Receiver2D, Receiver3D

model.result().dataset().create(<dtag>,"Receiver2D");

model.result().dataset().create(<dtag>,"Receiver3D");

model.result().dataset(<dtag>).set(property, <value>);

model.result().dataset().create(<dtag>,"Receiver2D") and model.result().dataset().create(<dtag>,"Receiver3D") create 2D and 3D receiver data sets, respectively. Use these data sets to collect the data necessary to visualize the impulse response for a Ray Acoustics simulation (of room acoustics, for example), using an Impulse Response plot. The Impulse Response plot uses the data from a Receiver data set as input.

The following properties are available:
