evenly lit from all sides. Ambient lights are almost always used in combination with other types of lights. Lights need to be included in the <b>draw()</b>
|
|
to remain persistent in a looping program. Placing them in the <b>setup()</b> of a looping program will cause them to only have an effect the first time through the loop.

The effect of the parameters is determined by the current color mode.</p></td>
