Charge Risk Javascript Sandbox

Current Project

6. Toward a bike Jump with Planck.js

• Basic bike
• Multi-fixture pickup truck.
• Wheelset attached to a boxy, wagon-like body.
• Two wheels, joined together, on same downhill course
• Single spoked wheel rolling and flying down a hillside.

5. Side journey to learn Planck.js

• Starter for new projects   ⦁   Planck2   ⦁   Planck3   ⦁   Planck4 / 4a
• Planck5   /   5a   /   5b
• Wind blowing on grains

4. Toward a Bike Jump with Matter.js

• Experiments in gravity and motion, part 2--prototype bike jump.
• A Rolling Spoked Wheel
• Working toward a bike jump!
• Bike jump with an image of a real bike
• Initial experiments with physics engine Matter.js
• Sort of a bike jump with physics engine Matter.js
• Better jump and a rolling wheel
• Car wheels on a gravel road
• Mountain bike (not sucessful)

3. Some Geological and Nature Applications

• 2D extensional tectonics with full-physics particles
• 1D Diffusion of complex topographic profiles
• 1D Diffusion of escarpment
• Improved river meandering
• Isostatic balancing of lithospheric columns
• Artificial landscapes with Perlin Noise (2D)     ⦁   3D version with flyover
• Mattias Müller's Euler flow simulation

2. Simple Motion and Forces with P5.js

• OOP: constructing a Class of moving boxcars
• Shiffman style physics with no real-world time or length.
• Simulation of balls falling through air and liquid
• Experiments in gravity and motion, real time and length
• Gravitational attraction between bodies     ⦁   N-Body Simulation (a la Shiffman)

1. Baby Steps

• Slightly embellished version of Khan Academy trivial animation example
• Basic statistics with Simple Statistics     ⦁  Basic graphs with Plotly.js
• My version of the Prisoner Riddle   ⦁  The Monty Hall Problem
• P5 random function number generators    ⦁  Basic file I/O
• Finding center of mass of 2D polygons
• Graphing a random walk
