Hi, I'm trying to program a surface with opengl evaluators or glunurbs, but this two functions needs a multidimensional array (three dimension) for points. I have my points in three Qvector (one for x, one for y and one for z). When I trying to convert this qvectors to a array i have an error, but i dont know what. The compiler says ok all, but when i run the program, the program exit with no warning. This is the code:
Qt Code: 
  1. GLuint GLWidget::makeSurf(const GLfloat *reflectance,QVector<float> x,QVector<float> y,QVector<float> z)
  2. {
  3. 	float ***points;
  4. 	int dimx=x.size();
  5. 	int dimy=y.size();
  6.  
  7. 	points= new float **[dimx];
  8. 	for (int i=0;i<dimx;i++){
  9. 		points[i]=new float *[dimy];
  10. 		for (int j=0;j<dimy;j++){
  11. 			points[i][j]=new float[3];
  12. 		}
  13. 	}
  14. 	int cont=0;
  15. 	for (int ix=0; ix<dimx; ix++){
  16. 		for (int iy=0; iy<dimy; iy++){
  17. 			cont++;
  18. 			points[ix][iy][0]=x[cont];
  19. 			points[ix][iy][1]=y[cont];
  20. 			points[ix][iy][2]=z[cont];
  21. 		}
  22. 	}
  23.  
  24.  
  25.       or this way:
  26.  
  27.         points = new float **[dimx];
  28. 	for(int i=0;i<dimx;i++)	{
  29. 		*(points+i) = new float *[dimy];
  30. 	 	for(int j=0;j<dimy;j++){
  31. 			*(*(points+i)+j) = new float[3];
  32. 		}
  33. 	}
  34. 	int cont=0;
  35. 	for(int i=0;i<dimx;i++)	{
  36. 		for(int j=0;j<dimy;j++)	{
  37. 			*(*(*(points+i)+j)+0) = x[cont];
  38. 			*(*(*(points+i)+j)+1) = y[cont];
  39. 			*(*(*(points+i)+j)+2) = z[cont];
  40. 			cont++;
  41. 		}
  42. 	}
  43. ..........
  44. }

Both samples crash. I have check dimension of qvectors and are ok. But exit the programm with no warning.
Need help please.
Thanks
