What meshfile is

meshfile is a free C library for reading and writing 3D mesh formats on Linux and UNIX-style systems. It handles indexed triangle meshes, multiple objects per file, optional predefined vertex attributes, materials with optional texture maps, and optional transformation-node hierarchies. Supported formats are Wavefront OBJ, JTF, GLTF, 3DS, and STL. GLTF support is read-only, while STL support is binary-only. The library does not support quads, n-gons, triangle strips, or triangle fans, and animations are outside its scope. Its distribution includes meshview, an OpenGL 3D model viewer, and meshconv, a converter for supported formats. Developers can install it system-wide, include meshfile.h and link with -lmeshfile, or build the source into an application. It has no dependencies beyond libc. meshfile uses the GNU Lesser General Public License version 3 or later, with a stated requirement that applications incorporating its source and include directories be free software. Before version 1.0, API and ABI stability are not guaranteed.

Who it suits

It suits developers who need a small C library for triangle-mesh file conversion or viewing on Linux and UNIX systems. It is less suitable when animation or unsupported polygon types are required.

What it does well

Reads and writes several common mesh formats
Includes viewer and conversion utilities
No dependencies beyond libc
Can install system-wide or embed in applications
Free under LGPL version 3 or later

What to know first

GLTF support is read-only
STL support is binary-only
No quads, n-gons, strips, or fans
API and ABI stability are not guaranteed before version 1.0

Limits

GLTF files can be read but not written, and STL support is binary-only. The library excludes quads, n-gons, triangle strips, triangle fans, and animation; API and ABI stability are not guaranteed before version 1.0.

Getting started

Open the meshfile project site or GitHub repository
Clone the latest source or obtain a project-site or GitHub release
Build the library on UNIX with make
Install it system-wide and include meshfile.h with -lmeshfile
Alternatively, compile the source files directly into a free-software application
Build the included meshview viewer or meshconv converter as needed

Verdict

meshfile provides focused mesh-file handling with useful companion tools and minimal dependencies. Its format and geometry limits, licensing condition, and pre-1.0 stability caveat matter when choosing it for a project.

Questions

Is meshfile free?

Yes. It has a free plan and is released under the GNU Lesser General Public License version 3 or later.

Which platforms are supported?

The listed platform is Linux, and the build instructions describe building on UNIX with make.

Which formats can meshfile handle?

It supports Wavefront OBJ, JTF, GLTF, 3DS, and STL, with GLTF read-only and STL binary-only support.

Does meshfile support animation?

No. Animation is outside the library's scope.

What dependencies does it require?

The project describes zero dependencies beyond libc.

Can it be embedded in an application?

Yes. You can include meshfile.h and link with -lmeshfile, or build the source files into your program. The stated source-and-include-directory licensing route applies only to free software.
