Subject: Interpolate real z value of all nodes from dem data.
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=903ac38cfff0cc948c077c6cc2aa3b1202de825e;p=flightgear.git

Interpolate real z value of all nodes from dem data.
Write scenery file to correct location.
Pass along correct triangle attributes and write to output file.
