Constructor Details

#initialize(world, parent, pin_tra, group = nil) ⇒ PointToPoint

Create a PointToPoint joint.

Parameters:

  • world (MSPhysics::World)
  • parent (MSPhysics::Body, nil)
  • pin_tra (Geom::Transformation, Array<Numeric>) —

    Pin transformation in global space. Matrix origin is interpreted as the pin position. Matrix Z-axis is interpreted as the pin direction.

  • group (Sketchup::Group, Sketchup::ComponentInstance, nil) (defaults to: nil)

Since:

  • 1.0.0
