Method: lightFalloff()

lightFalloff(
   constant, 
   linear, 
   quadratic): void;

Configure distance attenuation used by point lights.

Uses the p5-style formula: 1 / (constant + d * linear + d * d * quadratic). Negative inputs are clamped to 0. If all inputs resolve to 0, the falloff resets to (1, 0, 0).

Parameters

Parameter	Type	Description
constant	number	Constant attenuation term
linear	number	Linear attenuation term
quadratic	number	Quadratic attenuation term

Returns

void
