PROFILE
Amir Tadros
Amir Meyers contributed to the BabylonJS/Babylon.js repository by engineering features and fixes that improved 3D graphics workflows and editor tooling. He enhanced scene graph robustness, expanded dynamic geometry support, and delivered safer camera controls for orthographic projection. His work included refining camera zoom logic, propagating detailed drag event data for gizmo interactions, and broadening API compatibility with immutable matrix types. Using TypeScript, JavaScript, and advanced math, Amir addressed edge cases in geometry and coordinate systems, improved maintainability, and enabled more granular editor experiences. His systematic approach resulted in reliable, extensible solutions that strengthened both runtime stability and developer experience.

Aug 1, 2025Month: 2025-08 — Focused on enhancing drag interactions within Babylon.js editor tooling by propagating gizmo drag observer data to gizmos and exposing detailed drag event data and observer information during drag operations. Implemented via two commits: 7dffdaa4be03bf23210192ff3b4266ccb1cdbb05 (Pass through gizmo drag observer messages (#17055)) and 75d87dc3c63047502bb125c933616a2629ae83fa (Pass through eventState with eventData (#17073)). This enables pointer details and eventData to be available at the gizmo level, supporting more granular control and richer editor interactions. No major bug fixes this month; effort focused on feature enhancement and integration to improve editing UX. Overall, this work strengthens the Babylon.js tooling surface, enabling more precise and customizable drag experiences for users and add-on developers.

Jun 1, 2025June 2025 focused on delivering robust camera controls for the Babylon.js orthographic mode. The primary achievement was delivering the ArcRotateCamera ZoomOn enhancement, which updates both the camera radius and the orthographic extents (left/right/top/bottom) proportionally during zoom to maintain correct aspect ratio and view frustum. This work improves precision, consistency, and UX for scenes using orthographic projection, and reduces edge cases where zoom would distort the view. The work was implemented in the BabylonJS/Babylon.js repository, with a targeted commit adding support for zoomOn with ArcRotateCamera in Orthographic mode (#16737).

May 1, 2025May 2025: Babylon.js project contributions focused on API safety, correctness, and developer experience. Key features delivered include an internal API improvement to bakeTransformIntoVertices so it accepts DeepImmutable<Matrix>, broadening type compatibility with immutable matrices while preserving existing behavior. A major bug fix was implemented for the rotation gizmo in right-handed coordinate systems, inverting the rotation angle sign in the fragment shader to correct shading and improve visual accuracy. These changes enhance API safety and developer UX, enabling safer integrations and more reliable 3D tooling. Technologies demonstrated include TypeScript type-level improvements with DeepImmutable, matrix handling, and shader/coordinate-system logic. Commit references: 477e3bc53df756332d394f50477a917779dbe11d (Let Mesh.bakeTransformIntoVertices use DeepImmutable<Matrix>), 46e2a04d5a76b5f60debed90b52479969aa2822a (Fix rotation gizmo fragment shader angle when using right handed system).

Jan 1, 2025January 2025: Focused on reinforcing scene graph robustness and expanding dynamic geometry capabilities in Babylon.js. Delivered a safety fix for TransformNode removal to prevent unintended parent-child mutations, and added zero-dimension plane support to PlaneBuilder for dynamic, explicit plane geometries. These changes reduce runtime risks, enable new use cases, and demonstrate solid code quality and maintainability across the core repo.
