Mar 1, 2026March 2026 (2026-03) monthly summary for OpendTect/OpendTect focusing on delivering robust UI for Horizon and data selection, refactoring core data handling with improved export workflows, and strengthening stability for LASWriter and Geobody components. Key outcomes include a more efficient and intuitive data selection experience; more reliable import/export pipelines with factory-based architecture and Z-domain export; and improved system resilience with guards against narrow column widths and improved iso-value handling, reducing crash risk during polygon and iso-value body creation. The work supports large data sets and data integrity for exports and geobody analyses, validated by large-scale tests and end-to-end workflows. Key achievements: - UI/UX Enhancements for Horizon and Data Selection: robust multi-file selection, improved color description layout, translator icons, HorizonData multi-select, and UI event handling; validated with 3000+ file imports. - Core Data Handling and Export Improvements: factory-pattern refactor for PointSet/Polygon import/export; Z-domain support for Export single Fault window; LASWriter::doPrepare with log availability checks. - Stability and Reliability Fixes: LASWriter column width safeguards; Geobody stability fixes to prevent crashes and ensure correct iso value flags; tested via volume viewer and iso-value body workflows. - UI Integration and Maintenance: HorizonData selection dialogs and related UI/event plumbing improvements.

Dec 1, 2024December 2024 (OpendTect/OpendTect) focused on stabilizing the platform, accelerating data workflows, and expanding data handling capabilities. Key features delivered include: (1) 2D Seismic Data Loading Performance improvements via multi-threaded geometry reading and optimized lookups; refactoring of sequential CubeData readers to speed processing. (2) UI Table Text Alignment to improve readability and data presentation. (3) Data Handling API Enhancements adding StringPairSet set/getValue and file-based JSON read/write overloads for ValueSet, enabling easier manipulation and persistence of key-value data. (4) HTTP Request Enhancements enabling encoded data support and raw header manipulation with proper Content-Length handling. In parallel, a targeted set of bug fixes improved build stability and runtime correctness, addressing compiler errors, missing headers, mExpClass, a survey copy crash, and SVN path handling during folder rename. Overall impact: faster data processing, more reliable builds, and richer data persistence and HTTP data exchange capabilities. Technologies demonstrated: multi-threading and performance optimization, API design and extension, JSON-based persistence, header-level HTTP control, and UI presentation improvements.

Oct 1, 2024Month: 2024-10 — Focused on stabilizing cross-platform path handling in OpendTect. Implemented a critical bug fix to preserve proper Windows URI path formatting, preventing Windows-specific separators from being appended to URIs in FilePath utilities. The change reduces platform-specific errors in fullPath() and pathOnly(), improving reliability for cross-platform asset references and workflows. This aligns with ongoing portability goals and reduces risk for Windows-based workflows.
