v2.2.3
Fix 1. The osgdb_gltf plugin may cause errors in the parent-child relationship of nodes when handling empty grids; 2. The number of 3dtiles files converted from model23dtiles is fewer, the hierarchical division is more reasonable, and the degree of simplification is more appropriate; 3. Update the meshoptimizer library version to the latest version; 4. Lock the version of the ktx library (the latest ktx library vcpkg will generate an error when compiling).

v2.2.2
1. Fixed the issue where the osgdb_gltf plugin does not correctly support the KHR_materials_pbrSpecularGlossiness extension; 2. Fixed the issue where the model23dtiles tool was unable to set the quadtree structure; 3. Fixed the issue where the model23dtiles tool lost model components when generating kd trees; 4. When exporting i3dm or b3dm tiles, the osgdb_gltf plugin will save the name of the model component in a property named "GeodeName" regardless of whether the model has attribute information.

add 1. Added support for models with vertex coordinates in the projection coordinate system (limited test data, only models exported from cityengine 1.were tested, and there may be issues with models exported from other software). fix 1. Material loss issue during import of some FBX models.

v2.0.1
fix 1. The issue of returning true for different textures when comparing them can result in an incorrect texture atlas being constructed. 2. When reading the FBX model, there is no need to perform additional processing on the upward axis. 3. When reading the FBX model, modify the default settings for metallicity and roughness values.

v2.0.0
Refactor code to remove unnecessary content 1. Refactored osgdb_gltf plug-ins, added support for B3DM and i3DM formats, and added support for KHR_materials_unlit, KHR_mesh_quantization, and KHR_texture_transform extensions. 2. osgdb_ktx plugin supports Mipmaps. 3. Remove osgdb_b3dm plugins. 4. Add texturepacker tool for texture atlas packaging. 5. Add simplifier tool for mesh simplification of the model. 6. Reconstruct the model23dtiles tool, support the export of tiles in i3dm format, add more parameters, reconstruct the calculation method of geometricError, reconstruct the construction of hlod trees, and significantly improve the performance of output tiles.

v1.0.0
1.Support for exporting glb/gltf files (exported files can be compressed with vertices (draco, meshopt), and textures (ktx2, webp)) 2.Supports reading fbx files with pbr or physical materials exported by 3dmax software 3.Support exporting b3dm files with batchid and attribute information (exported files can be compressed with vertices (draco), and textures (ktx2, webp)) 4.Support for exporting super compressed ktx 2.0 files 5.Support for exporting .webp files 6.Provide a tool for converting glb files from b3dm 7.Provide a tool for converting 3D models (excluding oblique photography) into 3D tiles. The exported 3D tiles support quadtree and octree structures TODO 1.Some parameters for Draco compression have not been released yet, and the next version aims to open them up 2.The compression efficiency of meshopt is not as good as that of gltfpack and needs to be optimized 3.The webp plugin cannot parse grayscale images 4.The 3dtiles conversion tool is slow and needs to be optimized 5.The gltf plugin supports meshopt compression, and theoretically the b3dm plugin can also support it, but it has not yet been able to open parameters in the b3dm plugin 6.Compilation requires the use of libraries such as fbxsdk and modified tinygltf. Due to the large size of the file, it cannot be uploaded. In the future, I will upload it to Baidu Netdisk
