Hey i had binary map of aphere's net The map (180x360 matrix for az,el) cover 24% of the sphere and Represents Camera field of view. I want plot the sphere, only where the binary map are true. And where ita false to make no sphere (or sphere with transparency 100%, II add pic of the camera field of view (before make it binary map)

Ran in:
What about plot3?
[x,y,z] = sphere(20);
[az,el] = meshgrid(200:5:250,0:5:20);
[x1,y1,z1] = sph2cart(az*pi/180,el*pi/180,1);
plot3(x1,y1,z1,'.r')
surface(x,y,z,'facecolor','none','edgecolor',[1 1 1]/2)
axis equal
