Today I have been working on a motion tracker in AS3 that works on tracking the edges of the user this is so that I can create a snow fall effect that allows snow to settle around the user. I saw something similar to this done in AS2 when I was back at university by Grant Skinner. I’m trying to reproduce this in AS3, this is a project for a group of freelancers I work with known as The Interactivists. Basically we are creating something similar to what G Skinner used as an installation for a shop window.
So onto the code, I have started by bringing in a camera feed and applying filters to it until I have the edges highlighted in white the theory next is to basically dynamically make snowflakes which land on the generated surfaces and stay there until they are moved or disturbed.
