Lighting Switch Global Lighting On/Off Switch
Lighting Switch Global lighting on/off switch
By default lighting is ON , and a plot implying lighting will use the current attributes. If lighting is turned OFF all formerly lit elements will be drawn at the full colour intensity with no shading effects.
Turning the switch on/off does not change stored lighting or shading attributes in any way.
These two examples show how a hemisphere, half
SI
contoured and half
SH
shaded, responds to the
lighting switch. Note how turning lighting off destroys any perception
of shape or depth.
(The effect on the right could also be achieved with lighting ON by setting the Ambient light to 100% and having no point light sources active.)
