Description

This example illustrates how to use the DotProduct method to obtain the scalar product between two 3D vectors.

Code

#include <tchar.h>
#include <stdio.h>
#include <system.types.hpp>

int _tmain(int argc, _TCHAR* argv[])
{
	float aValue;

	TVector3D *aVector1=new TVector3D(1,2,3,1);
	printf("%2.2f %2.2f %2.2f\n",aVector1->X,aVector1->Y,aVector1->Z);
	// The console will output: 1.00 2.00 3.00, representing the coordinates for aVector1.

	TVector3D *aVector2= new TVector3D(45,7,1,1);
	printf("%2.2f %2.2f %2.2f\n",aVector2->X,aVector2->Y,aVector2->Z);
	// The console will output: 45.00 7.00 1.00, representing the coordinates for aVector2.

	aValue=aVector1->DotProduct(*aVector2);
	printf("%2.2f", aValue);
	// The console will output: 62.00, representing the scalar product between aVector1 and aVector2.

	return 0;
}
