what is that identity - an array of points or an SVG-file?

here the library peasycam is used, you can thus direct the camera in 3D with the mouse

in processing hit
ctrl and ,

you get the options

first line tells you the folder dor your sketches

create a folder libraries there and PeasyCam inside

like
D:\docs..........\Processing\libraries\peasycam
