v4fChange

Description

Change the given homogeneous vectors with a multiple of the source.

Syntax

*v4fTarget.UBE_VECTOR4f = UBE_v4fChange( *v4fTarget.UBE_VECTOR4f,
                                         *v4fSource.UBE_VECTOR4f, Factor.f )

Parameters

*v4fTarget	A valid pointer to a homogeneous vector (Result and left operand).
*v4fSource	A valid pointer to a homogeneous vector (Right operand).
Factor	The multiplication factor of the source vector.

Return value

The pointer to the result homogeneous vector.

Remarks

T_x = T_x + f·S_x
T_y = T_y + f·S_y
T_z = T_z + f·S_z
T_w = max( T_w, S_w )
