Copy

public void GetRgbaValues(
	IList<SbVec4ub> rgbaValues,
	IList<SbVec3f> objectPos,
	IList<SbVec3i32> dataPos,
	IList<SoLDMTileID> tileIds,

Public Sub GetRgbaValues ( 
	rgbaValues As IList(Of SbVec4ub),
	objectPos As IList(Of SbVec3f),
	dataPos As IList(Of SbVec3i32),
	tileIds As IList(Of SoLDMTileID),

public:
void GetRgbaValues(
	IList<SbVec4ub>^ rgbaValues, 
	IList<SbVec3f>^ objectPos, 
	IList<SbVec3i32>^ dataPos, 
	IList<SoLDMTileID>^ tileIds, 
	float opacityThreshold

member GetRgbaValues : 
        rgbaValues : IList<SbVec4ub> * 
        objectPos : IList<SbVec3f> * 
        dataPos : IList<SbVec3i32> * 
        tileIds : IList<SoLDMTileID> * 
        opacityThreshold : float32 -> unit

Parameters

rgbaValues: Type: System.Collections.GenericIListSbVec4ub
objectPos: Type: System.Collections.GenericIListSbVec3f
dataPos: Type: System.Collections.GenericIListSbVec3i32
tileIds: Type: System.Collections.GenericIListSoLDMTileID
opacityThreshold: Type: SystemSingle

Remarks

Voxels with a alpha value less or equal to opacityThreshold are ignored. Values returned are based on the (possibly subsampled) tiles currently in memory.
