points.sphere (procNode)

Points in or on a sphere, even by volume (or by area on its surface), each carrying N: the way straight out from the centre. Use it for bursts, explosions and puffs, where N becomes a velocity.

Draws on channels 0 to 2 of the emit scope: u is the height on the unit sphere, then the angle around it, then the radial share points.shell_radius turns into a radius.

Built from: rand.unit, points.shell_radius, core.points, math.*.

Inputs

• count (Float, default 256, at least 0). How many points. Each is drawn on its own, so raising this fills the same shape denser without moving the points already there.
• seed (Float, default 1). Which of the possible layouts this is; the same seed draws the same points on every run and platform.
• radius (Float, default 1). The sphere's radius.
• center (Vec3, default (0, 0, 0)). Where the shape stands.
• shell (Float, default 1, 0 to 1). How thick a skin of the shape the points fill, as a share of its radius: 1 fills it to the middle, 0 lays every point on its surface.

Outputs

• points (Points). count points carrying P, N (unit) and id.

local burst = g.points.sphere({ count = 500, radius = 0.2, shell = 0 })
