If the points in time and space are uniformly sampled, I'd just create a 
2-D vtkImageData with temperature as an associated data array.  Then use 
ParaView's "warp by scalar" filter to create a surface.

(If they are not regularly sampled, use a vtkRectilinearGrid or 
vtkStructuredGrid.)

You would need C++ to make use of the VTK libraries for creating files. 
  My preferred way of translating data into VTK format is to use the VTK 
libraries in Python to access the vtkXMLImageDataWriter class.
