Class Trail

Records the position and attitude history of a Mesh allowing the Mesh to be drawn in multiple historical configurations.

This class is refererce counted because it maintains a reference to a Mesh. You should call the release method when the trail is no longer required.

// The trail is constructed, at any time, on an existing mesh.
const trail = new EIGHT.Trail(mesh)

// Configure the Trail object, or use the defaults.
trail.config.enabled = true
trail.config.interval = 30
trail.config.retain = 5

// Take a snapshot of the ball position and attitude, usually each animation frame.
trail.snapshot()

// Draw the trail during the animation frame.
trail.draw(ambients)

// Release the trail when no longer required, usually in the window.onunload function.
trail.release()
