Compute skater states, pack definition, pack shapes and engagement zone shapes. Used in Track-Viz project.
The computed track is centered at (0, 0). The coordinate system follows the SVG or screen coordinate system with x value from left to right and y values from top to bottom.
This package is using the metric system.
Uses lodash and three.js. Tested with three.js ^0.115.0 and with lodash ^4.17.15. Will probably run on different versions as well. Three.js is used everywhere because of Vector2 for vector computations.
2D and 3D rendering examples can be found in the examples folder.
