ResIL started as a fork of DevIL and is actively maintained to use up-to-date libraries. The API has been updated to work with several threads. Countless fixes have been applied, much of the code base has actually been rewritten to enhance stability. Support for webp has been added. ResIL focuses on robust decoding so that even partially corrupted images can be displayed without crashes or exceptions.
...ImatiSTL provides both functions for local mesh repairing and methods for global remeshing. Local repairing is useful when the available data must remain exactly as it is in the input STL file, whereas global remeshing may fix even highly corrupted meshes at the cost of a small distortion in the resulting fixed mesh.
