Live Mirror Drawing

Postby enveloppe56 » Sat Sep 10, 2016 7:51 pm

I am looking a way to design mandala and snowflake in Inkscape. I need to draw a drawing, that will be repeating several times. I would like to fine a way to use a live mirror drawing, that's mean, drawing inside a shape and see the vector repeating in live automatically in the over shape. I find exactly a tool doing that for illustrator, an plugin called "MirrorMe", do you know if there is a way to have a similar result with inkscape ?
Thank you for your help :-)

The only way to do it "live" in Inkscape is to use clones. See parts 28 and 29 of my tutorial series: viewtopic.php?f=6&t=11981

The next version has a mirror path effect: http://wiki.inkscape.org/wiki/index.php ... r_Symmetry (with video)
And a kaleidoskope path effect: http://wiki.inkscape.org/wiki/index.php ... ate_copies (with 3 videos)

And Lazur has made a 'Snowflake generator' template, which makes it very easy to create snowflakes: https://openclipart.org/detail/206156/s ... -generator (already works in 0.91)

Just a note on the so called "mandala" designs (made manually).

Inkscape's rendering (and all other renderers for that matter) is producing a gap between objects touching i.e. repeated/cloned objects next to eachother in a circular array. Meaning, if you wish to repeat one segment, this rendering gap is visible.
Therefore I'd suggest overlaping the tiles.
How? First lay down paths that overlap and cover the right segments, then use them to clip the tiles and make these tiles exceed the clipping area.
Needless to say it works 100% ok if there is no transparency is involved in the parent tile.

Having said that, the mentioned snowflake generator doesn't use clipping and overlapping, and would produce messed up results if the objects inside the parent group have strokes/gradient fills added.
For an overlapped "snowflake generator" check this.

For nice examples on a basic circular array for clipping, look at this svg.


Also a related example.
(Although the filtering produces other rendering issues in 0.91's cairo, it works fine in chrome.)
