Light3D

Create a point light

Makes it a spotlight: the angle in radians from its forward out to the edge of its cone, so the beam is twice this across; 0 for a light that shines every way

How much of the cone is its fading edge: 0 a hard edge, .2 by default, the outer fifth, 1 fading all the way from the middle of the beam

Shine from far away, from its position toward the origin, instead of out from its position with a falloff; DirectionalLight3D sets it

The light's lens flare, undefined for none: addFlare makes it, or set a LensFlare3D of your own, and destroying the flare takes it away

• The flare is the light's: it is attached to the light as its child, so it stays through a scene change when the light does, and is destroyed with the light or when another takes its place

A gel: a picture the light shines through, like a stained glass window or the leaves of a tree, cast along its cone in its colors, upright as the light looks out, the whole texture of a TileInfo; only the spotlight that casts the shadows has one, with render3D.shadows on and it as render3D.shadowLight, and only on what takes its shadows: an object with receiveShadow off is lit without the gel; its alpha is not read, see through panes are dark

Size of a soft hazy glow drawn over the light, like a lamp at night, 0 for none; it is added onto what is behind it, and what is in front of the light hides it

How fast the glow fades from its middle: 1 by default, .5 a wide haze, 2 a tight bright core

Brightness, multiplies the color, above 1 is brighter than white

Distance where the light fades to nothing

Give the light a lens flare, made with the arguments of LensFlare3D, in place of the one it had

Destroy the light, and its flare with it

Draw the glow, a quad facing the camera with a soft round glow on it, pulled toward the camera by half its size so a lamp at the light does not cut into it, but never past the camera
