Scenes and light

Tutorials on creating and describing scene spectral radiance, the first stage of the ISETCam pipeline. See Scene Radiance for the conceptual page and Tutorials for the full topic index.

• t_sceneIntroduction (source) How to create, inspect, and modify a scene object using the *Create/*Get/*Set/*Plot/*Window pattern, including how dependent properties such as sample spacing update automatically when you change field of view or distance.

• t_sceneRGB2Radiance (source) Converts an ordinary RGB image into an estimate of scene spectral radiance.

• t_sceneSurfaceModels (source) Uses linear models to approximate surface reflectances for scene rendering.

For real measured scene datasets (hyperspectral, multispectral, and HDR), see Spectral Scene Data. For an adaptable longer example that reads multispectral scene files, see Examples.
