SoLDMDataAccess.GetData Method (SoLDMDataAccess.DataInfoPolyLine, Int32, SbBox3i32, SbVec3i32[], SoBufferObject)

Given a subvolume in voxel coordinates and a polyline (set of connected line segments), copies the data intersecting each line segment with the subvolume into an application buffer.

Syntax

C++

Copy

public void GetData(
	SoLDMDataAccessDataInfoPolyLine infoPolyline,
	int resolution,
	SbBox3i32 subVolume,
	SbVec3i32[] polyline,
	SoBufferObject bufferObj
)

Public Sub GetData ( 
	infoPolyline As SoLDMDataAccessDataInfoPolyLine,
	resolution As Integer,
	subVolume As SbBox3i32,
	polyline As SbVec3i32(),
	bufferObj As SoBufferObject
)

public:
void GetData(
	SoLDMDataAccessDataInfoPolyLine^ infoPolyline, 
	int resolution, 
	SbBox3i32 subVolume, 
	array<SbVec3i32>^ polyline, 
	SoBufferObject^ bufferObj
)

member GetData : 
        infoPolyline : SoLDMDataAccessDataInfoPolyLine * 
        resolution : int * 
        subVolume : SbBox3i32 * 
        polyline : SbVec3i32[] * 
        bufferObj : SoBufferObject -> unit

Parameters

infoPolyline: Type: OIV.LDMSoLDMDataAccessDataInfoPolyLine
resolution: Type: SystemInt32
subVolume: Type: OIV.InventorSbBox3i32
polyline: Type: OIV.InventorSbVec3i32
bufferObj: Type: OIV.Inventor.DevicesSoBufferObject

Remarks

The resolution is the power of 2 of the desired subsampling level (0:1/1, 1:1/2, 2:1/4, ...) NOTE: The data is copied.

All information is returned in the struct DataInfoPolyline. Call this method with buffer = NULL to get the required size of the application buffer (in the bufferSize member of OIV.LDM.SoLDMDataAccess.DataInfoLine).
