Round Raster 2 experimental (python script)

trandoductin · **Posted:** Sat May 14, 2016 5:39 pm **(#11)**

I call this one Round Border Raster Experiment.
Warning this script takes a really long time to render on larger selected areas, like enough time to go have a coffee and come back to.
sample selection 1

script renders this

sample selection 2

script renders this

selected shape blurred and bump mapped

it'll be availabe under Python-Fu/Round Border Raster Experiment...

This one is even slower and even more experimental.
selection

what script renders

blurred and bump mapped.

I particularly like the result of the lop-sided donut shape.
This is a different version of the script in the above post.

You can get those same kind of results just simply using a round gradient with the blend tool set to [shaped (angular)] and it doesn't take a whole lot of time.

If you could get something where the fill is lets say black on the outside and white on the inside, then that would be something new. The Path blend script is the only way I've seen that something like that can be done.

Black on the outside and white on the inside? doesn't invert do that? I am confused.

I mean anything with a hole in it. If you could do your slope type of thing, only from the inside to the outside of a donut. It is possible... anything is possible...
It's not possible though unless it's done manually.

i think that's probably easier manually.
I could probably do one shape with a hole in it but not a shape with 2 or more holes or many shapes with multiple holes.
It's probably easier right now to use lighten only and cut out the holes manually.

Just for a laugh, I tried using your height/depth map as a height_field image in POVRay (after inverting, POVRay treats white as the highest point)

Hi There,

I was just trying the script on a square and got the look of ceramic tiles. Such tiles have been used on the walls of our house. I had no plan to design them in gimp with this script.
