I am experiencing an out-of-memory error when using RealitySolutionsSDK_v24.0.1 to read an RCP file that contains unstructured scans of over 7 billion points. The issue occurs during point iteration using the RCPointIterator, even when running the sample code provided in the SDK documentation (RCPReaderSample).
Environment:
SDK Version: RealitySolutionsSDK_v24.0.1
Sample Code: RCPReaderSample from SDK examples
Operating System: Windows 10
Steps to Reproduce:
Load an RCP file containing unstructured scans with over 7 billion points using the RCPReaderSample code. Using the following code snippet to iterate over the points, I removed the write to file from the sample:
RCPointIteratorSettings settings;
settings.setDensity(pointDensity);
settings.setIsVisiblePointsOnly(visiblePointsOnly);
auto totalPoints = 0u;
auto pointIterator = project->createPointIterator(settings);
while (pointIterator->moveToNextPoint())
{
totalPoints++;
}
Run the application and monitor memory usage.
Expected Behavior:
The application should efficiently iterate over all points without exhausting system memory, regardless of the point cloud size.
Actual Behavior:
The application continuously consumes memory during iteration until it eventually runs out of memory and crashes.
Additional Information:
The issue occurs even when using the sample code provided with the SDK, suggesting it is not specific to my implementation. The problem seems to be exacerbated with large, unstructured point clouds. No exceptions or error messages are provided before the crash; the application simply runs out of memory.
Any guidance on workarounds or fixes would be greatly appreciated.
