What's New in 1.2.0 LiDAR Mesh Reconstruction & Occlusion - Trajectories now hide behind real-world objects (walls, furniture) using LiDAR mesh as invisible occluder - Accurate surface normals on curved surfaces (e.g. cylindrical objects) for precise impact angle calculation - New "Show Mesh" toggle to visualize the reconstructed 3D surface Improved Detection & Accuracy - Fixed tail direction detection: axes now correctly point toward the area of origin - Automatic drop diameter estimation from perspective-corrected minor axis measurement — no manual input needed - Angle confidence indicator in live overlay (checkmark / warning) - Ghost lines: classic 2D convergence lines projected on the surface Better Interaction - Professional crosshair design with corner brackets and center dot - Tap on a trace to select it, then remove with a dedicated button - Undo last axis button for quick corrections - Show/Hide axes toggle — see only trajectories and convergence by default - Axis label shows impact angle and measured drop diameter Stability & Performance - Numerical fixes: quaternion rotation, cubic solver, CLAHE histogram, perspective correction guards - Eliminated per-frame scene graph enumeration — direct node references - Throttled mesh updates and tracking indicator - Warnings for fewer than 3 axes and micro-droplets
