wave forms

[jdgrahamwaldorf]

Does anyone know of a wave form generator that will output a dxf file? I want to model a "stone thrown into the water" effect.

Thanks

I have cobbled up a series of eps files to do this, called the Ripple Toolkit. Is this the effect you were looking for ?

It needs to have a weave option. Just sayin'.

Ha! There are so many ways to change the ripples that it quickly gets messy. This is where I think it is easier to doing it in math, and import the vectors or 3D toolpaths.

If you are OK with doing a bit of Lua coding, there is a program called "Make_CSV_Toolpaths.lua" included in the 'CSV' gadget package that will create 3D toolpaths which can be imported into Aspire4 or VCP7 via the CSV gadget. There are some 'factory' routines in the file that you can modify to do just about anything you want, but rings and drops are included 3D shapes...


Cheers!

That goes without saying CarveOne !

The 6 ripples that I came up with are in the attached eps file. To use them

1) Import the file into an Aspire layer, and select the one wave you want to work with. I think it looks best with all wavelets having the same number of crests, same crest spacing, but different diameters.
2) Copy and paste that one onto a working layer.
3) Stretch it to make the distance between crests what you want. Don't worry about the height yet.
4) Make a bunch of circles of different diameters, and scatter them around the layer.
5) Use the extrude tool with the circle as the rail and the wave as the cross-section to make individual components. Target a height of ~1/8" to 1/4" each. Make each with the Add mode.
6) Move the components around to overlap as much as you want.
7) You may want to add a zero plane.
8) Now do a bake of all components
9) Toolpath it with a 1/8" to 1/4" ballnose, and look at the previews. You can undo the bake and move them around if you like, then rebake

The ripple waves can also be used as frames using other shapes as rails ...
Sorry C1, no weaves yet ...
Cheers!

Looks good Paul. That will be a useful tool.

Lua... That's a Hawaiian beach party, right?

I found your CSV gadget pack, and downloaded it. I'm still running VCP 6.5, so when I upgrade to VCP 7, I'll check it out. When I upgrade to Aspire, I'll throw a Luau!

Thanks!

Paul,

Thank you for the information. I believe that your toolkit will work for my project.

Glad to hear that John. Feel free to ask if something isn't clear. Tweaking the ripples is also a possibility (but not in the next week or so). The shapes are a bit arbitrary, but I think reasonable.
Cheers!
