SAFETY_ZONE_SHAPE_DATA

This union defines a flexible data container for multiple safety zone shape types, allowing a single structure to represent spheres, cylinders, cuboids, capsules, or other complex 3D zone geometries. It is used in conjunction with zone configuration structures (e.g., CONFIG_SAFETY_ZONE).

The union ensures efficient memory use by sharing a single data block across different shape definitions.

BYTE#	Field Name	Data Type	Shape Type	Remarks
0	_tSphere	SAFETY_ZONE_SHAPE_SPHERE	Sphere	Defines a spherical zone using center and radius.
0	_tCylinder	SAFETY_ZONE_SHAPE_CYLINDER	Cylinder	Defines a cylindrical zone with radius and Z-limits.
0	_tCuboid	SAFETY_ZONE_SHAPE_CUBOID	Cuboid	Defines a rectangular box aligned with global axes.
0	_tOBB	SAFETY_ZONE_SHAPE_TILTED_CUBOID	Tilted Cuboid	Defines an oriented (rotated) box using local axes.
0	_tMultiPlane	SAFETY_ZONE_SHAPE_MULTI_PLANE	Multi-Plane	Defines a convex volume bounded by up to six planar surfaces.
0	_tCapsule	SAFETY_ZONE_SHAPE_CAPSULE	Capsule	Defines a capsule zone (cylinder with hemispherical ends).
0	_iBuffer	unsigned char[120]	Raw memory buffer	Used for unified memory mapping across all shape types.

Total size: 120 bytes (maximum shared buffer)

Note

• This union enables a polymorphic representation of safety zone shapes.

• Only one shape field is valid at a time depending on the selected zone type.

• _iBuffer serves as the raw binary memory region for data serialization or protocol transmission.
