FAQ
H4 to STL Conversion
What are H4 files?
H4 is a file extension used for HDF4 (Hierarchical Data Format, Release 4), a general-purpose format for scientific data created at the National Center for Supercomputing Applications (NCSA) in the United States and now maintained by The HDF Group. A file works as a container in which many kinds of data are stored together with descriptions of what they are: large arrays of measurements, images with color palettes, tables, and notes. Because it is independent of the computer that created it, it became a favorite of researchers. In 1993, NASA chose HDF4 as the format for data from its Earth Observing System, and satellite products such as those from the MODIS instrument were distributed in it for many years. The same files often use the .hdf extension.
What are STL files?
STL is the proprietary format for a computer-aided design (CAD) program developed by 3D Systems. STL is an acronym for Stereolitography, which is a type of technology used for creating prototypes or patterns through 3D printing. An STL file contains a surface representation of such a model, without detailed specifications of aspects such as colours. STL files can only be opened with a limited number of programs.
