stla_io


stla_io, a MATLAB code which includes routines to read or write the 3D graphics information stored in an ASCII STL (stereolithography) file.

Especially if you are reading large ASCII STL files, you might want to consider the STLA_SIZE_FAST and STLA_READ_FAST routines, provided by Bill Seufzer of NASA Langley. These will run more quickly in MATLAB than the routines STLA_SIZE and STLA_READ.
