nx_arousal_body.nx

nx_arousal_body.nx -- arousal progression ON THE BODY, not on a chart. Sphere-traces the sovereign SDF humanoid (nx_sdfrender's 18-ellipsoid form, feminine morph from nx_body_figure) as an orthographic FRONT view, maps every surface hit to an anatomical site by its world position, and shades it with the real Beer-Lambert skin optics at that site's perfusion. Emits a FILMSTRIP: the same body at N times, so flush PROPAGATION is visible as it spreads. Bands and ticks are an abstraction of the physiology. This is the physiology on a body. ★Front is -z in this rig (breasts and face both sit at -z), so the camera looks along +z. ★SITE MAP is by world (x,y) against the rig's own part centres: head/neck y>980, arms |x|>380, legs y<-150, breast y>700, sub-mammary y>560, torso y>200, else pelvic/genital. usage: nx_arousal_body <out.png> <sex0m1f> <drive_permil> <melanin_permil> [propensity] [track] license_tier: ORIGINAL expect_exit: 0
