DolphinLightMetaballs

Centers stay within .35 of each half extent and radii within .235 of the minimum extent. Six blends can expand the union by at most 6*k/4=.30*min. Thus the entire field stays inside .885 of the supplied shape bounds. Its gradient has length <=1, so |field distance| is a safe marching bound.

Build bounded lighting experiments with geometry, visibility, transport, film, and GPU/CPU contracts.

external DolphinLightMetaballs(dolphinLightShape s,int index,float time,float ox,float oy,float oz,float dx,float dy,float dz,float maximum) returns dolphinLightHit

Status: source-declared

Supply oz as float.

float dx

Supply dx as float.

float dy

Supply dy as float.

float dz

Supply dz as float.

float maximum

Supply maximum as float.
