v0.3.2

Second Hotfix for v0.3 (0.3.0 & 0.3.1)

• Fixed faulty Linux build
• Fixed Linux binary being debug build
• Fixed completely missing shapes when LoD1.3 and 2.2 encounters issues

V0.3.1

First Hotfix for v0.3.0

• Fixed very slow obj writing speed
• Improved is glass detection for panel objects

V0.3.0

Major update of core functionality of the software, the primary focus was computing speed and stability. Linux build has not been tested.

• Added LoD4 (4.0, 4.1, and 4.2) to support 1:1 conversion/mapping
• Added automatic footprint height detection (based on the BIM Base IDS of DigiGO)
• Added voxel pre-filtering bypass
• Drastically improved voxelisation related processes
• Improved indexing speed
• Improved LoD3 surface detection accuracy
• Improved roof detection code
• Changed data storage logic, slightly improving stability and reducing overhead
• Fixed incorrect face rotation output

known issues:

• Sometimes no or almost no geometry is output
• Application can hardcrash during indexing, rerunning resolves the issue
• During LoD4.2 processes the application can encounter objects that cause a hardcrash
• Merging surface processes can be extremely slow
• Extremely small surface can cause issues (1mm area and smaller)

V0.2.6

Third Hotfix for official release V0.2.3

• Added LoD0.0 footprint logic
• Added nested object access for LoD0.2 and 0.3 storey extraction
• Changed memory logic to improve nested object access
• Changed point on surface logic from area based to barycentric based
• Changed line surface intersection logic from signed volume to normal direction augmented with barycentric based
• Changed semantic data of roof and ceiling projections to custom type
• Fixed bug in point on line code that would incorrectly consider points to be on certain lines
• Fixed bug that could cause crash if empty roof geometry containers were encountered
• Fixed bug when attempting to create a plane with two equal points
• Fixed bug that would not store local transformations if IFC had no map conversion data

V0.2.5

Second Hotfix for official release V0.2.3

• Added tessellation logic to LoD3.2
• Added option to disable window and door simplification
• Added option to selectively omit objects from window and door simplification process
• Added option to select tolerances (buggy)
• Changed "simplify geometry" name setting to "Ignore void"
• Changed GUI layout
• Improved triangle surface point grid population
• Improved Planar face detection
• Fixed ray cast bug that could case surfaces to be incorrectly kept
• Fixed bug that could cause empty geometry objects to be output
• Fixed bug that could cause LoD0.2 surfaces to be placed incorrectly
• Fixed inconsistent tolerances
• Improved stability and computing speed

Full Changelog: v0.2.4...v0.2.5

V0.2.4

First Hotfix for official release V0.2.3

• Fixed issue where voxel shape would not export if no interior spaces were created
• Fixed issue where unrecoverable product shapes would cause a crash
• Fixed issue where Invalid shapes would cause a crash
• Fixed issue where unexpected shape extrusions would cause a crash
• Added IfcBeam objects to default div objects
• Multithreaded face splitting code (noticeably computing speed improvement for LoD0.3, 0.4, 1.3 and 2.2)
• Reduced complexity of LoD13 and 22 related Boolean processes to reduce the chance of unexpected behavior

V0.2.3

Summary:
Official update from V0.1.13 covering improved stability, improved computing speed, and expanded versatility.
New functionality cover 1:1 conversion option, site conversion option, alternative output formats (OBJ and STEP) and a drastically improved handling of small and complex surfaces.

Please note: This will be the final big update while funded by the CHEK project.

Notes:
Builds on V0.2.2:

• Added Logic to support multiple footprint shapes per building
• Added logic to support multiple objects to have the same name
• Added (a lot of) safeguards to prevent hard crashing
• Improved raycasting logic
• Improved voxel to shape logic
• Improved face tessellation logic
• Improved Pset data acquiring logic
• Changed face grouping logic (faces with same LoD of the same building are now grouped in a single geometry object)
