Q3Vector3D_Set

You can use the Q3Vector3D_Set function to set the scalar components of a three-dimensional vector.

TQ3Vector3D *Q3Vector3D_Set (
TQ3Vector3D *vector3D, 
float x, 
float y, 
float z);

vector3D

A three-dimensional vector.

x

The x scalar component of the vector.

y

The y scalar component of the vector.

z

The z scalar component of the vector.

DESCRIPTION

The Q3Vector3D_Set function returns, as its function result and in the vector3D parameter, the three-dimensional vector whose scalar components are specified by the x, y, and z parameters.
