The basis vectors defining the local coordinate system, stored as a flat 9-element array in column-major format: [ x0, x1, x2, y0, y1, y2, z0, z1, z2 ] Each axis should be a normalized vector.
The origin of the coordinate system in global space.
OptionalscaleOptional: a multiplier to convert units into meters.
If not specified, a default will be assumed based on the units field.
Example: 0.3048 for feet, 0.001 for millimeters.
The unit of measurement used in coordinates. This is required to interpret distances and scales correctly.
Describes the coordinate system, origin, and unit system in which a 3D model was authored. This provides the spatial context necessary to correctly interpret and transform model geometry into a common viewer space.
