Show examples of built-in scenes
ISET includes many built-in scenes that are used for testing the properties of optics and sensors. This script shows how to create those scenes.
Many of built-in scenes can be created using parameters that are set when you call the sceneCreate function. This script illustrates how to set thses parameters. You can learn how to create these scenes by using
doc('sceneCreate')
