CNC Mandalas

Post by ArtF »

Hi All:

https://www.youtube.com/watch?v=8sSxO-Vss9c

I posted a video of some code Im working on for making laser mandala's. I like the look of such art, but
they look very tough or time consuming to invent. I have no time for that , but somehow I have time to program code
to do it for me. :). This code shows a few random generations of the main (top) patterns the program is suggesting.
The end output would include the insides of polygons being morphed on each deeper layer showing reliefs of the various
layers as it goes deeper. Im hoping to make the search space for such patterns to be in the millions of possibilities.
Many are similar of course, but surprisingly different and aesthetically pleasing ones pop up frequently so far.

I thought you might like to see a quick run of mashing the generate button.

Has any one cut such things in the past on their lasers or tables?

I've been v-carving a number of chip carving patterns lately. From the video they look like they're suitable for v-carving. VCarve really wants its closed vectors, by any chance are these shapes closed paths?

All are closed paths, as well as being their own closed paths, I mean if they share an dedge, that edge is included in each polygon.

yes. but without having your coding talent, only the hardway (especially duplicating shared edges -- for v bit tool path) ... perhaps soon having the benefit of your coding talent maybe using gearotic...

By Request, here are the first two tests on wood of the mandala output.
One is single level, the other multiple level, each took about 10- 20 seconds to burn.

Yeah, that's usually the part people complain about when trying to find such drawings. CNC needs that edge not to be shared typically
so that all polygons are individuals by themselves. Im almost done to a point where I can put out a preliminary release, but for that the
output will be either G Code in multiple layers (one layer per file ), GCode of all layers to be cut as one layer ( for texturing ), and finally
a grey scale output photo for laser engraving in 3d. Ill do a video of all three items being cut as well.
