Light Intensity by Distance Calculator
Applies inverse square law to estimate intensity falloff as subject moves away from source.
Law: I2 = I1 * (D1² / D2²). Ideal to estimate losses on virtual set.
Inverse Square Law in 3D Lighting
Intensity falloff determines perceived volume and depth. Applying I2 = I1 * (D1² / D2²) helps match lights across scenes and simulate physical realism in renders.
