My personal homepage proper is at http://cs.nott.ac.uk/~jxm. This is just SAGE Days related stuff:

Compiling VTK:

Even the latest stable version of VTK (5.0.4) makes some weird assumptions about namespaces. In order to make it compile with GCC 4.3, replace #include <string> with #include <string.h> and similarly for other C library headers.

Using Java VTK Wrappers:

Add vtk.jar to your classpath. Notice the jar file can end up in a fresh /VTK-build/, even though you have specified other build output directory.
Add the directory where libvtkRenderingJava.so resides to your path (export to PATH seems to work just as well as -Djava.library.path=~/VTK-build/bin/ at java's command line)
Add libmawt.so to you LD_LIBRARY_PATH in your environment (export seems to work, although -DLD_LIBRARY_PATH at java's command line does not)

SVG and PDF Output for JyScript.

This should be a quick hack using Apache Batik (http://xmlgraphics.apache.org/batik/). Replace the standard Graphics2D with the Graphics2D from Batik to get SVG export.

import org.apache.fop.svg.PDFTranscoder;

public class Demo extends Applet {

 /* ... */ 

 public static void export() {
   DOMImplementation impl = SVGDOMImplementation.getDOMImplementation();
   String svgNS = SVGDOMImplementation.SVG_NAMESPACE_URI;
   SVGDocument doc = (SVGDocument)impl.createDocument(svgNS, "svg", null);
   SVGGraphics2D g = new SVGGraphics2D(doc); 

   /* Here use can use g as if it was the usual canvas */ 

   /* Here we make it visible */ 

   Element root = doc.getDocumentElement(); 
   g.getRoot(root); 
   JSVGCanvas canvas = new JSVGCanvas();
   JFrame f = new JFrame();
   f.getContentPane().add(canvas);
   canvas.setSVGDocument(doc);
   f.pack();
   f.setVisible(true);

   /* Here we produce the PDF */

   try {
     PDFTranscoder pdfTranscoder = new PDFTranscoder();
     TranscoderInput tIn = new TranscoderInput(doc);
     FileOutputStream fileOut = new FileOutputStream("test.pdf");
     TranscoderOutput tOut = new TranscoderOutput(fileOut); pdfTranscoder.transcode(tIn, tOut); fileOut.flush(); fileOut.close();
    } catch(Exception e) {e.printStackTrace();}

 }

TeX and PS and PDF Output for SAGE plot3s

This could perhaps be done using Sketch (http://www.frontiernet.net/~eugene.ressler/). It implements the painter's algorithm (z-buffering), and hence it should be just the output of triangles in the right format it takes.
