Another growth test
Things are getting more interesting with the growth script. The resource map used by the lifeforms is now drained as they use up the energy available. This energy doesn’t grow back, and so puts a limit on the time a fixed world can sustain life. The nodes have another trick up their sleeve though –…

Post industrial rehab
So over a year on from leaving the world of computer games megacorporations and big budget movie special effects, it’s maybe time to be a bit less terse than usual and compare and contrast against life in the shadowy world of arts, academia and free software. There are fairly obvious benefits of leaving the 9.00-6.30…

Resource maps
This is the same growth algorithm as the video I posted on Tuesday, but with a non-uniform resource – painted with a texture map. There is a bug meaning that failed connections aren’t deleted, but I like the way that islands are colonised. Posting here I just noticed the similarity with the hapstar graphs…

Tectonics
Some animation tests. Inspiration from geological and growth processes, and with any luck, eventually their interaction.

Mesh collision volumes in fluxus
Thanks to learning a bit more about ODE you can now, finally specify a mesh as a collision volume to the physics system. The meshes have to be indexed triangle list polygons, so I’ve also added (poly-build-triangulated) for making a triangle list polygon primitive from any other polyprim. You can then use (poly-convert-to-indexed) to make…

Hapstar 0.5
Hapstar is released, and now has it’s own website. Here’s a screenshot of an example haplotype network of human and neanderthal DNA sequences.

Plant Eyes v11 movie
I’m trying to start the year catching up with documentation – here’s a new video of the latest version of plant eyes: I’ve also added a page for it with some more information here.

Particle filters
A particle filter is a technique used in computer vision to estimate the state of a system, given noisy data from fallible sensors. The underlying idea is called a hidden markov model, and looks something like this: The assumption is that any state of the system is dependant on it’s previous state (and thus all…

Impasto
For no particular reason, I thought I’d have a go at writing a raytracer 100% in scheme (it actually started as a port of this which I wrote ages ago). I run it in the mzscheme interpreter for development and then compile it using stalin to render stuff. I’m hoping maybe it can serve as…
