geometry.transport

Carry a vector along as the unit direction from turns onto the unit direction onto: rotated about their common perpendicular by the angle between them, and made square to onto again. Frames carried this way along a curve stay free of twist.

Inputs

• vector (Vec3). The Vec3 carried.
• from (Vec3). The unit direction before the turn.
• onto (Vec3). The unit direction after the turn.

Outputs

• vector (Vec3). The carried unit vector, square to onto.

local carried = g.geometry.transport({ vector = vector.create(1, 0, 0), from = vector.create(0, 1, 0), onto = vector.create(0, 0, 1) })
