Hi there,

i have a Problem with converting one Array into another.
The Starter Array is a vector Template of a struct, the targetarray is a static float array.
The Array is needed so i have a common array to put into vtkData.

Here the piece of Code:
(Red is the "criticalcode")

Code:
#include <stdio.h>
#include <iostream>
#include <vector>

struct SimpVec
{
  float coordx;
  float coordy;
  float coordz;
};

vector<SimpVec> vecs2;

void pcavis2(vector<SimpVec> vecs2)
{
  cout << "Starting Visualisation" << endl;
  int i;
  static float vecs2f[][3];
  //ExampleArray
  //static float x[3][3]={{0,0.5,0.7}, {0.3,0.9,0.2}, {1,1,1}};
  //Checking if the given Vector has elements
  cout << vecs2.size() << endl;
  //Put Vectordata into a float array
  for (int j=0; j < vecs2.size(); j++){
    vecs2f[i][0] = vecs2[i].coordx;
    vecs2f[i][1] = vecs2[i].coordy;
    vecs2f[i][2] = vecs2[i].coordz;
  };
  //Create testdata and put Scalars and Points into it
  vtkPolyData *testdata = vtkPolyData::New();
  vtkPoints *testpoints = vtkPoints::New();
  vtkFloatArray *testScalars = vtkFloatArray::New();
  for (i=0; i < vecs2.size(); i++) testpoints->InsertPoint(i, vecs2f[i]);
.
.
.
The rest is of the code is plain visualisaion and has no meaning in this Problem.

Thanks in Advance!
Jan
