A couple of experiments with flocking. In the second example I tried to get the particles to combine when they got close but still be able to diverge if they wanted. :
A network of particles that attract to an average center of all of the particles. If there is a blob in the camera frame they are attracted to the highest point.:
Experiments with particles in a vector field. The red cricle is the average point of all the particles. All particles have a force drawing them towards this point as well as forces drawing apart and downward.:
A network of particles that each have a value associated with an FFT frequency range. They are drawn to the center but react to their specified FFT range:
A network of particles that make and break connections depending on the proximity. Particles must be within 100 pixels of each other to make a connection:
Tribute to John Whitney:
This is a rather bad example of what I had hoped to create for a tribute to John Whitney. His animation style has many subtlties that I could not capture. I had several visions for what I had hoped to achieve, but they did not work out as I wanted. This is the best result.
Visual Sound:
I wanted the visuals to be generated by sound, so I found an example I could steal from and I hacked some stuff together. I have never done any sound visualizers before, so excuse me for reinventing the graphic equalizer.
animation experiment:
I could have edited these in Final Cut, but I liked the way that this looked as I scrolled through iPhoto. I thought that it added dimension to my animation.
fastest non moving speed:
The block moves 0.01 or one-tenth of an inch per frame, at 60 frames per second.
That means that the block moves one pixel every 1.4 seconds. It is noticable when it snaps a full pixel, but its slow.
My screen resolution is 128 pixels per inch so I used that as my standard of measurement.
179.2 seconds per inch = 2.98 minutes per inch.
63360 inches = 1 mile.
Fastest non-moving speed = 0.0003 mph or three-tenthousands of a mile per hour. download zipped xCode file here
fastest still perceptible speed:
The block moves 32 pixels per frame, at 60 frames per second.
It take the block four frames to move one inch.
The block moves 1,920 pixels per second, at 128 pixels per inch resolution = 15 inches per second.
Fastest continuous speed in MPH = 0.8. download zipped xCode file here
three recordings of three different scenes which have interesting motion:
I tried to find random and organic motions. These will be hard to track, but I like how unpredictable the can be.
