Hello,

rotating a line around the origin:
version B  works fine, A doesn't
(v91/osx)

any thoughts?

thanks,
ana


// VERSION A

void setup() {
 size(400, 400);
 stroke(0,10);
}

float rad = 0.0;

void draw() {
 translate(width/2, width/2);
 rotate(rad);
 line(0, 0, 0, -width/2);
 rad += 0.01;
}


// VERSION B

void setup() {
 size(400, 400, P3D);
 stroke(0,10);
}

float rad = 0.0;

void draw() {
 translate(width/2, width/2);
 rotateZ(rad);
 line(0, 0, 0, -width/2);
 rad += 0.01;
}
