Graphics Utilities

Particle Accelerator

Executive Summary: create image grids from movies -- suitable for making animated particles from videos of explosions or whatever.

You basically pick the grid width and height and the rendering scale and then click a button to create the grid and another button to save it out. More recent versions include support for setting in- and out- points and crossfading the animation to make it loop. That's all there is to it.

New Features in v1.0.1

This test animation obviously does not loop.

This is the same file processed using linear crossfading.

New Features in v0.3

New Features in v0.2

Executive Summary: it's a simple program for watermarking images.

Someone asked about watermarking software on a forum I frequent, and so I wrote this little app. Free for personal use (i.e. use by persons).

Waterboy has a dazzling array of features... well it kind of has one feature. It lets you watermark with text or a PNG image (presumably with an alpha channel), and you can pick where you want your watermark to appear. You can export as JPEG and set compression levels. That's it.


1.3: The cursor changes when pointing to the watermark (as if to indicate you can drag it around, which you can)

1.2: You can now reposition the watermark with your mouse (the offset is from the pinned position you choose)

1.1: Added support for exporting various file formats: PNG, PSD, TGA, BMP, etc.

Skybox Utility

Skybox Utility is a simple application for converting a short movie (comprising six images) into individual images for use as a skybox. Its default settings assume that you:

Skybox Utility 0.6, August 26 2008

Added Save Cross... option to save out the "tiles" image (which is useful if you want to use the skybox as a rendering backdrop in some 3d packages, such as Cheetah 3d.

Skybox Utility 0.5, August 25 2008

Added sample offset slider. This allows you to fine-tune the sample points that the utility uses to extra faces (don't touch it unless your faces don't extract correctly).

Skybox Utility 0.4, June 23 2008

Mostly cosmetic improvements.

New Features in v0.3

I fixed some minor bugs (most notably I misnamed two images on save) and added some CoreImage goodness.


Alphaville is a simple application for creating images with arbitrary alpha channels (why would you want to do this? Well it's useful for Unity development, and I can think of some other reasons).

Alphaville (despite its simplicity) has a slicker UI than the other utilities (it supports drag and drop). I plan to go back and update the others some time.

If you don't know what this all means, chances are you do not need this program.

The icon is based on posters for Jean-Luc Godard's cult film Alphaville which is a strange film indeed. The main character, Lemmie Caution, played by Eddie Constantine (that's his image, used without permission :-o ), is some kind of detective and the movie has nothing to do with computer graphics at all. It does, however, appear to have been a major influence on the role-playing game Paranoia.
