  Run code

      import * as scrawl from '../source/scrawl.js'

  #### Scene setup

  Convenience labels - to save some typing

      const artefact = scrawl.library.artefact,
        stack = artefact.mystack,
        pin = artefact.pin,
        front = artefact.frontface,
        back = artefact.backface,
        top = artefact.topface,
        bottom = artefact.bottomface,
        left = artefact.leftface,
        right = artefact.rightface;

      const faces = scrawl.makeGroup({
          name: "faces"
      }).addArtefacts(left, right, top, bottom, front, back);

      stack.set({
          perspectiveX: "50%",
          perspectiveY: "50%",
          perspectiveZ: 1200
      });

      pin.set({
          order: 1,
          width: 0,
          height: 0,
          start: ["center", "center"],
          lockTo: "start",

- §

  To spin the cube we only need to rotate this element

  - canvases pivot to the cube element for position/rotation

          delta: {
              pitch: 0.4,
              yaw: 0.8,
              roll: 0.2
          }
      });

- §

  Give our canvases some common values, via their Group

      faces.setArtefacts({

- §

  Make sure the canvases get processed after the pin

  - so that they pick up changes to its positioning

          order: 2,

          trackHere: "local",

- §

  Common dimensions; common start/handle values

          width: 300,
          height: 300,
          baseMatchesCanvasDimensions: true,
          start: ["center", "center"],
          handle: ["center", "center"],

- §

  Offset each canvas from the pin

          offsetZ: 150,

- §

  Set each canvas to pivot to the pin

          lockTo: "pivot",
          pivot: pin,

- §

  Automatically add the pin’s rotation values to each canvas’s initial rotation value (set below)

          addPivotRotation: true,

- §

  Styling common to all the canvas elements

          css: {
              backfaceVisibility: "hidden"
          }
      });

- §

  Give each canvas its initial rotation

      right.set({
          yaw: 90
      });
      top.set({
          pitch: 90
      });
      back.set({
          pitch: 180
      });
      left.set({
          yaw: 270
      });
      bottom.set({
          pitch: 270
      });

- §

  Build some gradients to color the canvases

      scrawl.makeGradient({

          name: "red-gradient",
          endX: "100%",
          endY: "100%",
          colors: [
              [0, "#fff"],
              [499, "#f00"],
              [999, "#000"]
          ],
          colorSpace: 'OKLAB',

      }).clone({

          name: "green-gradient",
          colors: [
              [0, "#fff"],
              [499, "#0f0"],
              [999, "#000"]
          ]

      }).clone({

          name: "blue-gradient",
          colors: [
              [0, "#fff"],
              [499, "#00f"],
              [999, "#000"]
          ]

      }).clone({

          name: "yellow-gradient",
          colors: [
              [0, "#fff"],
              [499, "#ff0"],
              [999, "#000"]
          ]

      }).clone({

          name: "magenta-gradient",
          colors: [
              [0, "#fff"],
              [499, "#f0f"],
              [999, "#000"]
          ]

      }).clone({

          name: "cyan-gradient",
          colors: [
              [0, "#fff"],
              [499, "#0ff"],
              [999, "#000"]
          ]
      });

          name: "topface-block",
          group: top.base.name,
          dimensions: ["100%", "100%"],
          start: ["center", "center"],
          handle: ["center", "center"],
          fillStyle: "red-gradient"
