How to apply conditions to fill an area in 3D space?

I wanted to fill an area in 3D space using some conditions on a vector.

Suppose the vector is:

x1 = 100;
y1 = 100;
z1 = 100;
v1 = [x1, y1, z1];

now I want to assign conditions for

v2 = [x2, y2, z2];

such as:

x2 < x1;
y2 < y1;
z2 < z1;
x1 - x2 < y1 - y2;
y1 - y2 < z1 - z2;

How can I apply these conditions and fill the area in 3D space for all possible values of v2?

I tried using the fill3 function but I am not sure if that is the best options.

Hi,

You can try something like this.

or you can use fimplicit3 function like this

f = @(x,y,z) x<1 & y<1 & z<1;
fimplicit3(f,[-100 100])

Hope this helps.
