transparency or clip map, also applied to the straight one, as the morphed and visible water will inherit that texturing lenghtwise.

Hope itīs clear

Use Curve Constraint on the tube... But, this will only get it to conform to it.

The old sliding bones trick could do it: http://www.md-arts.com/ Go to the tutes page and look for Slug Tutorial.

Something like this?

Something like this?


That would be it! I pressed forward using rail extrude and had it make UV's for me and did the animation using surfaces,

but what technique was uesd for that anim?

Thanks to all!

Mines done with actual displacements (normal displacement). :)

Here's one i did some time ago. At the bottom you can download the scene files. :)

does the camera follow the water inside looking at the water coming, or does it follow the tube above?

In my animation the pipe is cut in half with the camera a few feet outside looking at the pipe.

you can see the first (very) rough animation here
