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.w3c.dom.Element; import org.w3c.dom.DOMImplementation; import org.w3c.dom.svg.SVGDocument; import org.apache.batik.swing.JSVGCanvas; import org.apache.batik.svggen.SVGGraphics2D; import org.apache.batik.dom.svg.SVGDOMImplementation; import org.apache.batik.transcoder.TranscoderInput; import org.apache.batik.transcoder.TranscoderOutput; 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 g as if it was the usual canvas */ 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.
