IPointCloudAccess.ReadPoints

Description:
Implement this method so that on successive invocations it will return distinct subsets of points which meet the criterion.

int ReadPoints(
	PointCloudFilter rFilter,
	ElementId viewId,
	IntPtr buffer,
	int nBufferSize
)

Function ReadPoints ( 
	rFilter As PointCloudFilter,
	viewId As ElementId,
	buffer As IntPtr,
	nBufferSize As Integer
) As Integer

int ReadPoints(
	PointCloudFilter^ rFilter, 
	ElementId^ viewId, 
	IntPtr buffer, 
	int nBufferSize
)

abstract ReadPoints : 
        rFilter : PointCloudFilter * 
        viewId : ElementId * 
        buffer : IntPtr * 
        nBufferSize : int -> int

PointCloudFilter

rFilter

The filter used to process cloud points and determine which ones lie with the target volume.
ElementId

viewId

The view id for the current view passed as auxiliary information to allow the engine to optimize retrieval of points. If viewId == InvalidElementId, the query is not for a view display operation.
IntPtr

buffer

Memory buffer into which the points should be written. The buffer was allocated by Revit and it is guaranteed to be valid for the duration of the call.
Int32

nBufferSize

The maximum number of CloudPoint objects that may be copied into the buffer.

Return Value Int32 The actual number of CloudPoint objects placed in the buffer (can be less than the length of the buffer). If there are no points available that match the filter criteria, return 0.
