Question Filling a Volume

Could someone tell me how to show a glass filling with water.
the facet and water source can be invisible, i merely need to show a container go from empty to full.
I'm assuming i would need to use an emitter and maybe add collision properties to it so as to confine the contents to the container... but i may be way off here as i am a bit new to this.
thanks in advance.

i really dont know how to do it .but there is a program called realflow that does awesome water animations and effects.

heres the link check out some of the videos in the gallery there to see what it can do

Thank you very much for the reply. i have heard of Real flow and found it was quite expensive and probably overkill for what i need. you see, i don't really need any special effects, meaning no waves or ripples or such, i merely need to show a hollow box fill up with material, fluid etc. What i am trying to do is simulate a plastic injection mold being filled with plastic. in the past i merely utilized transparency, going from 100% to 0%, sort of dissolving the part into the scene. but this isn't really accurate, especially up close. Rather, i need to show this process in better detail with the material starting at one side of the cavity, or void, and filling to the other side.
thanks again.

Well, you could try using morphs to show the fluid filling the void. I think this might achieve the effect you need. Take a look at the attached files - they may give some pointers.

thanks for the tip, i have never used the Morph tools, this is slick.
it seems you need to define the morph (the before & after) in modeler and simply activate the morph within the animation over a specific length of time, frames etc.
Nice!
To expand on myissue a bit, suppose you needed to fill and oddball shaped part, let's say the letter N, from one end to the other. Is it possible to do a morph that would start at the lower left leg of the letter, travel up, then diagonally down & to the right that then fianlly up to complete the letter?
you see, i am trying to fill a part that is a word, my company name, NYPROMOLD INC., and would like to show it starting to fill from the beginning of the first letter to the end of the last letter.
i guess i should have made this clear up front but figured once i had the technique i could apply it to anything. Not sure if Morphing can do this for me... thoughts?

thanks again, I really appreciate the tip and your efforts.

Well, you could do it using MorphMixer, but it would be a total shag to do it. You see morphs are simply a linear displacement of points, so you would have to combine several morphs to achieve the effect you require.

Other ways you could look at doing this would be:

(1) Realflow - expensive (both in cash outlay and render times), but will do the trick like no other method.

(2) Worley's Acid plugin (part of the Polk pack) - this allows you to change a surface's texture and bump based on an effector (expensive in cash outlay, but a great pack if you have a use for it - 33 plugs in total)

(3) Surface Effectors from Premdesign - similar to Acid.

(4) Morphs - as already discussed.

(5) Hypervoxels - use the dynamics tools in Lightwave to fill the volume with particles. Apply Hypervoxels to these to surface. Will be a total pig to set up, but should do the trick.
