The Concepts of Tracking

Tracks in slush


Tracking Concept“: (as used here)  Any aspect of reading the tracks and trail of any being or object through time, and across any surface that will hold a track (touch your finger to clean glass, or a dark iPad screen, then tilt into the light).  These include; body and substrate movements, definitions, methods, how to find and read both tracks and trails, the tracks of specific species, the influences of all the layers involved, signs, substrate types, and track structures.

Initial Idea:  Solve the first problem, the opaque foot.

The Goal:  Create a scene with ground, sand objects, and a 3-D translucent foot.  Animate the foot for one un-hurried walking step on level ground.  Set the scene up so the foot creates a track by interacting with the sand objects in a way as close to “real-world” as possible, with the laws of physics applied.  Create a video clip from this animation.

In this clip animation controls the movement of the foot, while Rigid Body physics controls the sand objects’ interaction with the ground, each other, and the foot … and so the formation of the track.
