void setup() { size(100, 100, P3D); background(0); noStroke(); } void draw() { // Include lights() at the beginning // of draw() to keep them persistent lights(); translate(20, 50, 0); sphere(30); translate(60, 0, 0); sphere(30); } |
| Description | Sets the default ambient light, directional light, falloff, and specular values. The defaults are ambientLight(128, 128, 128) and directionalLight(128, 128, 128, 0, 0, -1), lightFalloff(1, 0, 0), and lightSpecular(0, 0, 0). 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. 设置默认的环境光源、方向灯、衰减和镜面值。缺省值为 ambientLight (128、128、128) 和光源 (128、128、128、0、0、-1)、lightFalloff (1、0、0) 和 lightSpecular (0、0、0)。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。 |
