How do I install mdenoise in GRASS 6.4.3? I've already successfully installed r.denoise, and have downloaded mdenoise from wget http://www.cs.cf.ac.uk/meshfiltering/index_files/Doc/mdsource.zip. How do I proceed now?
mdenoise seems to be a standalone command and cannot installed "in GRASS". You still can combine it with GRASS commands, of course.
Compile it on unix platforms with
g++ -o mdenoise mdenoise.cpp triangle.c
as described in the README file.
