# Upstream doesn't bundle some things anymore, it looks for a system copy and downloads it if not found
# We should consider packaging libE57Format separately, but I don't think anything else needs it
Source4:	https://github.com/asmaloney/libE57Format/archive/refs/tags/v2.3.0.zip
# I know there is at least one other consumer of libigl, but as a header only library... bundle here too.

# This nexus is not the same as the nexus package in Fedora.
# This nexus is a c++/javascript library for creation and visualization of a batched multiresolution
# 3D model structure
Source6:	https://www.meshlab.net/data/libs/nexus-master.zip
# It also needs corto, a library for compression and decompression meshes and point clouds (C++/Javascript)
Source7:	https://www.meshlab.net/data/libs/corto-master.zip
# Long bundled, now pulled out of the source tarball, it's OpenCTM!
# Could be made into it's own package, but A) it is very old and B) unlikely anything else needs it
Source8:	https://www.meshlab.net/data/libs/OpenCTM-1.0.3-src.zip
# Meshlab's fork of StructureSynth, the original is very old
Source9:	https://github.com/alemuntoni/StructureSynth/archive/refs/tags/1.5.1.zip
# Meshlab depends on tinygltf 2.6.3, which is not current.
# tinygltf is a header-only library, so bundle party fun time
Source10:	https://github.com/syoyo/tinygltf/archive/refs/tags/v2.6.3.zip
# Meshlab depends on u3d 1.5.1, which is slightly better than when it depended on a fork of u3d.

%description
MeshLab is an open source, portable, and extensible system for the
processing and editing of unstructured 3D triangular meshes.  The
system is aimed to help the processing of the typical not-so-small
unstructured models arising in 3D scanning, providing a set of tools
for editing, cleaning, healing, inspecting, rendering and converting
these kinds of meshes.
