Overview
The SetBoundingBox method sets the bounding box information in a mesh object, defining the spatial extent of the mesh. It has two versions: one accepting a BoundingBox_ object, and another calculating the bounding box from node coordinates.
Syntax
! Version 1: From BoundingBox_ object
CALL obj%SetBoundingBox(box)
! Version 2: From node coordinates
CALL obj%SetBoundingBox(nodes, local_nptrs)
Parameters
Version 1
| Parameter | Type | Intent | Description |
|---|---|---|---|
obj | CLASS(AbstractMesh_) | INOUT | The mesh object |
box | TYPE(BoundingBox_) | IN | The bounding box to set for the mesh |
Version 2
| Parameter | Type | Intent | Description |
|---|---|---|---|
obj | CLASS(AbstractMesh_) | INOUT | The mesh object |
nodes | REAL(DFP)(:,:) | IN | Node coordinates in XiJ format |
local_nptrs | INTEGER(I4B)(:) | IN (optional) | Local to global node number mapping |
Description
SetBoundingBox updates the bounding box information in the mesh object. This information is used for various mesh operations, including domain decomposition, visualization, and spatial queries.
Version 1 directly sets the bounding box from a BoundingBox_ object, while Version 2 calculates the bounding box from node coordinates, optionally using a node mapping.
Implementation Notes
Version 1 extracts the min/max coordinates from the provided bounding box using operators like .Xmin., .Ymin., etc.
Version 2 calls GetBoundingBox to calculate the bounding box from node coordinates, then calls Version 1 to set it.
