[postgis-users] ST_Buffer internals

Hi All, I am wondering how ST_Buffer computes a buffer around say a LINESTRING? How can I look at the internals of this? Is it possible to achieve the same effect using GDAL's C++ API? I ask because I have a very large LIDAR 3-D data set which I cannot load into Postgis, but I would certainly want
