Ich hab jetzt einen Weg gefunden damit es optisch besser aussieht. Er verbindet jetzt nur die Punkte falsch. Wie löse ich das? Siehe auch bilder im Anhang.

Code:

x=pos(:,1);
y=pos(:,2);
z=pos(:,3);
tx= -2.5:0.1:2.5;
ty= -2.5:0.1:2.5;
[XI,YI]=meshgrid(tx,ty);
ZI=griddata(x,y,z,XI,YI,'cubic');
II=isnan(ZI);
ZI(II)=0;
surf(XI,YI,ZI,'FaceColor','red','EdgeColor','none');

camlight right;
lighting phong;
set(gca,'CameraPosition',[2 2 1.5]);
grid on
xlabel({'X';''})
ylabel({'Y';''})
zlabel({'Z';''})
stem3(pos(1:250,1),pos(1:250,2),pos(1:250,3),'o','linestyle','none');
