Description

Adds a point light. Lights need to be included in the draw() to remain persistent in a looping program. Placing them in the setup() of a looping program will cause them to only have an effect the first time through the loop. The v1, v2, and v3 parameters are interpreted as either RGB or HSB values, depending on the current color mode. The x, y, and z parameters set the position of the light.

添加点光源。需要在绘图 () 中包括光源, 以便在循环程序中保持持久性。将它们放在循环程序的设置 () 中将导致它们在第一次循环时产生效果。根据当前颜色模式, v1、v2 和 v3 参数被解释为 RGB 或 HSB 值。x、y 和 z 参数设置光源的位置。
