function addTriangle(x, y, z, w, h) {
this.addLine(x, y, z,
x + w/2, y, z,
x, y - h, z,
x- w/2, y, z,
x, y, z);
}
perfection!! no matter how wide the line. Instead of drawing the triangle from 3 points (left, right, top) I am using 4 – mid to right, right to top, top to left, left to mid.
Thanks to Lori for just lying there girggling while I got this down!!
