Q3Quaternion_Set

You can use the Q3Quaternion_Set function to set the components of a quaternion.

TQ3Quaternion *Q3Quaternion_Set (
TQ3Quaternion *quaternion, 
float w, 
float x, 
float y, 
float z);

quaternion

A quaternion.

w

The desired w component of a quaternion.

x

The desired x component of a quaternion.

y

The desired y component of a quaternion.

z

The desired z component of a quaternion.

DESCRIPTION

The Q3Quaternion_Set function returns, as its function result and in the quaternion parameter, the quaternion whose components are specified by the w, x, y, and z parameters.
