Class PVector Name sub() Examples PVector v1, v2; void setup() { smooth(); noLoop(); v1 = new PVector(40, 20, 0); v2 = new PVector(65, 70, 0); } void draw() { ellipse(v1.x, v1.y, 12, 12); ellipse(v2.x, v2.y, 12, 12); v2.sub(v1); ellipse(v2.x, v2.y, 24, 24); }PVector v; void setup() { smooth(); noLoop(); v = new PVector(65, 70, 0); } void draw() { ellipse(v.x, v.y, 12, 12); ellipse(40, 20, 12, 12); v.sub(40, 20, 0); ellipse(v.x, v.y, 24, 24); }PVector v1, v2; void setup() { smooth(); noLoop(); v1 = new PVector(65, 70, 0); v2 = new PVector(40, 20, 0); } void draw() { ellipse(v1.x, v1.y, 12, 12); ellipse(v2.x, v2.y, 12, 12); PVector v3 = PVector.sub(v1, v2); ellipse(v3.x, v3.y, 24, 24); } Description Subtracts x, y, and z components from a vector, subtracts one vector from another, or subtracts two independent vectors. The version of the method that substracts two vectors is a static method and returns a PVector, the others have no return value -- they act directly on the vector. See the examples for more context. Syntax vec.sub(x, y, z) vec.sub(v) PVector.sub(v1, v2) Parameters vec any variable of type PVector x float: the x component of the vector y float: the y component of the vector z float: the z component of the vector v PVector: the x, y, and z components of a PVector object v1 PVector: the x, y, and z components of a PVector object v2 PVector: the x, y, and z components of a PVector object vec any variable of type PVector Returns None or PVector Usage Web & Application

Processing was initiated by Ben Fry and Casey Reas. It is developed by a small team of volunteers.
