Golang LengthSqr Examples

Example #1

File: circleShape.go Project: marimo-lab/chipmunk

func (circle *CircleShape) Moment(mass float32) vect.Float {
	return (vect.Float(mass) * (0.5 * (circle.Radius * circle.Radius))) + vect.LengthSqr(circle.Position)
}

Example #2

File: segmentShape.go Project: marimo-lab/chipmunk

func (segment *SegmentShape) Moment(mass float32) vect.Float {

	offset := vect.Mult(vect.Add(segment.A, segment.B), 0.5)

	return vect.Float(mass) * (vect.DistSqr(segment.B, segment.A)/12.0 + vect.LengthSqr(offset))
}
