dat-gui-defaults v1.1.0

dat-gui-defaults

A useful wrapper of dat.GUI with defaults support. The provided DatGuiDefaults class makes it easy to write a demo app that requires default configuration handling.

Setup

Installation

$ npm install dat-gui-defaults

Usage

1) First, subclass DatGuiDefaults and implement initGui(gui, data, params). For example, here we create DemoGui class.

class DemoGui extends DatGuiDefaults {
    // override
    initGui(gui, data, params) {
        //-------- begin sample --------
        let controller = gui.add(params, 'wireframe').name('Wireframe');
        controller.onChange((value) => {
            data.wireframe = value;
        });
        controller = gui.add(params, 'reset').name("Restore Defaults");
        controller.onChange((value) => {
            this.applyDefaults();         // API to restore defaults for dat.GUI
            Object.assign(data, params);  // reflect the change in the app
        });
        //-------- end sample --------
    }
}

2) Use the custom class with an application data object.

const data = {                // app data
    wireframe: true,
};

const dg = new DemoGui(data); // instantiate with data
dg.setDefaults({              // defaults passed to dat.GUI
    wireframe: data.wireframe,
    reset: () => {},
});

API

• new DatGuiDefaults(data)

  data (Object): app data object to be manipulated.

• datGuiDefaults.setDefaults(params)

  params (Object): the params object for dat.GUI.

  Set the default parameters.

• datGuiDefaults.applyDefaults()

  Restore the default parameters for dat.GUI.

• datGuiDefaults.gui

  The underlying dat.GUI object can be accessed this way.
