thalaKonego

thalaKonego(x1, y1, x2, y2, x3, y3, x4, y4)

thalaKonego(x1, y1, x2, y2, x3, y3, x4, y4) gives a smooth curve that passes through all four points, in order. That is what separates it from thalaBezier, whose control points only pull at the line without touching it.

The name comes from the river. Konega is the word used when a river bends: “e konega kwa bokone botlhaba” — it curves to the north-east. It is the Setswana word for a curve.

What the end points do can be changed. Under seeloSaKonego('ends', AKARETSA) — the default — the curve passes through all four. Under PEELOTHOKO, the first and last points only steer, and are not drawn.

⚠ With both the stroke and the fill turned off, nothing happens at all — as with thalaBezier.
