sub3 static method
Subtract one vector from another and store in another vector @param target PVector in which to store the result
Implementation
static PVector? sub3(PVector v1, PVector v2, PVector? target) {
if (target == null) {
target = new PVector(v1.x - v2.x, v1.y - v2.y, v1.z - v2.z);
} else {
target.set(v1.x - v2.x, v1.y - v2.y, v1.z - v2.z);
}
return target;
}
