v0.3.1

tyler 0.3.1 (2023-04-06)

Changed

• Add the proj crate as a submodule, because the proj-sys build script need to be changed so that proj-sys can be built with MYSYS2 on Windows (see georust/proj#156).
• Warning instead of error when the gltf export in the subprocess fails (fixes #36).
• The geoflow flowchart directory can be set at runtime with the TYLER_RESOURCES_DIR environment variable. By default, the directory is set to the CARGO_MANIFEST_DIR at compile time.
• Features are assigned to tiles based on their bounding box, instead of only their vertices (fixes #28).
• Update the geoflow docker image.
• Improve documentation.

v0.3.0

First public release of Tyler.
With this version Tyler can generate 3D Tiles v1.1 from CityJSONFeatures that are stored individually in files.

Details of the 3D Tiles output:

• The tileset content if binary glTF (.glb).
• The glTF assets contain feature metadata (per CityObject), using the EXT_mesh_features and EXT_structural_metadata extensions.
• The features are colored to default values, and the colors can by set per CityObject type.
• The glTF files are compressed, using the KHR_mesh_quantization and EXT_meshopt_compression extensions.
• Implicit tiling is supported (optional).

The current version depends on the geoflow-bundle for converting CityJSONFeatures to glTF.
Therefore, we strongly recommend to use the provided docker image for running Tyler.
