Using rotateAroundDeg

beginners
#1

I am trying to rotate a 3d cylinder by 90 degrees but cannot find how. Can anyone give me an example on how to use rotateAroundDeg to do this?

Many thanks

Hi @vestus,

I think if you try to use something like ofRotateXDeg, it should work.

So assuming you have an cylinder, you can write something like this:
in ofApp.cpp::draw()

    ofCylinderPrimitive cylinder;
    cylinder.set(10, 2.2);
    ofPushMatrix();
    ofRotateXDeg(90);
    cylinder.draw(200,290);
    ofPopMatrix();

It’s best practice to use ofPushMatrix() and ofPopMatrix(), as the transformation will only apply to what’s inbetween them.

Hope this helps,
