PropertyMixer class

Buffered scene graph property that allows weighted accumulation; used internally.

Buffer with size valueSize * 4.

This has the layout: incoming | accu0 | accu1 | orig

Interpolators can use .buffer as their .result and the data then goes to incoming. accu0 and accu1 are used frame-interleaved for the cumulative result and are compared to detect changes. orig stores the original state of the property.

Constructors

PropertyMixer.new(PropertyBinding binding, String typeName, int valueSize)

Methods

accumulate(int accuIndex, double weight) → void
Accumulate data in accuIndex incoming region into accu[i]. If weight is 0 this does nothing.
accumulateAdditive(double weight) → void
Accumulate data in the incoming region into 'add'.
apply(dynamic accuIndex) → void
Apply the state of buffer accu[i] to the binding when accus differ.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
restoreOriginalState() → void
Apply the state previously taken via 'saveOriginalState' to the binding.
saveOriginalState() → void
Remember the state of the bound property and copy it to both accus.
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
