Hello, I hope you had fun Christmas.
This is a small demo showing real-time snowflake growth using an animated alpha map. The animation frames are stored in a single image, 255 frames in a single color channel.
buttons 1 and 2 enables post-process effects (vignetting, noise, edge-blur, and a new and awesome lens distortion filter, made by Francois Tarlier, and slightly modified by me).
Up/Down - shrink/grow the snowflake
mouse wheel up/down - chromatic dispersion amount
7/4 - lens distortion coefficient
8/5 - cubic distortion amount
9/6 - image scaling amount
Edit: Maybe this thread should be in Game Demos section?
