Treasure Island

San Francisco from Treasure Island

A timelapse from Treasure Island in the San Francisco Bay.

The first half of the video is looking west from Treasure Island and pans along the San Francisco waterfront. The second half was shot east towards Oakland and includes a storm sweeping in from the north.

High Roller Timelapse

Lassen Star Trails

Star trails from the Manzanita Lake campground at Lassen Volcanic National Park

A timelapse two ways shot from the Manzanita Lake campground at Lassen Volcanic National Park (the second time I've visited and the second time that Bumpass Hell has been closed). First a regular 4K timelapse looking up from the campsite:

The second version is the same footage in HD where each frame is the cumulative maximum pixel value of all the frames up to the current frame (so it builds in star trails as the video runs):

Draw the rest of the Hummingbird

Generation three thousand of a genetic algorithm learning to draw a hummingbird

A genetic algorithm learns to draw a hummingbird:

The video is an animation of three thousand generations of evolution. It starts with a random mix of line segments which are then mutated by adding or removing lines and by changing the start, end and color of existing lines. Each generation has 32 individuals. The best individual is mutated to create the next generation.

For this implementation the best or fittest individual is the one with the least error on a pixel by pixel comparison to a stock art drawing of a hummingbird. Because I care more about the shape than completely filling in the drawing an error outside the figure is penalized three times more than a gap inside the figure.

Color is mutated each generation but not selected for, so it's just changing randomly.
