mago-3d-tiler v1.15.4

mago-3d-tiler v1.15.4

This release introduces Geoid height support and vertical skirt generation for photogrammetry tiles.
You can now easily convert datasets based on orthometric height (MSL) to ellipsoidal height.

In addition, this version includes a custom temp directory option and major improvements to point cloud conversion performance and stability.

[Feature Additions]

• Geoid Height Support
  By default, heights are handled based on the ellipsoid.
  You can apply the built-in EGM96 geoid or specify a custom external geoid file.
  Usage example:
  --geoid EGM96
--geoid {custom_geotiff_path}

• Custom Temp Directory Option
  You can now specify a custom temporary directory.
  This can help improve performance, for example by using an SSD as the temp path.
  Usage example:
  --temp /work/temp

• Photogrammetry Vertical Skirt Support
  Adds vertical skirts to photogrammetry tiles to reduce visual gaps between tiles.

[Feature Improvements]

• Point Cloud Conversion Performance & Stability Improvements

  • Improved memory stability by applying chunk-based tiling to prevent memory leaks
  • Improved conversion speed through internal optimization and faster point shuffling

• i3dm (GPU Instancing Model) Conversion

  • Slight reduction in memory usage during conversion

• b3dm (Batching Model) Conversion Improvements

  • Improved conversion efficiency by pre-creating temp resources

• Tile Generation Flow Improvement

  • Content is now generated starting from the root node

mago-3d-tiler v1.14.0-release

mago-3d-tiler v1.14.0-release

Work has been busy, but I wanted to push a meaningful update before FOSS4G.
Next, I plan to focus mainly on improving performance/stability and GIS Vector conversion features.

[Feature Additions]

• (🧪Experimental) Earth Curvature Correction
  Can be applied when curvature correction is required.
  Useful for some datasets using Cartesian 2D coordinate systems.
  Usage example: --curvatureCorrection or shorthand -cc

• (🧪Experimental) SplitByNode option
  If the input scene is organized with buildings as separate nodes,
  you can now split them and tile per-building automatically.
  Usage example: --splitByNode or shorthand -sbn

[Feature Improvements]

• Photogrammetry Quality Enhancements
  Reduced the visual gap between low LOD and high LOD.
  (Performance will be improved further in later releases.)

• Misc transform-related tests & improvements

• Mesh Quantization improvements + bug fixes

mago-3d-tiler v1.13.1-hotfix

mago-3d-tiler v1.13.1-hotfix

[Hotfix]

Fixed bug with --merge function after v1.13.0-release update

• Depending on the version of tileset.json you want to generate, you can apply the --tilesVersion 1.1 option.

mago-3d-tiler v1.13.0-release

mago-3d-tiler v1.13.0-release

This release adds initial support for the 3D Tiles 1.1 specification and introduces ECEF (EPSG:4978)-based tiling.
The ECEF feature is in an early stage and will be improved based on future feedback.

[Feature Additions]

Support for 3D Tiles 1.1 Specification

• The default tileset version is now 1.1.
• You can still generate tiles in the 1.0 format by using the option:

  --tilesVersion 1.0

• Legacy tile formats (b3dm, i3dm, pnts) have been replaced with glTF (.glb) based structures.
• Extension handling has been updated to use both Tileset and glTF extensions as specified in the 1.1 standard.

ECEF (Earth-Centered, Earth-Fixed) Tiling Support (EPSG:4978)

• Add support for ECEF Cartesian tiling using:

  --crs 4978

• BoundingVolume box generation is based on the Cartesian center of the Earth.

Enhanced Tile Transform Features

• Reworked internal handling for:
  • Y-Up correction
  • Scale
  • Rotation
  • Translation
    These changes improve alignment across CRS and 3D engine compatibility.

[Deprecated]

The following options have been deprecated in this release and will be removed in a future version:

• Experimental features removed

  • --largeMesh
  • --voxelLod

• Replaced by --rotateXAxis feature

  • --autoUpAxis
  • --swapUpAxis
  • --flipUpAxis

mago-3d-tiler v1.12.0-release

mago-3d-tiler v1.12.0-release

This release includes major feature additions and fixes, notably support for Photogrammetry conversion and the GeoPackage format. We've also added support for point cloud intensity/classification properties, the ability to generate i3dm from polygons, and more.

