How Can I Create a Tin from Elevation Points in QGIS

[المشرف العام]

I have a shapefile of points with values that represent elevation at the given point. I know that I can create a TIN from these points, but the fields in the TIN do not represent the elevation. Rather, they represent an ID field for each node in the triangle.

I can also use the Interpolation plugin with Triangulated interpolation as the method. However, in this case it produces a DEM.

How can I produce a TIN where each node in the TIN represents the elevation at that point?

Thanks
