Q3Quaternion_SetRotateXYZ

You can use the Q3Quaternion_SetRotateXYZ function to configure a quaternion having a specified rotation around the x, y, and z axes.

TQ3Quaternion *Q3Quaternion_SetRotateXYZ (
TQ3Quaternion *quaternion, 
float xAngle, 
float yAngle, 
float zAngle);

quaternion

A quaternion.

xAngle

The desired angle of rotation around the x axis, in radians.

yAngle

The desired angle of rotation around the y axis, in radians.

zAngle

The desired angle of rotation around the z axis, in radians.

DESCRIPTION

The Q3Quaternion_SetRotateXYZ function returns, as its function result and in the quaternion parameter, a quaternion that rotates an object by the specified angles around the x, y, and z axes.