As a side note, I'm working on automating release note generation from PRs, since writing them manually is quite tedious.

[Feature Additions]

GeoPackage format support.

• Converts geometry-only GeoJSON and SHP files into extrusion/pipe/i3dm tiles.

i3dm: Automatically Create Point Instances from Vector Polygons

• Conversion can be controlled using density and scale values.
• Useful for tree datasets (e.g., clinical chart data).
• New CLI options:
  • --densityColumn "density_value"
  • --scaleColumn "scale_value"

Add Photogrammetry Tiling feature

Used to process mesh data generated by photogrammetry method.
Generated by b3dm but can be executed by adding --photogrammetry option.

• Split and rearrange large 3D model data
• Automatically generate models with LODs

• This feature utilizes GPU and may not work properly on devices that do not recognize GPU.

Point Cloud Intensity/Classification Properties Added

• INTENSITY and CLASSIFICATION properties added to the .pnts file BatchTable.
• Example usage in CesiumJS:

  tileset.style = new Cesium.Cesium3DTileStyle({
      color: "rgb(${INTENSITY}, ${INTENSITY}, ${INTENSITY})"
  });

Multi-Geotiff support for terrain data

You can now specify terrain paths in the form of directories.
You can use both --terrain /data/terrain.tif and --terrain /data/terrains.

• However, it may have a performance impact.

Add Tileset merge function

Search for tileset.json files in a subfolder by output path and run
and link them.

You can do this by passing /parent as an argument to input and output when you have a directory structure like the one below.

/parent/
/parent/child1/tileset.json
/parent/child2/tileset.json
/parent/child3/child1/tileset.json
/parent/child4/child1/tileset.json
...

Example usage:

--input <arg> --output <arg> --merge 

[Feature Improvement]

• The JAR File is now unified and no longer split by platform (Windows, Linux, macOS).
• A floor plane has been added to extrusion models, allowing classification with CesiumJS.
• Improved automatic CRS detection when reading GIS vector and LAS data, even if the -crs flag is not provided.

[Bug Fix]

• Fixed a normalization bug in geometry processing.
• Resolved an issue where z height values became NaN when converting polylines.
• Fixed the refineAdd bug so it is now always applied when working with Vector2D data.

[Deprecated]

• The --zeroOrigin option has been deprecated.

mago-3d-tiler v1.10.0

[Changed in version 1.10.0]

In this release we wanted to improve memory issues with the overall large data conversion process.
We have lightened the point cloud tile results and made it possible to convert larger point cloud data.
We also made the CityGML conversion more compatible.

[Feature Additions]

• Support for converting large point cloud files
  Improved memory stability by changing the way points are stored in temporary files during conversion instead of in memory.
  which is more memory stable, but slower.

• Apply quantisation to point cloud tiles. Quantization the resulting data to make it lighter.

• Changed point cloud options to include.
  Removed the --pointSkip and --pointScale options.
  Added an option to convert to point cloud source-level point counts Available with options --sourcePrecision, -sp
  Added option for percentage of points relative to the point cloud source
  --pointRatio {100}, -pr {100}
  Available as options Values from 1 to 100, default is 50%

• Changed option to fix Y-UP Axis Z-UP Axis issue, added as X-Axis rotation feature,
  Using --swapUpAxis, --flipUpAxis options is now not recommended, will be removed in next release.
  Can be used with --rotateX {degree}, -rx {degree} instead

--swapUpAxis -> --rotateX "-90.0"
--flipUpAxis -> --rotateX "180.0"

Note that the ‘-’ character can cause problems with negative separators and option separators.

• Added transformation offset options

--xOffset {X Offset}
--yOffset {Y Offset}
--zOffset {Z Offset}

When transforming data, you can give an offset for each axis. Units are determined by projection.
Also available as :

-xo {X Offset}
-yo {Y Offset}
-zo {Z Offset}

• Reduced memory usage for Shape and Geojson conversion features.
• Improved CityGML conversion compatibility, now converts most tags.

[Feature Improvements]
