Sumagna Das (Jul 25 2020 at 16:48): Sumagna Das (Jul 25 2020 at 16:48):hey @Sean, i made a picture of pentagon(with black background and white foreground) using my graph plotter app
ebm.png
Sumagna Das (Jul 25 2020 at 16:48):its resolutions are 599x599
Thusal Ranawaka (Jul 25 2020 at 16:49):Nice
Sumagna Das (Jul 25 2020 at 16:49):after i converted the png to bw file(it gave a little warning which is normal), i made an ebm inside of mged using the command
in pentagon ebm f ebm.bw 599 599 20
Sumagna Das (Jul 25 2020 at 16:50):it came out like this on the graphic window
Sumagna Das (Jul 25 2020 at 16:51):
Sumagna Das (Jul 25 2020 at 16:51):(look at one of the sides of the pentagon)
Sumagna Das (Jul 25 2020 at 16:51):it is not like the other sides
Sumagna Das (Jul 25 2020 at 16:51):what happened here?

Sumagna Das (Jul 25 2020 at 18:41):the base of both the pentagons are weird
starseeker (Jul 25 2020 at 19:00):Might be one pixel thick? do they raytrace?
Sean (Jul 26 2020 at 01:48):@Sumagna Das that's just because those voxels are perfectly aligned horizontally with the axis, so the wireframe displays them more simply. The other sides are not axis-aligned, so you see the stair-stepping. That said, the real shape can be seen if you run a raytrace, like rt -s1111
Sean (Jul 26 2020 at 01:50):if you don't like that one side is clean like that, rotate the image slightly so that no edges are axis aligned. Increasing the resolution will also help a little bit (e.g., 4096x4096) if you rotate. Then you can raytrace with hypersampling or downsampling to smooth out the result.
