generate sphere using two coordinates

Hallo, I want to plot a sphere with diameter of distance between the two coordinate points (x1,y1,z1) and (x2,y2,z2). and also adjust the colour settings. thanks for your help.

The euclidian distance between the two endpoints is the diameter, and the mean of the coordinates is the center point. After that it is standard creation of a sphere with known center and radius.

The method of creating the sphere is going to depend on what properties you want it to have. For example if you do standard lat/long banding then you need to decide where the poles are to be.

Hallo Walter Roberson, for some reasons its not working.

x = [-10 -25 -46]
y = [12  12 12]
z = [124 124 124]
x_sigma = [1010  2568  4600]
y_sigma= [124  124  124]
z_sigma = [124  124  124]

there are 3 sets of 3d coordinates. I want 3 spheres with translucent colour combination with radius (x,y,z) to (x_sigma,y_sigma,z_sigma). I tried many possibilites but dint work. could you please help me.

"with radius (x,y,z) to (x_sigma,y_sigma,z_sigma)"

Some of your x are negative; it does not make sense to use negative values as a radius.

Your x, y, and z values are not equal, but you indicate you want to use them as radius; are you looking for the 3D equivalent of an ellipse, different radius around different axes?

I do not understand the role of x_sigma, y_sigma, z_sigma.

Should the first sphere have one pole at (x(1), y(1), z(1)) and the other pole at (x_sigma(1), y_sigma(1), z_sigma(1)) ?
