| Description |
|
Adds a spot 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 affect of the v1, v2, and v3 parameters is determined by the current color mode. The x, y, and z parameters specify the position of the light and nx, ny, nz specify the direction or light. The angle parameter affects angle of the spotlight cone. |
