i l try to render a shape and get "vertex(x,y,u,v)is not available with this renderer". I cannot find the mistake. I use version 1.5. The shape rotates, but when i press the mouse button in order to make a pdf of a frame, nothing happens.Can you help?

Thank you

  if (recordPDF) {
    endRaw();
    recordPDF = false;
  }
}

// Make the PDF when the mouse is pressed
void mousePressed() {
  recordPDF = true;
}

I want to make somekind of "screenshots" and export them as PDF, in order to map them in another step on a shape.

here you can see the code of a pattern i made and try to export those frames i choose by Mouse pressed.

It would be great if someone could help! Thank you(i work with processing 1.5)

i would like to exchange the wireframe in this code to a drawing i made with black lines on white surface. I want the white areas to be transparent and only the black ones should appear. Is this possible? How can i do this. I am beginner.

THANK YOU

I´m new in programming and try to make a 3d-shape from a 2d scribble/painting. I use toxiclibs-complete-0020.zip and volumeutils-0003.zip Here is my code i use . Tha  programmer who wrote this code used volumeutils-0004. Maybe thats the problem, that i have a older version-bbut i cannot find the newer version for download ANYWHERE. "Cannot instantiate the type VolumetricSpace" is the error i get by trying using this code. What does it  mean? I work with PC. Thank you a lot!

What I'm doing is writing a sketch which has a white background.  Onto this background, I'll draw in black.  I'll then want to extrude the black areas into a 3d shape(the white will be voids).  I'll then export the 3d shape as a STL and have it 3D printed. How can i extrude only the black areas, in order to form a shape of the black ones?


thank you, Nikolla
