Generate and Crop Fibers

Generate random fibers inside a box, then crops the fibers into smaller box

Generate randomly oriented fibers inside a box, then crops the fibers into smaller box. Example file is provided.

1-function Fiber=Generate_Fiber(x,y,z,L,N): Generate fibers inside a box

2-function Plot_Fiber(x,y,z,Fiber): Plot fibers

3-function Fiber2=Crop_Fiber(xb,yb,zb,Fiber): Crops the fibers into smaller box

where:

x=[x1 x2]: x boundaries of the box

y=[y1 y2]: y boundaries of the box

z=[z1 z2]: z boundaries of the box

L: Length of fibers

N: Number of fibers

Fiber: (N,6) matrix of fiber coordinates with (:,1), (:,2) and (:,3) are x,y, and z coordinates of one end and (:,4),(:,5) and (:,6) are x,y, and z coordinates of the other end.

xb=[xb1 xb2]: x boundaries of the smaller box

yb=[yb1 yb2]: y boundaries of the smaller box

zb=[zb1 zb2]: z boundaries of the smaller box

Fiber2: (N,6) matrix of cropped fiber coordinates with (:,1), (:,2) and (:,3) are x,y, and z coordinates of one end and (:,4),(:,5) and (:,6) are x,y, and z coordinates of the other end.
