🌌 Omnipresent Space: Huygens-Fresnel Wave Field (2D)

Top-down heat map of the superposition of waves from many coherent sources, following Huygens' principle that every point of a wavefront is a secondary source. Change the spatial dimension, wavelength and absorption, drag the sources and probe, and read interference gain and energy density live.
