True it's neater. My fairy is unrecognizable with Gimpressionist.

Provide me a link and I'll render your fairy in either glass orbs or BBs (ball bearings). lol

You can see I'm still on this binge. ;)

Alas, my fairy isn't yet done. I just didn't have any other pics on my machine at the time. Thanx.

Yeah, I tried and found that out. I like your version better than what I came up with.

So far in my effort to write a script-fu POVray scene file generator, I've got to this:

At least you got Script-fu to write povray output Kevin. Cool stuff. :)

Hopefully tomorrow I'll try some different shapes.

I would like to test your Script-fu too Kevin, if you don't mind that is. As for the original plugin, I did manually edit it and played with a few shapes. Anyway, what would be cool is incerting disks, but I can't get it to give you true circles for whatever reason. What I really would like is a dynamically sizing disk (spheres would be cool too) based on a criteria such as value, color, or saturation; a Perculator killer if you will. Not sure how to code such a Script-fu though. :)

You're very welcome to try it out, but be warned, it is only a proof-of-concept at the moment, so it doesn't do anything helpful, like point the camera at the middle of the image.

Thinking ahead I can see the user interface becoming enormously complicated, so a move to python and using PyGTK or TkInter to build the GUI is probably in order. Any volunteers?? ;)

I don't know this Perculator of which you speak, but changing object sizes (or other aspects) is straightforward BUT efficient packing afterwards is more than I could cope with.

As for "true circles", I suspect you're not thinking 3-dimensionally - the edges of the "image" are further away from the camera, so you get perspective distortion. You can also get distortion with camera settings that conflict with the aspect ratio of the image you try to render (640x480 etc).

I'm not at a machine with POVray installed, but I suspect that if you change the camera type to orthographic, you'll get what you're looking for: http://www.povray.org/documentation/view/3.6.1/245/

Kevin

p.s. As it's a work in progress, I haven't set the menu location to something friendly - it locates itself at Script-Fu>>Kevin>>POVray Samples...

Edit: Removed the version of the script from this post - it's been superseded.

Just tried it Kevin; had to figure out where the pov file is stored but I did. Cool. The result below is because I've not played with parameters yet. Thanks for sharing Kevin. :)

I've just remembered - this reminds me of Gimpressionist's Marble Madness filter.

just discovered this Marble Madness filter and the Ballpark which seems similar. thanks for that. :clap

it's adorable...I guess there's no way to get those to line up the balls?

You can make squared and unpacked renders in GIMPressionist, but not packed. See attached result. :)

Packed just means reduced gaps Cecilia; ofsetting orbs such as the texture that I created (a while back; posted it at my Deviant (yes; ssp. lol)). Click on the image for it's Deviant (and yes, it's seamless). :)

You can't use the texture above in GIMPressionist Cecilia. For the GIMPresionist example, I used the built in ball.ppm brush. :)

ok, I obviously have to work on my (lack) of understanding of GIMPressionist
