You can also try adjusting the above sliders:
Clicking on theicon next to the sliders will show or hide the visualization for that attribute's calculation.
This is a GPGPU based boids simulation that uses the WebGL 1.0 specification for good cross-browser support. The boids movement is based on this paper by Craig Reynolds, with the addition of touch interaction and some other minor tweaks for performance.
The image below this big box represents the gpu generated direction for every boid.
As such, it is very flashy since it is recalculating the direction every frame, to 32 bit precision.
That is why this box is so big.
It is to make sure that the big flashing image is not displayed when the page is first loaded. I have tried my best to reduce the flashyness of the image while still maintaining most of the raw output from the GPU.
