returns vertex/facet list for a mechanical spring

Description

the spring consist of a base plate and a top plate and m helixes that are mounted between base plate and top plate

Syntax

[VL,FL,sx,sy,sz]=VLFLspring([r,h,n,m,dx,dy,l])

Input Parameter

r: Radius of the spring center; default is 5
h: Height of the spring (0-max); default is 50
n: number of full turns; default is h/r
m: number of springs integrated; default is 3
dx: width of the spring cable; default is 2
dy: height of the spring cable; default is dx
l: height of the base and top plate; default is dy

Output Parameter

VL: Vertex list of the spring
FL: Facet list of the spring
sx: Radius in x-direction
sy: Radius in y-direction
sz: Size in z--direction

Examples
