I've just spotted an interesting issue with the TIN interpolation code.
With the TIN interpolation "linear" method, the rendering is fine (tin-linear.png), but with the "cubic" method, the code inserts 0 values instead of nodata until it hits the first non-nodata value (see the black part at the top of tin-cubic.png).
Marco, you are our only hope ;) I've looked into the code, but couldn't get my way through it.
