[pdal] One last follow up.

[David Serret Mayer]

Hey there!

Hopefully this will be my last question, let see if I can finally get it
right.
I tried today to use the Pipeline manager as recommended. But I cant figure
out how to make it work with an reader.buffer type as input.

If I put the JSON like this:
{
  "pipeline":[
    {
      "type":"readers.buffer"
    },
    {
      "type":"filters.chipper",
      "capacity":"400"
    },
    {
      "type":"writers.pgpointcloud",
      "connection":"dbname='lidar' user='user'"
    }
  ]
}

I get the error:  Couldn't create reader stage of type 'readers.buffer'.


If I stage the buffer as seen on SmoothKernel.cpp y get the same error.
....
    PipelineManager mgr;
    mgr.readPipeline("../p.json");


        BufferReader& bufferReader =
                dynamic_cast<BufferReader&>(mgr.makeReader("",
"readers.buffer"));
                        bufferReader.addView(view);
      mgr.prepare();
    mgr.execute();
....

This is the program I am working on right now:

#include <pdal/filters/ChipperFilter.hpp>
#include <io/BufferReader.hpp>
#include <io/BufferReader.hpp>

#include <pdal/Kernel.hpp>
#include <pdal/pdal_export.hpp>
#include <pdal/util/FileUtils.hpp>

#include<pdal/PipelineReaderJSON.hpp>
//#include <pdal/plugins/pgpointcloud/io/PgCommon.hpp">

#include <memory>
#include <vector>

#include <pdal/PDALUtils.hpp>
#include <pdal/StageFactory.hpp>
#include <pdal/PipelineExecutor.hpp>
#include <pdal/util/FileUtils.hpp>

void fillView(pdal::PointViewPtr view)
{
    struct Point
    {
        double x;
        double y;
        double z;
    };

    for (float i = 0; i < 10000; i += 1.0)
    {
        Point p;

        p.x = -93.0 + i*0.00000001*i;
        p.y = 42.0 + i*0.00001*i*i;
        p.z = 106.0 + i;

        view->setField(pdal::Dimension::Id::X, i, p.x);
        view->setField(pdal::Dimension::Id::Y, i, p.y);
        view->setField(pdal::Dimension::Id::Z, i, p.z);
    }
}


int main()
{
    using namespace pdal;


    PointTable table;
    table.layout()->registerDim(Dimension::Id::X);
    table.layout()->registerDim(Dimension::Id::Y);
    table.layout()->registerDim(Dimension::Id::Z);

    PointViewPtr view(new PointView(table));
    fillView(view);
    BufferReader r;
    r.addView(view);


    PipelineManager mgr;
    mgr.readPipeline("../p.json");


    mgr.prepare();
    mgr.execute();
}

p.json is:

{
  "pipeline":[
    {"type":"readers.buffer"           <-wrong
    },
    {
      "type":"filters.chipper",
      "capacity":"400"
    },
    {
      "type":"writers.pgpointcloud",
      "connection":"dbname='lidar' user='user'"
    }
  ]
}

Again, thanks in advance for your help.
