The 17 plane symmetry groups in Paint.Net?

[Joker54]

Hi,

I have recently taken interest in symmetry groups and symmetry operations.

(see http://en.wikipedia.org/wiki/Wallpaper_group)

 

Symmetry operations can be an amzing design tool.

I looked in the plugins database, but all I could find is a mirroring effect, not any glide operations, axis rotation operations and combinations thereoff.

I was wondering if it is possible to code a plugin with codelab that can take an object and perform symmetry opetrations on it, accoording to any chosen symmetry group (or allow the user to choose point of symmetry, define a unit cell, etc).

 

If it is possible, I would appriciate it if you refer to to a codelab tutorial - I am familiar with C programming (if "HEY, World" can be considered as familiar...)

 

Thanks.

Hello World!

BoltBait has some excellent codelab tutorials here:http://boltbait.com/pdn/CodeLab/help/tutorial.asp

I have thought about a plugin along these lines to help with tessalations - to explore Escherish/Islamic patterns, but decided it was far too difficult for me!
However I believe it would be possible and a great plugin to have.
Tiling and reflecting are relatively easy when rectangular but more complex symmetries could be a head-ache.

Good luck - maybe worth starting a thread in the Developers central section of the forum if you have a beta and need advice.

If it will help to get you started here is some codelab code for a little tiling/reflecting plugin that I abandoned ... the anti-aliasing when scaling down was getting too problematic.
Simply unzip the .cs file, open in codelab and build the .dll (then restart Pdn).
