mirror mode or symmetry mode

Postby tunjin » Tue Jun 16, 2009 5:18 am

hello

i have good idea for new features inkscape:

new tool "mirror mode" or "symmetry mode"

first i turn ON "symmetry mode" and i start to draw use with :tool_pencil: or :tool_calligraphic: or :tool_pen: or :tool_spiral: or :tool_star: or :tool_ellipse: or :tool_rectangle: ..

i do draw for unferstand for you
this is symmetry with 1 originale and 3 mirror (clone) draw, total is 4 draw:
Image

what do you think about new tool "mirror or symmetry mode"

because it's very very important..when i begin to draw with symmetry mode there is 3 point (clone draw-mirror (y,x,-y,-x) with real time draw mirror
Image
as blender there is mirror when begin to modeler...it's potential features...
i love inkscape all time!!

There is such a feature in the development version already, although I'm not sure if it will be included in 0.47. It's under Path effects.

hello

i did found an example for you!!!!
got to site but you do fullscreen for FIREFOX ok?: ***spam***

tu go to active "symmetry:" (and you try to draw it's super COOOOOOL!!!! :shock: :shock: :shock: :shock: :shock:

supercool interessant:"symmetry points" till to 100!!!

I WANT THE INKSCAPE SAME FEATURES SYMMETRY ALSO FROM 2 -100 POINTS OF SYMMETRY!! IT'S CAN FOR INKSCAPE FUTURE?
LET ME KNOW PLEASE!

I VOTE THIS COOL SYMMETRY FOR INKSCAPEEEEE

Hi, do you know where or if this is located in 0.47pre? The mirror feature is one of the main reasons I still use Alchemy

Lots of path effects are disabled in the dev version because they haven't been tested enough, Mirror symmetry is one of those. There is a way to enable them if you compile inkscape by yourself, do you want the instructions (I'm on linux, don't know about other OSes)?

I tried it now and it seems to be working ok on single objects, but not on groups.

Please! I'm on Ubuntu 9.04. Only just figured out how to compile 0.47pre2 so go easy on me :D

I'm also on ubuntu 9.04 :) Here is a post I made recently about compiling Inkscape, basically it's just executing some commands in terminal, one by one viewtopic.php?f=22&t=3518&p=16274#p16274
I create a special folder to hold the dev versions, it doesn't interfere with the official one, you'll have both at the same time.

To get the effects that are disabled by default you will need to edit a file in a text editor somewhere along the way, here is the shortened version of the post I made earlier with the extra step to get all of the effects:

Download the source snapshot from http://inkscape.modevia.com/svn-snap/?M=D
Open terminal
$ mkdir inkscapedev
$ cd inkscapedev/
$ tar jxvf [path to downloadeed file] example:tar jxvf /home/[username]/Download/inkscape-22***.tar.bz2
$ cd inkscape-22***

Now is the time to edit the file - it is called effect.cpp and it's located in inkscapedev/inkscape-22***/src/live_effects/effect.cpp

Open it with Text editor (gedit) and find the line that reads //#define LPE_ENABLE_TEST_EFFECTS, it will probably be the line #9, you need to delete the first two characters of that line (//) so that you end up with #define LPE_ENABLE_TEST_EFFECTS on that line.

Now you can continue with the commands in terminal.

$ ./autogen.sh
$ mkdir build
$ cd build
$ ../configure --prefix=`pwd`/../install
$ make install

Let me know how it goes :)

Sorry if I sound like a complete nubcake here, but isn't this pretty much the same as just copying and using the 'flip selection horiz/vert' options?

It is, in a way. It's a lot easier to i mirrored path if it's automatically drawn. Take a look at this picture as an example. In that program mirror is applied to each path automatically. In a way it's like an environment or canvas effect, rather than just a path effect

You can also use flipped clones ;) But with mirror effect you can set the orientation of the mirror axis. Maybe there are even more advantages, not sure atm.

Mirror drawing would be a useful feature in Inkscape. I recently read this post about mirroring with clones, it might be useful for you:
http://simarilius.wordpress.com/2006/08 ... -the-wall/

Here is a Turkish friend, made a video about it: http://www.youtube.com/watch?v=di6cZIxPsC8

He also made some templates for mirroring to use them in working, you can download them: http://ozbekanil.googlepages.com/inkscape-aynalama.7z

Yes! I've been wanting something like this, too.

What I want, specifically, is a symmetry clean-up tool. You try something
with the bezier too that is roughly symmetrical, then you select the
symmetry effect. You check whether you want to currently correct side
to be left, right, top or bottom, and then it mirrors that to the other side.

Hey folks,

I discovered a useful way to do mirrored editing: group any object, create a clone of it, then do a horiz or ver mirror on the clone and reposition it beside the cloned object. Then enter the original group and start editing inside of that group and things will show up mirrored beside it. That's how I created the design for my "Hallowed Confluence" featured on the :


Star Tetrahedron
Image

and Spikey model
Image

of the Cosmic SpaceCraft Lanterns collection (see more here http://cosmic-spacecrafts.blogspot.com).

Still, I do wish that there was a way to do mirrored editing of a single path, but I find it's a tricky feature to even define nevermind implementation. I guess vaguely what I'm looking for is some way to define a mirror relationship between 2 nodes of a path.

Cheers to symmetry,

Welcome playful_geometer!

I don't know how I missed the original message, because I love symmetry, and would love to draw in such a proposed "mirror mode". Something similar to this is possible with cloned layers. Here is a simple file that I picked up from this topic: viewtopic.php?f=6&t=3300 by tomh. I haven't actually figured out how to clone a layer, but tomh did, and it's fun to play with!

You don't see things AS you draw them. But as soon as whatever you're drawing is complete, it shows in the clones. So for example, start to draw a line with the Pen tool, in the "pie wedge" that lies between 9 and 10:30 (if the pie were a clock face). You can only see it there. But as soon as you double-click to end the line, then it's shown in the cloned layer. Or if you move an item -- you can only see it move as you drag it, in the "edit layer". But as soon as you release the mouse, the object moves in all the other segments. Here I'll also include an image I made using the above file as a template. (sorry it's so big)

Layers are just groups in Inkscape, so the techniques are really just doing the same thing!

It is the same way I make corner flourishes.
