C library for geometry input/output
===========================================
gmio is a reusable C library whose purpose is to provide complete I/O
support for various CAD file formats (eg. STL)
gmio aims to be [fast](https://github.com/fougue/gmio/wiki/4.-Benchmarks),
portable (ISO-C90 conformance) and feature-rich.
Main highlights:
* [x] "Abstract" streams that does not tie the user to C stream (`FILE*`).
gmio provides a general stream structure based on callbacks, so that
any kind of device can be used (memory, file, socket, ...)
* [x] Operations can be easily aborted
* [x] Buffering of input/ouput for efficient device usage
* [x] Available under the CeCILL-B license, which is fully BSD compatible
Supported CAD files format
==========================
Current version only supports the STL file format (STereoLithography), but support is complete :
* [x] Binary(little/big endian) and ASCII formats
* [x] Header data and "attribute byte count" for binary format
* [x] Name of solid for ASCII format
* [x] Detection of the input data format
* [x] Ability to specify the text formatting to represent float values
In addition, the STL module has the following advatanges:
* [x] The user keeps its own geometry data structures, no conversion needed.
This reduces the effort so that the user just specifies callbacks for
retrieval/creation of geometry data
* [x] No dynamic memory allocations
* [x] Extended support of OpenCascade's `StlMesh_Mesh`
Building gmio
===============
gmio can be built with CMake, by default a static library is generated.
Read the [Build instructions](https://github.com/fougue/gmio/wiki/2.-Build-instructions)
How to report a bug
===================
If you think you have found a bug in gmio, we would like to hear
about it so that we can fix it. The gmio bug tracking system is
open to the public at https://github.com/fougue/gmio/issues.
Before reporting a bug, please use the bug-tracker's search functions
to see if the issue is already known.
Always include the following information in your bug report: the name
and version number of your compiler; the name and version number of
your operating system; the version of gmio you are using, and
what configure options it was compiled with.
If the problem you are reporting is only visible at run-time, try to
create a small test program that shows the problem when run.
