Adds a directional light.
Adds a directional light. Directional light comes from one direction: it is stronger when hitting a surface squarely, and weaker if it hits at a gentle angle. After hitting a surface, directional light scatters in all directions. 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
v3 parameters are interpreted as either
HSB values, depending on the current color mode. The
nz parameters specify the direction the light is facing. For example, setting
ny to -1 will cause the geometry to be lit from below (since the light would be facing directly upward).
