MONOCEROS 3DGS THIRD-PARTY NOTICES

Monoceros 3DGS is proprietary software. The following components remain under
their respective licenses. Selling or licensing Monoceros does not alter these
terms. Full license texts are in the adjacent licenses directory. Exact source
versions and build inputs are recorded in COMPONENTS.json and the separately
published third-party source archive.

Nunito ExtraBold Latin font 3.602
  Use: embedded toolbar branding typeface; WOFF2 decompressed to TrueType.
  License: SIL Open Font License 1.1; copyright and full terms in
       licenses/Embedded/Nunito-OFL.txt.

APPLICATION AND LINKED DEPENDENCIES

QtBase 6.11.1
  Project: https://www.qt.io/
  Use: dynamically linked Core, Network, Gui, Widgets, OpenGL, OpenGLWidgets and
       the minimal XCB/image-format/TLS plug-ins staged with the application.
  License route: GNU LGPL v3 for the selected open-source components, with the
       applicable GNU GPL text and Qt GPL exception included as distributed by
       Qt. Qt's bundled third-party license texts are retained under licenses/Qt;
       the conservative complete QtBase source attribution roll-up is in
       QtBase-6.11.1-THIRD_PARTY_ATTRIBUTIONS.txt.
  Modifications: no source modification; configured as a shared release build.
  Source/relinking: see SOURCE_OFFER.txt.

Monocypher 4.0.2 (0d85f98c9d9b0227e42cf795cb527dff372b40a4)
  Project: https://monocypher.org/
  Use: statically linked standard Ed25519 verification of model manifests.
  License choice: BSD-2-Clause; unmodified upstream source.
  License text: licenses/Monocypher/LICENSE.md.

Ubuntu OpenSSL 3 TLS provider (Linux system library)
  Build snapshot: 3.0.2-0ubuntu1.29; runtime security updates are OS-managed.
  Use: Qt Network HTTPS; libssl.so.3 and libcrypto.so.3 are not bundled.
  License: Apache-2.0; licenses/SystemInterfaces/OpenSSL-copyright.txt.
  Windows uses the system Schannel provider instead.

Eigen 3.4.0
  Project: https://eigen.tuxfamily.org/
  Use: header-only linear algebra compiled into Monoceros and its static
       dependencies.
  License: primarily Mozilla Public License 2.0. Release builds define
       EIGEN_MPL2_ONLY so LGPL-only Eigen modules cannot enter the build.
  Source: see SOURCE_OFFER.txt and licenses/Eigen.

fast_float 8.0.2 (50a80a73ab2ab256ba1c3bf86923ddd8b4202bc7)
  Project: https://github.com/fastfloat/fast_float
  Use: unchanged header-only, locale-independent floating-point XML parsing.
  Copyright (c) 2021 The fast_float authors.
  Selected license: MIT; licenses/Embedded/fast_float-MIT.txt.

nlohmann/json 3.11.3
  Project: https://github.com/nlohmann/json
  License: MIT.

OpenCV and opencv_contrib 4.5.4
  Project: https://opencv.org/
  Use: minimal static core/imgproc/flann/features2d/calib3d/aruco build.
  Licenses: Apache License 2.0 and retained BSD 3-Clause notices for older
       source sections. OpenCV-derived files are also identified below.

OpenCV QR ArUco source port (4.13.0, fe38fc608f6acb8b68953438a62305d8318f4fcd)
  Project: https://github.com/opencv/opencv
  Copyright (C) 2018, Intel Corporation, all rights reserved.
  Third party copyrights are property of their respective owners.
  Use: private straight QR detector/decoder plus modern ArUco finder grouping;
       existing linked OpenCV4.5.4 remains unchanged.
  Modifications: isolated namespace, bounded caller-owned concurrency, shared
       threshold image, finder geometry/mirror output, no file IO.
  License: Apache-2.0; licenses/Dependencies/Apache-2.0.txt.
  Included sampled-grid quirc decoder: Copyright (C) 2010-2012 Daniel Beer;
       ISC terms in licenses/Embedded/quirc-ISC.txt. Recognizer not included.

Ceres Solver 2.0.0
  Project: https://ceres-solver.org/
  Use: static miniglog build. Linux enables EigenSparse plus the audited
       SuiteSparse no-GPL provider; Windows retains EigenSparse only. CXSparse,
       LAPACK, tests, and examples are disabled. The Linux build additionally
       disables SuiteSparseQR covariance. Monoceros patches Ceres's discovery,
       public component contract, and covariance implementation so SPQR is
       neither compiled nor linked; the exact patch is in the corresponding-
       source archive. The selected private-Schur patch adds worker-private
       high-incidence normal cells and right-hand sides without enabling any
       omitted SuiteSparse module; it is included in the same source archive.
  License: New BSD, with bundled license notices reproduced in
       licenses/Dependencies/Ceres-LICENSE.txt.

