Hello,
Texturing a QUAD:
PShape qd;
PImage img;
void setup()
{
size(200, 200, P2D);
img = loadImage("https://cdn.theatlantic.com/thumbor/jb3UdKqcmt1JleWOqNj8UWRxcFk=/0x591:2832x2184/976x549/media/img/mt/2017/10/Pict1_Ursinia_calendulifolia/original.jpg");
qd = createShape(QUAD, 50, 50, 170, 70, 150, 150, 30, 170);
qd.setTexture(img);
shape(qd, 0, 0);
noLoop();
}
