EpsilonEquals (SIQuaternion)

Description

Tests the equality between this quaternion and the quaternion q with a tolerance of epsilon.

Scripting Syntax

SIQuaternion.EpsilonEquals( epsilon )

C# Syntax

Int32 SIQuaternion.EpsilonEquals( SIQuaternion in_pQuat, Double in_dEpsilon );

Parameters

Return Value

Boolean True if this quaternion equals the quaternion q; otherwise False.

Examples

JScript Example

/*
   This example demonstrates how to test whether the values of two
   quaternions are within 0.002 of each other using the EpsilonEquals method
*/
var q1 = XSIMath.CreateQuaternion(1.0, 1.0, 2.0, 3.0);
var q2 = XSIMath.CreateQuaternion(1.0, 1.001, 2.0, 3.0);
var q3 = XSIMath.CreateQuaternion(1.0, 1.003, 2.0, 3.0);

// Equal by less than 0.002
ValidateEpsilonEquals(q1, q2);

// Not equal by less than 0.002
ValidateEpsilonEquals(q1, q3);

function ValidateEpsilonEquals (in_q1 , in_q2)
{
   if ( in_q1.EpsilonEquals(in_q2, 0.002) ) {
       Application.LogMessage ("in_q1 is equal to in_q2 by less than 0.002");
   } else {
       Application.LogMessage ("in_q1 is not equal to in_q2 by less than 0.002");
   }
}

// Expected results:
// INFO : in_q1 is equal to in_q2 by less than 0.002
// INFO : in_q1 is not equal to in_q2 by less than 0.002
