4.3.1.24. NXgeometry¶
Status:
base class, extends NXobject
DEPRECATED: as decided at 2014 NIAC meeting, convert to use NXtransformations
Description:
legacy class - recommend to use NXtransformations now
It is recommended that instances of NXgeometry be converted to use NXtransformations.
This is the description for a general position of a component. It is recommended to name an instance of NXgeometry as “geometry” to aid in the use of the definition in simulation codes such as McStas. Also, in HDF, linked items must share the same name. However, it might not be possible or practical in all situations.
Symbols:
No symbol table
- Groups cited:
Structure:
@default: (optional) NX_CHAR
Declares which child group contains a path leading to a NXdata group.
It is recommended (as of NIAC2014) to use this attribute to help define the path to the default dataset to be plotted. See https://www.nexusformat.org/2014_How_to_find_default_data.html for a summary of the discussion.
description: (optional) NX_CHAR
Optional description/label. Probably only present if we are an additional reference point for components rather than the location of a real component.
component_index: (optional) NX_INT
Position of the component along the beam path. The sample is at 0, components upstream have negative component_index, components downstream have positive component_index.
SHAPE: (optional) NXshape
shape/size information of component
TRANSLATION: (optional) NXtranslation
translation of component
ORIENTATION: (optional) NXorientation
orientation of component
