 \n\u003e ***Tip**: Save the settings you don't want to lose as a preset before experimenting.*\n\n### Features\n- Generate as many pendulums as your computer can handle\n- Single Pendulum support (by setting 2nd bob's Mass to zero)\n- Configure the *Simulation Speed*, *Damping*, *Gravity* and *Mode* of each system\n- Manage the *Mass*, *Angle*, *Velocity*, *Radius* and *Color* of each bob\n- Customize the *Length*, *Width* and *Color* of rods and trails!\n\n- Customizable Canvas with:\n  - Pause button\n  - Pan and zoom\n  - Fullscreen mode\n  - Capture the moment with *Right-Click -\u003e Save image as...*\n\n### Tips \u0026 Tricks\n- Change all colors of a DP at once using the square on the left of the dropdown-header \n- Set some opacity to the Canvas background color for cool phasing effect. \n  \u003e *It has some side-effects - you can set it back to opaque color to get rid of them.*\n- The presets use JSON, so you can create cool stuff (that would be really hard to do by hand) with basic programming, e.g. random colors or gradual lengths.\n- You can use optimized single pendulum math by setting all *Mass*, *Bob radius*, *Rod width* and *Trail width* of Part 2 to zero.\n\n### Made with:\n- \u003ca href=\"https://vuejs.org/\" target=\"_blank\"\u003e\u003cstrong style=\"color: #42b883\"\u003eVue 3\u003c/strong\u003e\u003c/a\u003e reactivity\n- \u003ca href=\"https://p5js.org/\" target=\"_blank\"\u003e\u003cstrong style=\"color: #ed225d\"\u003ep5.js\u003c/strong\u003e\u003c/a\u003e rendering\n- \u003ca href=\"https://getbootstrap.com/\" target=\"_blank\"\u003e\u003cstrong style=\"color: #7734fb\"\u003eBootstrap 5\u003c/strong\u003e\u003c/a\u003e styles\n- \u003ca href=\"https://seballot.github.io/spectrum/\" target=\"_blank\"\u003e\u003cstrong style=\"color: #e83072\"\u003eSpectrum\u003c/strong\u003e\u003c/a\u003e color pickers\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fitzterra%2Fdplab","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fitzterra%2Fdplab","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fitzterra%2Fdplab/lists"}
