Hey John, just came across this, phenomenal work.

Hi John, I am not sure if you would be checking new remarks on this page, but I am giving it a try. I am trying to use your code from this link (http://gracefulspoon.com/processingapps/singlewave/waveform_landscape04.pde) and after downloading the rar file with .pde and .mp3, everything is working except ‘record’ facility. I am using Processing version 3 on an 2011 iMac, and when I press the ‘r’ key, processing interface freezes with the following issue highlighted in red: RawDXF can only be used with beginRaw(), because it only supports lines and triangles. Line 170 – endShape(CLOSE) is also highlighted in yellow.

Any help in recording the DXF will be highly appreciated!
thank you much!

HI JOHN,

I’VE DOWNLOADED PROCESSING 1.5 ON A WINDOWS COMPUTER AND THE CODE I RUNNING, HOWEVER IT DOESNT SEEM TO RECORD THE WHOLE THING WHEN I PRESS ‘r’

Thanks for your prompt reply! I’ve tried using Processing 1.5 however the application can’t seem to open up on my mac. This may be a little out of your expertise

Use processing 1.5

Hi John!

I have the same problem when trying to record. It says ‘RawDXF can only be used with beginRaw()’. I tried downloading your rar. file but it made no difference. Im using Processing 3 on a Mac. Please help!

The solution to the ‘rawDXF can only be used with beginRAW(), because it only supports lines and triangles’ issue is to simply reverting back to processing 1.5.

In 1.5 – everything works like a charm!

Hi John,

Amazing work- thanks for posting! I am running into exactly the same issue as bernardo above – would you happen to know what might the issue be?

Best,

hello john,
thank you for posting this, great job. I was able to load an audio file of my own but I’m running into trouble when trying to export the DXF file. A warning pops up in processing ‘rawDXF can only be used with beginRAW(), because it only supports lines and triangles’ and then the sketch crashes. A file does appear in the sketch’s folder but when I try to open it with rhino all i get is a tiny bit of the waveform. I’m using processing 3.
best,
bernardo
