Blue Noise Particles

I’ve released a plugin generates a random arrangement of particles with a blue noise distribution. This is also known as Poisson Disk Sampling.

Shows blue noise distributed particles in comparison to other options

This distribution of particles guarantees no two particles are very near each other. It’s often considered a higher quality particle arrangement than Blender’s default uniform sampling. It’s particularly useful for organic arrangements, and randomly arranging meshes without collisions.

Celtic Knots

I’ve created a Blender plugin generates 3d beziers curves in elaborate “celtic” style knotwork, based off of a framework mesh. Tested with Blender 2.68a. It’s available on github.

Celtic Knots are a intricate decorative design found in Celtic and other cultures mosaics and manuscripts. The knots often include elaborate variations and unusual angles that the plugin does not attempt to create, so touching up the resulting path in blender may be necessary for some designs.

Refer to the tutorial for some instructions on how to use the plugin, and the gallery for some examples of what is possible.

Tileset Roundup

Following my development of Resynth Tileset, I’ve been doing some thinking on the nature of tilesets, and the possible ways to auto tile them – that is, to paint tiles as is with a brush and letting the computer do the tile selection. Let’s review a few possible ways of doing so.

Just to be clear, I’m only interested at the moment in square, non-rotatable tiles. Rotation is another discussion, but excludes the more interesting tilesets. Adding alternative tiles is also not considered, though it is pretty easy to add in.

Sprite Choppa

I saw a poster on TIGSource talk about manually cutting up sprite sheets, so I’ve dusted off a project from 2007 to solve it. Just load up a sprite sheet, select the background color, and export the results into a directory. It’s got a few extra features useful for what I originally wanted it for, too.

Just remember, this is from the archive, so way crappier than the stuff I do nowadays. I’ve barely touched it, except to brush off a few GUI bugs and delete menu options that don’t do anything.
But it does the job.
