I want to connect points on my plot, how can I do it?

I made a plot of point. I want to connect them and make a surface (volume if possible) as one solution and for the second solution I want to connect them with lines. How Can I do that? The code is here

clear all, close all, clc;

H=1700 %Visina osobe u mm
dSG=0.129*H % Duzina ramenog dijela od torza do ramenog zgloba
dH=0.185*H % Duzina nadlaktice
dF=0.146*H % Duzina podlaktice

%PRORACUN POZICIJE TOCKE WR ZA NAJNIZE VRIJEDNOSTI RANGE-A
for fiEf=-90:20:60; % rotacija oko x ramenog zgloba - RANGE je od -10 do 170 stupnjeva
    for fiA=-10:20:170
        for fiR=-60:20:90
            for fiF=-60:20:170

COSEF=cosd(fiEf)
SINEF=sind(fiEf)
COSA=cosd(fiA)
SINA=sind(fiA)
COSR=cosd(fiR)
SINR=sind(fiR)
COSF=cosd(fiF)
SINF=sind(fiF)

%rF=[0 dF 0]'

%Ref*rF
%rF=(0,dF,0)'
EF1=0
EF2=COSEF*dF
EF3=SINEF*dF
EF=[EF1 EF2 EF3]
%plot3(rWm(:,1),rWM(:,1),rW0(:,1));

%Rr*Ra*Rf*rH
%rH=(0,0,-dH)'
RES1=(COSF*SINA+COSA*SINF*SINR)*(-dH)
RES2=COSR*SINF*dH
RES3=(COSA*COSF-SINA*SINF*SINR)*(-dH)

RES=[RES1 RES2 RES3]

%rSG
rSG= [-dSG 0 0]

%rW=rSG+Rr*Ra*Rf*rF+Ref*rEF
rW=rSG+RES+EF

plot3(rW(1),rW(2),rW(3),'--k');
hold on;
grid on;
            end
        end
    end
end

I suggest that you first collect all points in an array. Start your code with the commands:

i = 1;

In the innermost loop, skip the plot commands i and instead insert:

 rW(i,:)=rSG+RES+EF;
 i = i+1;

You now have collected all your points in the array rW. The command:

plot3(rW(:,1),rW(:,2),rW(:,3));grid on

will plot lines between your points. Probably not in the way you would like, but I cannot help that.

I do not speak your language, so I have no idea what you are trying to do here, but your points do not lie on a well-defined surface, so a surface plot will not make any sense. If you use only one value of fiEf, then all the points seem to lie on the surface of a sphere. For other values, the sphere is shifted somewhat.

For plotting a surface, once you figure out what you really want to plot, try this link, or this.
