A new angle on flash frequency

In a previous post, Vlaya and I showed how the flash frequency can lead to many nice effects.

A question of angles

After a long reflection, we realized that for many reasons the best way to describe the flashes is not by their frequency, but instead by the absolute angular position of the Phyllo when each flash occurs.

Therefore, each image description will contain the colors frames and a pre-computed absolute angle (which may be procedurally computed or included in a stored animation).

These absolute angular positions are not to be confused with the relative angular rotation of the motor between two consecutive flashes.… Read more

Pretty Animations

These past few days I’ve been working on the animation generator. Here’s a result:

I wrote a generator in C (which will later be the code used on the main board) which has a generate_frame function which will generate the next frame of a procedural animation. The generate_frame function can be called an arbitrary amount of times.

The code can export the frame to a file, which is then read by my animation simulator script I wrote for blender.

The simulator takes a few secondes to read the frames (5 secondes for a 500 frames animation for instance), and can then display the animation in real time (same as in the gif)

The simulator can also render high quality realistic animations as the one you can see in our project presentation , but even a small animation will take a day of rendering

Here’s all the concepts / techniques I have been working on right now (most of them are already implemented) which the generator uses:

Virtual Petals

The virtual petals are the petals you appear to be seeing go down (age) on our phyllo animations.… Read more
