3D contour plot

Hi,

I have a cubic and also I have the temperature of 20,000 points of this cubic volume. Also, the 3D coordinate (x, y ,z) of this cubic is availble. How could I plot this temprature contour?

Avaible data:

Coor(x,y,z) => 20000x3

T(K) => 20000x1

An example picture of my desired plot is attached.

Thank you very much.

griddata() to get a 3D volume of interpolated data. slice() on three panes to get the surface of the cube.
