Help needed modelling raindrops
Im trying to model raindrops hitting water.
Can anyone suggest how I can have simultaneous wave generators,rather that the central based tool in Gimp.I need to be able to adjust the parameters in the same way as the distortion tool allows...any help would be appreciated.
Thanks in advance.

Win vista (for now)

RE: Help needed modelling raindrops
Many thanks Ofnuts :-) very well explained,and very helpful indeed.
Im particularly interested in the reflective feedback patterns,and im sure this is the way to go about it.
Thanks again,for this; and for your time taken to explain it to me.
Cheers - Steve

RE: Help needed modelling raindrops
Many thanks for your clear description :-) what i am looking to do though,is animate the ripples...using the image created, as a frame..
The technique i really need to develop,is to allow the ripples to feedback,and create an interference pattern..
this would involve a control to adjust the individual wavelength,and frequency of each droplet,as per the wave tool (which only allows the center as a point source)

Perhaps,i can create individual frames using the conventional wave tool,then align the layers in an offset way,and using the grain merge you described get the results i require...hmmm...sounds feasable...will test an let you know..
You have really been a great help,and i am most grateful :-)

Just wanted to update you Ofnuts,thanks to your excellent info,and smart tips :-) I have found a succesful way to create the effect i was looking for - using these and combined techniques from them..This will keep me busy for months now :-)

I don't suppose you'd care to share this revolutionary new information with the rest of the world, would you, please? It would seem I was on a quest today for this very same procedure, & I just had to join the forum just to ask -- only days after you first joined and posted. Weird.

btw thanks ofnuts for getting me started on the bumpmap. I got lost at "Set the layer mode of all the ripple layers created to "grain merge" ; I've seen it before but I'm one of those who can't find a simple "burger, fries and a coke" anywhere on a McDonald's menu.

RE: Help needed modelling raindrops
ofnuts, thanks. Of course, it still took me 10 minutes of poking around everywhere to find it, over by floating > refreshing > carbonated > non-fruit > non-dairy. Managed to count the number of times I found the word Layer or a form of it, was up to 8 when I gave up. Wasn't until I saw the Lock button when I figured it out.

Still looking for a tut on animated rain hitting a puddle. Found 1 useful, the rest are about rain in the air.
I suppose I'm looking for what might be called multi-seeding ripplets effect, if anyone can link or post a vid tutorial, please do so.

Thanks again,

RE: Help needed modelling raindrops
I dont know if I can explain easily to be honest..using the image software is just a small part of the results..I wouldn't say its 'revolutionary' ,maybe thats humour :-) Regards - Steve
