Here is a pic from my first VJ outing, for Dronetronics, in Taipei, back in December.

Lars from Dronetronics got in contact 2 hours before the gig, to see if I had anything for a gig at a studio not far away.   I …

I've been pretty busy so far doing laying the groundwork for my audiovisual project. I've got the architecture worked out, so ones this stage 0 is complete I can start coding it.

Uploaded, 2 videos using shoebot... 4 others waiting to be uploaded.

Todays daily graphic I'm getting familiar with grids (in shoebot), Vector maths from the planar library .. this started from the grid example from shoebot / nodebox.

Shoebot Code Below the fold

``` {: .brush:python} """ Grid of arrows that point towards the mouse pointer.

Uses planar library for Vec2, angles. """

Based on grid- …

Not sure how practical it is, but will try and upload a new graphic everyday .. to start with will probably be quite basic :) Here is the first, some moving granular thingies..

Shoebot code:

``` {: .brush:python} import random from math import sin, cos

size(800, 800) colours=ximport("colors")

def draw …

Playing with python, zeromq and Gtk, I made this code to send graphics commands to several windows.

Commands are sent over a zeromq PUB socket, the windows recieve them using zeromq SUB.

Only a few commands are wrapped as it's a proof of concept.

I'll clean it up and abstract …

Perlin noise is pretty cool, you can use it to generate realistic looking clouds or mountains.

Here's a bot for shoebot I made a while back that uses perlin noise to generate some nice circles.

You'll need shoebot and the lib "noise" installed into your environment for it to work …

Here's a little creative coding I did with processingjs a while back. Move the mouse to move the skulls.

OK, part 3 - now for something fun - extending parts 1 + 2 into a simple particle system.

Particles, generally means - a lot of things moving around (the particles) and a way to generate them, an "emitter"

Here we're going to take the code from the previous two parts and add a …

In my last post we made an arrow move around the screen, in this post we'll look to extend things so it's easy to make many things move around the screen.

This will make the code a little more complex, but as usual it makes things simpler later on.

Note …

Here's a little shoebot bot to experiment with natural movement.

This uses polar coordinates to decide the direction and velocity of an arrow on the screen.

Polar coordinates mean we can give an object a sense of 'forward', 'back', 'left' and 'right'

The code below works on the current version …
