Q3RationalPoint4D_Set

You can use the Q3RationalPoint4D_Set function to set the coordinates of a four-dimensional rational point.

TQ3RationalPoint4D *Q3RationalPoint4D_Set (
TQ3RationalPoint4D *point4D, 
float x, 
float y, 
float z, 
float w);

point4D

A four-dimensional point.

x

The x coordinate of the point.

y

The y coordinate of the point.

z

The z coordinate of the point.

w

The w coordinate of the point.

DESCRIPTION

The Q3RationalPoint4D_Set function returns, as its function result and in the point4D parameter, the four-dimensional rational point specified by the x, y, z, and w parameters.
