Plotting between a point and a frame

Hi, i have a parametric equation to obtain a frame in 3D and i can plot it just fine.

I have an arbitrary point in space and if i draw a line from this point to the middle of the frame, whether it be a rectangle or circle, it is perpendicular to the surface enclosed by the frame.

As the point, frame and distance between them known, how can i create a surface between the frame and the point? It is like if i am drawing lines from all the points in the frame to the single point away

Not excatly sure if I've understood your question, but here's my attempt at interpreting it:

n = 50;
t = linspace(0,2*pi,n);
hold on
plot(cos(t),sin(t))
line([zeros(1,n);cos(t)],[zeros(1,n);sin(t)],'Color','g')
plot(0,0,'.','MarkerSize',40)

I have a feeling this isn't what you are after - you may be after the fill function.
