Bugfixes

  • Point cloud profile rendering fix — fixed RGBA attribute numElements calculation that prevented profile display

Units Support

  • Flexible units configuration — independent settings for coordinates (m/ft/in) and display measurements (m/ft/in), allowing any combination (e.g., coordinates in feet, measurements in meters)
