20 Scaling Vectors
Q3Vector2D_Scale
function to scale a two-dimensional vector.
TQ3Vector2D *Q3Vector2D_Scale ( const TQ3Vector2D *vector2D, float scalar, TQ3Vector2D *result);vector2D
A two-dimensional vector.scalar
A floating-point number.result
On exit, a two-dimensional vector that is the result of multiplying each of the components ofvector2D
by the value of thescalar
parameter.
Q3Vector2D_Scale
function returns, as its function result and in the result
parameter, the two-dimensional vector that is the result of multiplying each of the components of the vector vector2D
by the value of the scalar
parameter. Note that on entry the result
parameter can be the same as the vector2D
parameter.
