Detailed Description

Function Documentation

crossProduct()

sf::Vector3f crossProduct	(	sf::Vector3f	a,
		sf::Vector3f	b )

cross product of two vectors gives you a new vector that is perpendicular to both input vectors

Parameters

a
b

Returns

sf::Vector3f

dotProduct()

float dotProduct	(	sf::Vector3f	a,
		sf::Vector3f	b )

give an idea about how much two vectors are aligned

• If the dot product is positive, the vectors point in roughly the same direction.
• If the dot product is zero, the vectors are perpendicular (at a 90° angle to each other).
• If the dot product is negative, the vectors point in opposite directions.

need to normalize the vectors before using the dot product

Parameters

a
b

Returns

float
