Jun 1, 2025June 2025 performance summary: Delivered volumetric subject preview and a refactored viewer to enable 3D volumetric data visualization in the subject viewer. Refactored VolumetricViewer into three components (VolumetricFull, VolumetricPreview, VolumetricView) and updated media components and type definitions to support volumetric data visualization. Fixed a critical data integrity bug in machine-learnt reductions by refactoring the useMachineLearntReductions hook to respect toolIndex, ensuring createMark is applied to the correct tool within a task. These workstreams are reflected in commits for traceability (06c8bb5121534073a869dde96cbf446acd56874c: VV added to Subject Preview (#6862); f38d50f504f8e1d6e914d4271c7af945815c7166: Make sure fetched caesar data respects the toolIndex when adding the mark (#6929)). The initiatives collectively enhance analytics reliability, expand data visualization capabilities, and contribute to a modular, maintainable front-end architecture.

Mar 1, 2025Month: 2025-03 — This sprint focused on advancing volumetric data visualization capabilities, improving accessibility, and strengthening privacy, interoperability, and maintainability. Key features delivered include the Volumetric Viewer UI polish with responsive behavior and ARIA improvements for the VV Planes view, the introduction of a VolumetricLayout integrated into the classifier layout system, export alignment for Volumetric Classification to match the FreehandLine tool, privacy-focused filtering to show only the project owner for volumetric projects, and Yarn.lock cleanup to reduce bundle size and vulnerabilities. Major bugs fixed include the color generation limits in Volumetric Viewer to support unlimited annotations and ensuring planar view annotations render when color voxel mappings are removed. Collectively, these changes deliver a more accessible, scalable, and privacy-conscious volumetric workflow, enabling researchers to visualize, annotate, and export volumetric data more reliably. Skills demonstrated include React component architecture, layout system integration, accessibility (ARIA), data model refinement for VolumetricAnnotation, and ongoing dependency hygiene.
