A3DMiscComputeBoundingBox

A3DStatus A3DMiscComputeBoundingBox(const A3DEntity *pEntity, const A3DMiscComputeBoundingBoxOptions *pOptions, A3DBoundingBoxData *pAABB)

A3DStatus A3DMiscComputeBoundingBox(const A3DEntity* pEntity, const A3DMiscComputeBoundingBoxOptions* pOptions, A3DBoundingBoxData* pAABB)

Use the tessellation to compute the axis-aligned bounding box (AABB) of the given entity.

An invalid bounding box corresponds to those values:

• A3DBoundingBoxData::m_sMinis``{1.0, 0.0, 0.0}``
• A3DBoundingBoxData::m_sMaxis``{-1.0, 0.0, 0.0}``

It can occur under following conditions:

• The computation is done on infinite elements.

• The CAD data do not contain any tessellation.

• pEntityis of type:c:type:~A3DRiPlane.

  This function*computes*the bounding box using tessellation data. If you want to read the actual bounding box from CAD data, see:c:func:~A3DMiscGetBoundingBox.

Parameters

pEntity: The Entity to get the bounding box from. It can be any of:c:type:~A3DAsmModelFile,:c:type:~A3DAsmProductOccurrence,:c:type:~A3DAsmPartDefinitionor:c:type:~A3DRiSet.

pOptions: Options of the function. Can be NULL.

pAABB: A pointer to a valid:c:struct:~A3DBoundingBoxDatawhich will be filled in with the computed bounding box. If not possible an invalid bounding box is filled in (see below).

Returns

A3D_SUCCESSon success, or an error code on failure
