How would i rotate a path around a specific point?

beginners
#1

I’m trying to make a path rotate spin clockwise in the center of the screen. but the axes used by the rotate function is centered on the top left of the screen. currently my solution is this

void ofApp::update(){
    mainPath.translate(ofVec2f(-1*center.x,-1*center.y));//center is just a vector containing the center coords
    mainPath.rotateDeg(1,ofVec3f(0,0,1));
    mainPath.translate(center);
}

is there a different way of doing this without moving the path to 0,0. preferably changing where 0,0 is located?

if the path is used always like this I would suggest you have the (0, 0) point in the center of your path.
to do this you use this on setup once

mainPath.translate(ofVec2f(-1*center.x,-1*center.y));

in update just this one

    mainPath.rotateDeg(1,ofVec3f(0,0,1));

and you can use

ofTranslate(center);

on draw

hi, you can do that or use ofRotate and ofTranslate which is more or less the same but it will not actuallty move the points of the path but rather rotate the whole scene in open GL, which is way much more eficient.
