Hello all , I have a conical section which is hollow and having variable radius and height . how to get all points inside the cone so that I can make it filled cone . I used this code -
r1=input('enter radius');
r=r1:-0.5:0;
[xc,yc,zc] = cylinder(r);
h=input('enter ht');
zc=zc*h;
figure(1)
surf(xc,yc,zc,'Facecolor','w');
grid on

There are an infinite number of points inside a cone.
To make a 3D object "filled", normally you just use opaque faces to draw it.

Hi Dr. Walter Roberson, can i consider your code as a point cloud of the cone.
