This change supports instancing functionality within the conversion process. * geometry processing with improved instance handling Adds instance registry for managing geometry paths Refactors fragment collection for more efficient processing Clarifies logic for transforming and processing geometries * improves geometry instance processing Enhances the handling of geometry instances by capturing world transformation data and ensuring proper registration. Updates the method for processing path fragments to return instance world data, allowing for improved conversion and registration of instances. Fixes potential logic bottlenecks in instance transformation retrieval. * adds instance fragment registry implementation Introduces a new interface and concrete class for managing instance fragments, including functionality for grouping, conversion tracking, and world coordinates. Improves structure for better management of instance data within the application. * removes old geometry helper methods and adds new functionality Introduces a new structure for axis-aligned bounding boxes, enhancing spatial computations. Implements various geometric transformation methods to support unbaking and processing geometry data. Improves vector comparison and bounding box calculations for improved accuracy. * updates Aabb structure and improves geometry processing Changes Aabb from a struct to a record type, enabling immutability and simpler construction. Enhances geometry processing logic to ensure valid Aabb computation, allowing for improved handling of empty geometries. Throws exceptions for null or invalid input in instance registration, ensuring greater robustness. * adds instancing support and geometry unbaking Implements instancing to optimise geometry handling and enables unbaking geometry for validation of instance detection. Enhances diagnostics reporting for instance grouping and tracking, improving clarity on geometry processing outcomes. * optimises geometry processing and visibility checks Enhances performance by pre-allocating list capacities to reduce resizing overhead. Implements a single-pass filter to improve visibility checks on model items, ensuring only geometries with both visibility and geometry are processed. Cleans up and simplifies the code by removing unnecessary debug logs. * adds diagnostics for instance grouping behaviour Implements a diagnostics class to analyse instance grouping efficiency and effectiveness within the application. Provides methods for generating detailed reports and summaries, aiding in debugging grouping failures and offering recommendations for improvement. * adds geometry cache statistics logging Implements a logging feature for geometry cache performance statistics, providing insights into COM extraction and geometry creation times. Updates the display value extractor to allow access to geometry statistics. Improves diagnostic capabilities by logging additional performance metrics during the geometry conversion process. * improves performance tracking and diagnostics in processing Enhances the timing and diagnostics for model item retrieval, providing detailed performance metrics to identify bottlenecks. Updates user feedback mechanisms during operations to maintain responsiveness. Refines the management of component instances in geometry processing for better efficiency. * addresses memory leaks COM object management in geometry processing Improves memory management with proper release of COM objects in the geometry processing system. Adds safety checks and optimisations within existing methods to prevent memory leaks and enhance performance. Relates to improved instancing capabilities. * removes deprecated settings code and cleans up logic Eliminates the previous implementation of conversion settings, streamlining settings management. Refines the conversion settings factory by removing unused methods and comments, optimising the overall process for better readability and maintenance. Updates the user-related configurations to enhance clarity and usability. * updates primitive processor documentation and comments Clarifies COM interop bottlenecks and performance analysis.

Refactors material name creation and streamlines object addition to proxies for improved performance and clarity. Introduces a settings manager to efficiently manage visual representation and related settings for model-specific caching. * formatting * fixes CI error CS9113 Replaces a local display value extractor reference with a class-level field for consistency and improved readability. The logging is only during DEBUG session so error was hidden until CI build * refactors element selection service integration Replaces the existing element selection service with a new implementation to improve clarity and maintainability. Updates service registrations and filters to use the refactored service while removing outdated functionality. Incorporates updates to ensure consistent geometry validation checks. * updates selection handling in geometry converter Replaces direct model item usage with a collection for selection handling, improving memory management by adding a dispose call. Enhances overall stability and performance of geometry conversion process. * optimises display values aggregation logic Refactors the method for aggregating display values from sibling bases. Utilises LINQ to streamline the accumulation process, enhancing readability and performance. Maintains functionality while reducing code complexity. * adds null check for item.Model in category extractor Ensures that the extraction process safely handles cases where item.Model is null, preventing potential runtime errors. Improves reliability of the converter's operation. * removes debug diagnostics for instance grouping Eliminates extensive logging and performance measurement related to instance grouping from the codebase. Streamlines the overall code by removing unused functionality related to diagnostics that was not leading to meaningful insights. This improves maintainability and clarity by reducing complexity in the relevant components. * apply Y-up to Z-up transform to instance matrices Instanced objects from Y-up models were incorrectly positioned because instance transforms used the raw Navisworks matrix while geometry vertices had already been converted to Z-up in PrimitiveProcessor. Added TransformMatrixYUpToZUp() which applies P * M * P^-1 conjugation to transform the entire 4x4 matrix to Z-up coordinate space. Applied to both the unbake operation and instance proxy transform when the model is not upright. --------- Co-authored-by: Oğuzhan Koral <45078678+oguzhankoral@users.noreply.github.com>	2026-01-15 13:42:52 +03:00
