# 3D-Surface between 2 lines.

조회 수: 10(최근 30일)
Hi all,
Previously with one of the Mathwork community users' (darova) suggestion we created 3D surfaces on the sphere.
Here I have 3 surfaces the one of which (green) is below the other 2 surfaces.
Now, I aim to fill the gap between the top (red) and bottom (green) surfaces by creating an additional surface (i.e. an oblique surface (a slightly tilted surface)).
To make it clearer, in the output image of the attached code one can see 2 lines between the top (red) and bottom (green) surfaces.
I aim to create a surface between those 2 lines in order to close the gap.
I've tried several ways, and also a triangulation method, however, was not successfull.
Could you please make a suggestion on this.
I appreciate the time you spend.
Regards

xf = [xl2(1) xl2(5) xl1(4) xl1(5)];
yf = [yl2(1) yl2(5) yl1(4) yl1(5)];

I have a layman approach for this (The dumb method)
get co-ordinates by cursor
export them to workspace
save it in a variable
Now access all the co-ords
apos = [cursor_info.Position];
hold on,fill3(apos(1:3:end),apos(2:3:end),apos(3:3:end),'r','EdgeColor','none')

Hi Mehmed,
I will check this method, actually at the same time I want to generate triangular meshes on the surface.
However, if that won't work your suggested approach will be the solution.
Regards
Mehmet
