Two files, as a comparison. One with a cylinder (crashes here) and one without (renders ok).

I did dig up a blender cylinder from the web and that crashed as well.

edit: still have that one, give it a try.

rich2005, try this version (i've changed it so that i recognizes different types of faces' definitions)

an even more updated version of this plug-in: ->here<-

May try this one later trandoductin; looks cool for importing wireframes of Sculpture Generator output.

That is working with cylinders now.

I thought I would be a bit more ambitious and try some extruded text. Took some time to render but it got there.

However, I need to do some work on the orientation.



All good fun, thanks

looks better if you try it on black background because i draw it with gray shades fades to white where white is the closest edges and and dark gray are further edges.

I looked up Sculpture Generator and gave it a try. It exports to .stl file. So i used an converter (http://www.greentoken.de/onlineconv/).

I found that the .obj file converted had duplication of vertices and faces defined. So I changed the plug-in to find unique vertices and unique edges only.

With the below test/sample (from 12601 vertices down to 2099 unique vertices, from 12600 edges down to 6300 unique edges)
so it reduces the workload to call gimp_pencil so not as slow (still slow since there's a lot of edges to draw)



Here's the updated version of the plug-in that finds unique vertices and edges only.


Go ->here<- for later version (auto-scale version)

Oh great now you have me breaking out Sculpture Gen again.
Lyle will know what i mean.

Nice filter by the way.

break it out

Already have. Notice the change in the interface

My results with your filter.This took a very long time to process by the way on my Windows 8 64 bit machine.
Size of the OBJ file is 8 MB.



It is still drawing by the way. The size is already 2.2 gigs

I blame gimp_pencil for speed

I have added an auto-scale option.

It will calculate to fit the furthest point from the center of image (to take up 90% so leaving 5% at the closest edge to border, see sample image below where autoscale is selected)


Here's the auto-scale version of the plug-in

See next post for an ULTRA-fast version (access pixel data directly instead of calling gimp_pencil)

this latest version will run in seconds instead of minutes! (doesn't call gimp_pencil but manually draws lines/edges by accessing the pixel raw data)

another version that doesn't bother search for unique vertices/edges (it's actually faster to just draw them all than searching for them) that version is ->here<-

Yes that newest filter works much faster now. Thank you.
Same OBJ file and much smaller size results.

thanks for trying it out Rod!

Any time.

I found that by searching for unique vertices/edges it's actually slower than just drawing it with the fast version so this version
just simply draws so it's even faster.

Tried it out with a huge .obj file with 100000 triangles (buddha.obj) had to draw it on a really large canvas (6400x8000) then cropped.


otherwise if drawn on a small image, you'll get a sort of gray shading (with some holes)

Wow that draws really fast now. 37 seconds for Budda.obj file.

Trandoductin, Just letting you know the plugin works in Gimp 2.6.11 (win 7)