SuiteSparse 5.10.1 no-GPL subset (Linux package)
  Project: https://github.com/DrTimothyAldenDavis/SuiteSparse
  Use: dynamically linked CHOLMOD Core, Check, Cholesky, and Partition modules,
       with SuiteSparse_config, AMD, CAMD, COLAMD, CCOLAMD, and METIS. The build
       defines NGPL and physically omits MatrixOps, Modify, Supernodal, GPU, and
       SPQR objects. A patched installed header marks this exact audited build;
       final package verification rejects SPQR and excluded CHOLMOD symbols.
  Licenses: retained CHOLMOD modules are LGPL 2.1-or-later; AMD-family ordering
       components are BSD 3-Clause; METIS is Apache 2.0; SuiteSparse_config states
       no licensing restrictions. Exact notices and modification description are
       in licenses/Dependencies/SuiteSparse-5.10.1-NGPL-NOTICES.txt.
  Source/relinking: see SOURCE_OFFER.txt. Compatible replacement shared libraries
       may be installed under the same LGPL replacement contract as Qt/libexif.

OpenGV 1.0, commit 91f4b19c73450833a40e463ad3648aae80b3a7f3
  Project: https://github.com/laurentkneip/opengv
  Use: statically linked central-camera geometry.
  License: BSD 3-Clause.
  Modification: the release build replaces upstream -march=native with the
       portable -march=x86-64 -mtune=generic baseline. The patch is included in
       the corresponding source archive. Monoceros's private OpenGV ABI adapter
       uses the identical architecture and C++ ABI flags.

libjpeg-turbo 3.1.1
  Project: https://libjpeg-turbo.org/
  Use: static JPEG codec.
  Licenses: IJG, modified BSD, and zlib terms as described in the retained
       license. This software is based in part on the work of the Independent
       JPEG Group.

  Project: http://www.libpng.org/pub/png/libpng.html
  Use: static PNG codec.
  License: libpng License.

  Project: https://github.com/AcademySoftwareFoundation/Imath
  Use: statically linked numeric types required by OpenEXR.
  License: BSD 3-Clause.

OpenEXR 3.1.13
  Project: https://github.com/AcademySoftwareFoundation/openexr
  Use: static PXR24 codec for bounded intermediate depth state.
  License: BSD 3-Clause.

Zstandard 1.5.7
  Project: https://github.com/facebook/zstd
  Use: static project-pack compression.
  License: BSD 3-Clause.

libspnav 0.2.3 (Linux)
  Project: https://spacenav.sourceforge.net/
  Use: statically linked SpaceMouse client, native UNIX socket only.
       Includes local connection-lifetime fixes (allocation cleanup and valid fd 0).
  License: BSD 3-Clause; see licenses/Dependencies/libspnav-BSD-3-Clause.txt.
       The spacenavd device driver is not bundled; users install it separately.

libexif 0.6.25
  Project: https://github.com/libexif/libexif
  Use: dynamically linked, user-replaceable EXIF reader.
  License: GNU LGPL 2.1. Corresponding source and build inputs are in the
       separately published third-party source archive.

GStreamer 1.20 (Ubuntu 22.04 system provider)
  Project: https://gstreamer.freedesktop.org/
  Use: dynamically linked operating-system video provider on Linux.
  License: core/base libraries are LGPL 2.1-or-later. Monoceros does not bundle
       GStreamer codec plug-ins. Users install codec plug-ins through Ubuntu.

shaderc/glslc 2024.4
  Project: https://github.com/google/shaderc

       3f17b2af6784bfa2c5aa5dbb8e0e74a607dd8b3b dependencies.

Khronos Vulkan loader/headers and OpenCL ICD loader/headers
  Use: wrapper build/runtime interfaces. GPU drivers and vendor ICDs are not
       distributed by Monoceros.
  Licenses: Apache 2.0 and the package-specific permissive notices reproduced
       under licenses/SystemInterfaces.

NVIDIA CUDA 13.3 redistributable components
  Project: https://developer.nvidia.com/cuda-toolkit
  Runtime payload selected from NVIDIA's CUDA 13.3 redistribution manifest:
       CUDA Runtime 13.3.29, cuBLAS 13.5.1.27 (including cuBLASLt), and nvJPEG
       13.2.0.21 where present in the final dependency closure.
  Build-only pinned components additionally include NVCC/NVVM/CRT/CCCL and
       OpenCL headers. The NVIDIA display driver and libcuda are not bundled.
