[vtkusers] vtkOpenGLOffscreenRenderWindow + vtkTexture = bus error

[Mykola Khotyaintsev]

Dear John/VTK users,

vtkOpenGLOffscreenRenderWindow works good if I don't use any texture. If
I set the texture - the programm crashes with the BUS ERROR while
executing renWin.Render() :( 

	Please help.


Here is the example code:

import vtk.*;
import java.awt.*;
import java.awt.event.*;

public class offscreen {

public static void main (String[] args)
{

  System.loadLibrary("vtkJava");
  
  vtkOpenGLOffscreenRenderWindow renWin = new 
vtkOpenGLOffscreenRenderWindow();
  
  vtkRenderer ren = new vtkRenderer();
  
  renWin.SetSize(400, 400);
  
  renWin.AddRenderer(ren);
  
  vtkSphereSource sphere = new vtkSphereSource();
  	sphere.SetRadius(1.0);
  	sphere.SetThetaResolution(18);
  	sphere.SetPhiResolution(18);

  vtkPolyDataMapper map = new vtkPolyDataMapper();
  	map.SetInput(sphere.GetOutput());
  	map.ImmediateModeRenderingOn();
	
  vtkTexture atext = new vtkTexture();
  vtkPNMReader pnmReader = new vtkPNMReader();
	pnmReader.SetFileName("/home/ko/ovt2g/images/earth_grid.pnm");
	atext.SetInput(pnmReader.GetOutput());
	atext.InterpolateOn();
	
  vtkActor aSphere = new vtkActor();
  	aSphere.SetMapper(map);
	aSphere.SetTexture(atext);
	

  ren.AddActor(aSphere);
  ren.SetBackground(1,1,1); // Background color white

  System.out.print("Rendering ... ");
  renWin.Render();
  System.out.println("done.");  

  
  vtkWindowToImageFilter windowToImageFilter = new
vtkWindowToImageFilter();
  	windowToImageFilter.SetInput(renWin);
	
  vtkPNMWriter writer = new vtkPNMWriter();		
	writer.SetInput(windowToImageFilter.GetOutput());
  	writer.SetFileName("earth.ppm");
	writer.Write();
}

}

Here is the error message:
