Package net.paulhertz.pixelaudio.curves

Class GestureTransformState

java.lang.Object
net.paulhertz.pixelaudio.curves.GestureTransformState
public class GestureTransformState extends Object
Stores optional affine-transform state for a gesture/curve. See net.paulhertz.pixelaudio.example.Bagatelle or Bagatelle skatch in Processing examples. Transform order: 1) flip/scale about pivot 2) rotate about pivot 3) translate

  • Field Details

    • enabled

      public boolean enabled

    • translateX

      public float translateX
      Translation in display units (pixels).

    • translateY

      public float translateY

    • rotation

      public float rotation
      Rotation in radians.

    • scaleX

      public float scaleX
      Scale factors before rotation.

    • scaleY

      public float scaleY

    • flipHorizontal

      public boolean flipHorizontal
      Mirror left/right around pivot (negates x scale).

    • flipVertical

      public boolean flipVertical
      Mirror up/down around pivot (negates y scale).

    • pivot

      public processing.core.PVector pivot
      Optional pivot for scale/flip/rotation. If null, utilities may use the bounds center of restPoints.

    • restPoints

      public ArrayList<processing.core.PVector> restPoints
      Optional rest pose to avoid cumulative drift during animation. Use to recalculate derived points accurately.
