- Use this template for creating your Moving Poster
- Take care that your work appears correctly at different resolutions
- Avoid editing the OpenCV and setupScreen files
- You may need to adjust the lighting situation for the face tracking to work correctly
Tips for optimising Performance:
- Printing to the console is quite slow. Be sure to comment any print() and println() cals in your code before presenting.
- Optimise any graphic and videos so they are no bigger that absolutely necessary.
- Resizing images in real time is very slow. You can speed this up by resizing any images at the program start. See the example below.
- As a last resort, we can reduce the monitor resolution to speed things up

PImage bg;
void setup() {
size(640, 360);
bg = loadImage("image.jpg");
bg.resize(width,height); // we rescale the image once here, instead of in the draw loop
}
void draw() {
image(bg, 0, 0);
// this is much faster than image.(bg, 0,0, width, height) which would rescales the graphics every frame
}

For exporting images the folowing code can be used (PDF doesn't work with 3D for example) :

language | java |

void setup() {
size(2100,2970,P3D);
}
void draw() {
//code for exporting image on each frame
save("export/frame"+frameCount+".png");
if (frameCount == 30) {
exit();
}
