I started to study TIN in QGIS and created my first TIN from a point layer with elevation. There are two interpolation methods called Linear and Clough-Toucher that give very different results. Linear looks like a regular Raster and with Clough-Toucher the result cannot be interpreted at first glance. Further the values of both methods vary a lot, as can be seen in the picture.
I cannot find information in the QGIS Docs what the difference is between the two methods.
What is the difference and why are the results so different?
I am using QGIS 3.4.13.
