Fonts in 3d for PDF export
May 10th, 2006, 3:44pm  
Hi,

I'm making a 3d graph with processing and want to add labels to the axes.  The whole graph is rotated to an isometric view for prettiness and when using P3D to screen, I can write the axis labels no problem.  

However if I try to write it out to PDF, the fonts just come out as big black blocks.  Any ideas?  Here's the relevant bit of code:

Code:

import processing.pdf.*;
PGraphics pdf;
PFont font;

void setup() {  

  size(1000, 1000, P3D);  
  font = createFont("TW Cen MT",32);
  textFont(font);
  pdf = createGraphics(PDF, "landscape.pdf");
}  

void draw() {

  beginRaw(pdf);
  // translating and rotating and drawing stuff...
  text("Test",xDist/3,yDist,0);
  endRaw();
  exit();}
}


Thanks for your help!

the only way to do it (this will improve later) is to use some undocumented features Smiley

1) you have to use the OPENGL renderer
2) use textMode(SHAPE);
3) use createFont() (which you already are)

this will convert all the shape data from the fonts for writing. it will be *extremely* slow, which is part of why it's not documented yet. but it will work with beginRaw().
