.. _struct_NORMAL_VECTOR:

NORMAL_VECTOR
==============

This structure defines the **normal vector calculation data** used for  
computing surface or orientation normals based on multiple reference poses.  
It stores three vector components, each containing six floating-point elements  
representing positions or directions in 3D space.
