Spring Physics Simulation

This project is a 2D pixel simulation of spring connections between nodes using C++ and the olcPixelGameEngine. The original goal was to simulate rope, which was achieved by connecting many nodes closely together. Properties such as tension and stretching can be shown, furthermore, if a few nodes are connected it also simulates soft-body physics.

Features

• Physics

  • Spring physics based off equillebroium distance between nodes.
  • Force application such as gravity.
  • Toggle air resistance

• Interaction

  • Delect node to lock in position
  • Add to nodes and connect nodes together
  • Delete nodes

• Graphics

  • Nodes can be drawn as circles or not drawn
  • Springs drawn as lines
  • GUI to show details such as number of nodes, whether the user is in edit mode.
