Q3Matrix4x4_SetRotate_XYZ

You can use the Q3Matrix4x4_SetRotate_XYZ function to configure a 4-by-4 transformation matrix that rotates objects around all three coordinate axes.

TQ3Matrix4x4 *Q3Matrix4x4_SetRotate_XYZ (
TQ3Matrix4x4 *matrix4x4, 
float xAngle, 
float yAngle, 
float zAngle);

matrix4x4

A 4-by-4 matrix.

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 Q3Matrix4x4_SetRotate_XYZ function returns, as its function result and in the matrix4x4 parameter, a rotational matrix that rotates an object by the specified angles around the x, y, and z axes.
