Inventing On Principle Applied to Shader Editing

Recently I have been playing around with GLSL Sanbox (github), a what-you-see-is-what-you-get shader editor that runs in any WebGL capable browser (such as Firefox, Chrome and Safari). It gives you a transparent editor pane in the foreground and the resulting compiled fragment shader rendered behind it. Code is recompiled dynamically as the code changes. The […]

Show Your True Colours

This last week saw the release of fairly significant update to Gource – replacing the out dated, 3DFX-era rendering code, with something a bit more modern, utilizing more recent OpenGL features like GLSL pixel shaders and VBOs. A lot of the improvements are under the hood, but the first thing you’ll probably notice is the […]

New Zealand Open Source Awards

I discovered today that Gource is a finalist in the Contributor category for the NZOSA awards. Exciting stuff! A full list of nominations is here. I’m currently taking a working holiday to make some progress on a short film presentation of Gource for the Onward!. Update: here’s the video presented at Onward!: Craig Anslow presented […]

Life is Strange

Here is my tribute to a fascinating new fractal I talked about in an earlier post, the Mandelbulb. (Youtube: http://www.youtube.com/watch?v=W3x4uJJqs_w) The music in the video is ‘Life is strange (trance remix)’ by darkangell. I recorded the scenes using my work in progress Mandelbulb Viewer/Fly through builder application (which is on my github, if you’re curious). […]

New Logstalgia Released

I’ve just released a new version of Logstalgia, my website access log visualization that looks a bit like Pong if only it had been created by Jeff Minter. Logstalgia is also referred to as ApachePong (referring to both the Apache Web Server and Pong) which is a much better name, but also covered by multiple […]

Linux.Conf.Au 2010

Last week I attended Linux Conf Australia, the annual conference for all things Open Source down under, this year held in Wellington, New Zealand, the city where I live. I was very lucky to get the opportunity to organize some of the displays at the conference. An application developed for the conference displayed information such […]

Gource in Bloom

My earlier experiment with Bloom (I am tempted to call it Gourceian Blur) has lead to a new effect/feature in Gource. (Youtube: http://www.youtube.com/watch?v=NjUuAuBcoqs) The bloom effect is achieved by blending radial gradients with each other additively. You can do a high quality version by drawing a perfect radial gradient with a Shader, but in Gource […]

Gource: Software Version Control Visualization

Gource (the name is a play on Source and Gorse) is a new visualization for software projects (and perhaps over things? I’ll try to stay focused here) which I released a couple months ago after spending the best part of this year working on it in my spare time and in between projects at work. […]
