Render an image of the scene data
sceneShowImage(scene,dataType,gam)
The rendering can be either of photons or energy values. This is called
from the sceneWindow, so that axes are in that window. If you call this
from the command line, a new figure is displayed.
Examples:
sceneShowImage(scene,'photons')
sceneShowImage(scene,'energy')
sceneShowImage(scene,'luminance')
