How to plot a dome in MATLAB w/ different radii?
I need to plot a dome (or half sphere) that have different radii. I was told how to plot the shpere on a previous question:
[x,y,z] = sphere; %# Makes a 21-by-21 point sphere
x = x(11:end,:); %# Keep top 11 x points
y = y(11:end,:); %# Keep top 11 y points
z = z(11:end,:); %# Keep top 11 z points
r = 3; %# A radius value
surf(r.*x,r.*y,r.*z); %# Plot the surface
a开发者_Go百科xis equal; %# Make the scaling on the x, y, and z axes equal
Does anyone know how to plot a dome (aka half sphere) in MATLAB...or anyother programming language?
But I need the height of the x, y, and z components to all be different.
How do I change the code?
Let's call the radius in x, y, and z rx
, ry
, and rz
, respectively.
Then you call the function like this
[x,y,z] = sphere; %# Makes a 21-by-21 point unit sphere
x = x(11:end,:); %# Keep top 11 x points
y = y(11:end,:); %# Keep top 11 y points
z = z(11:end,:); %# Keep top 11 z points
rx = 3;ry = 4;rz = 9; %# Define rx, ry, rz
surf(rx*x,ry*y,rz*z); %# Plot the surface, multiplying unit coordinates with radii
axis equal; %# Make the scaling on the x, y, and z axes equal
