this code i get on this page https://www.instructables.com/id/Lets-cook-3D-scanner-based-on-Arduino-and-Proces/ because i ve tryed to build a 3d scanner to calculate the volumen of some object

when i compile the code has a error on this line: cam=new GSCapture(this, 640, 480,avcams[0]);

on the serial monitor of prossesing this show me all the cameras but when the code arrive on this line the compilator show me this error on this line cam=new GSCapture(this, 640, 480,avcams[0]);

i dont know why

i have a prossesing version 3.3.6

Please format your code. Edit your post (gear on top right side of any of your posts), select your code and hit ctrl+o. Leaves an empty line above and below your block of code

You should consider checking the examples that come with the video library. In the Processing IDE, go to the menu File>>Examples and then go to libraries>>video>>capture and run any of the code there. You can see that instead of using GSCapture, you could use a Capture object. in any case, running the example would be the first step to check that your hardware is working properly in Processing.
