/** @page magnum-sceneconverter Scene conversion utility
@brief Converts scenes of different formats
@m_since{2020,06}
@tableofcontents
@m_footernavigation
@m_keywords{magnum-sceneconverter sceneconverter}
This utility is built if `MAGNUM_WITH_SCENECONVERTER` is enabled when building
Magnum. To use this utility with CMake, you need to request the
`sceneconverter` component of the `Magnum` package and use the
`Magnum::sceneconverter` target for example in a custom command:
@code{.cmake}
find_package(Magnum REQUIRED imageconverter)
add_custom_command(OUTPUT ... COMMAND Magnum::sceneconverter ...)
@endcode
See @ref building and @ref cmake and the @ref Trade namespace for more
information. There's also a corresponding @ref magnum-imageconverter "image conversion utility".
@section magnum-sceneconverter-example Example usage
Listing contents of a glTF file, implicitly using
@relativeref{Trade,AnySceneImporter} that delegates to
@relativeref{Trade,GltfImporter}, @relativeref{Trade,AssimpImporter} or
@ref file-formats "any other plugin capable of glTF import" depending on what's
available:
@m_class{m-code-figure}
@parblock
@code{.sh}
magnum-sceneconverter --info Box.gltf
@endcode
<b></b>
@m_class{m-nopad}
@include sceneconverter-info.ansi
@endparblock
Converting an OBJ file to a PLY, implicitly using
@relativeref{Trade,AnySceneConverter} that delegates to
@relativeref{Trade,StanfordSceneConverter} or
@ref file-formats "any other plugin capable of PLY export" depending on what's
available:
@code{.sh}
magnum-sceneconverter chair.obj chair.ply
@endcode
Processing an OBJ file with @relativeref{Trade,MeshOptimizerSceneConverter},
setting @ref Trade-MeshOptimizerSceneConverter-configuration "plugin-specific configuration options"
to reduce the index count to half, saving as a PLY, with verbose output showing
the processing stats:
@code{.sh}
magnum-sceneconverter chair.obj -C MeshOptimizerSceneConverter \
-c simplify=true,simplifyTargetIndexCountThreshold=0.5 chair.ply -v
@endcode

Arguments:
- `input` --- input file
- `output` --- output file; ignored if `--info` is present
- `-h`, `--help` --- display this help message and exit
- `-I`, `--importer PLUGIN` --- scene importer plugin (default:
@ref Trade::AnySceneImporter "AnySceneImporter")
- `-C`, `--converter PLUGIN` --- scene converter plugin(s)
- `--plugin-dir DIR` --- override base plugin dir
- `--map` --- memory-map the input for zero-copy import (works only for
standalone files)
- `--only-attributes N1,N2-N3…` --- include only attributes of given IDs in
the output. See @ref Utility::String::parseNumberSequence() for syntax
description.
- `--remove-duplicates` --- remove duplicate vertices using
@ref MeshTools::removeDuplicates(const Trade::MeshData&) after import
- `--remove-duplicates-fuzzy EPSILON` --- remove duplicate vertices using
@ref MeshTools::removeDuplicatesFuzzy(const Trade::MeshData&, Float, Double)
after import
- `-i`, `--importer-options key=val,key2=val2,…` --- configuration options to
pass to the importer
- `-c`, `--converter-options key=val,key2=val2,…` --- configuration options
to pass to the converter(s)
- `--mesh MESH` --- mesh to import (default: `0`), ignored if
`--concatenate-meshes` is specified
- `--level LEVEL` --- mesh level to import (default: `0`), ignored if
`--concatenate-meshes` is specified
- `--concatenate-meshes` -- flatten mesh hierarchy and concatenate them all
together @m_class{m-label m-warning} **experimental**
- `--info-animations` --- print into about animations in the input file and
exit
- `--info-images` --- print into about images in the input file and exit
- `--info-lights` --- print into about lights in the input file and exit
- `--info-materials` --- print into about materials in the input file and
exit
- `--info-meshes` --- print into about meshes in the input file and exit
- `--info-objects` --- print into about objects in the input file and exit
- `--info-scenes` --- print into about scenes in the input file and exit
- `--info-skins` --- print into about skins in the input file and exit
- `--info-textures` --- print into about textures in the input file and exit
- `--info` --- print info about everything in the input file and exit, same
as specifying all other `--info-*` options together
- `--color` --- colored output for `--info` (default: `auto`)
- `--bounds` --- show bounds of known attributes in `--info` output
- `-v`, `--verbose` --- verbose output from importer and converter plugins
- `--profile` --- measure import and conversion time
If any of the `--info-*` options are given, the utility will print information
about given data present in the file. In this case no conversion is done and
output file doesn't need to be specified. In case one data references another
and both `--info-*` options are specified, the output will also list reference
count (for example, `--info-scenes` together with `--info-meshes` will print
how many objects reference given mesh).
The `-i` / `--importer-options` and `-c` / `--converter-options` arguments
accept a comma-separated list of key/value pairs to set in the importer /
converter plugin configuration. If the `=` character is omitted, it's
equivalent to saying `key=true`; configuration subgroups are delimited with
`/`.
It's possible to specify the `-C` / `--converter` option (and correspondingly
also `-c` / `--converter-options`) multiple times in order to chain more
converters together. All converters in the chain have to support the
@ref Trade::SceneConverterFeature::ConvertMesh feature,
the last converter either @ref Trade::SceneConverterFeature::ConvertMesh or
@ref Trade::SceneConverterFeature::ConvertMeshToFile. If the last converter
doesn't support conversion to a file,
@ref Trade::AnySceneConverter "AnySceneConverter" is used to save its output;
if no `-C` / `--converter` is specified,
@ref Trade::AnySceneConverter "AnySceneConverter" is used.
If `--concatenate-meshes` is given, all meshes of the input file are
concatenated into a single mesh using @ref MeshTools::concatenate(), with the
scene hierarchy transformation baked in using
@ref SceneTools::flattenMeshHierarchy3D(). Only attributes that are present in
the first mesh are taken, if `--only-attributes` is specified as well, the IDs
reference attributes of the first mesh.
