Class

PVector

Description

Calculates the dot product of two vectors.

Examples

  • PVector  v = new PVector(10, 20, 0);
float d = v.dot(60, 80, 0);
println(d);  // Prints "2200.0"

  • PVector  v1 = new PVector(10, 20, 0);
PVector  v2 = new PVector(60, 80, 0); 
float d = v1.dot(v2);
println(d);  // Prints "2200.0"

Syntax

  • .dot(v)
  • .dot(x, y, z)
  • .dot(v1, v2)

Parameters

  • v(PVector)any variable of type PVector
  • x(float)x component of the vector
  • y(float)y component of the vector
  • z(float)z component of the vector
  • v1(PVector)any variable of type PVector
  • v2(PVector)any variable of type PVector

Return

  • float
