No normals when I use this in my own class
Hi, sorry to bother you, especailly on such an old (but very useful) repo. I am trying to use this to create a tube in my own code and face a strange issue. I am basing my experiments on your example-circle-points, I am getting my points from a polyline, using an addon that lets me draw curves, https://github.com/fred-dev/ofxBezierEditor.
I was going a bit crazy as when I use your addon within the ofxBezierEditor class, when I try to draw the tube with normals I get the error that the mesh does not have normals enabled. I checked your build() method and it explicity turns on normals. After some efforts at understanding this, I instead included your addon in my ofApp.h file, extracted my polyline from the above addon and then used the points in a ofxBranchesPrimitive instance inside ofApp, and the normals are enabled and draw as expected.
Do you know by any chance what would casue this issue - there doesnt seem to be a way to not have normals with your addon ofxBranchesPrimitive::build(), as inside the method it calls getMesh().enableNormals(); The only functional difference is that the ofxBranchesPrimitive instance is inside the ofApp.h class, not in my class that is itslef included in ofApp.h.
cheers
