Q3RationalPoint3D_Set

You can use the Q3RationalPoint3D_Set function to set the coordinates of a three-dimensional rational point.

TQ3RationalPoint3D *Q3RationalPoint3D_Set (
TQ3RationalPoint3D *point3D, 
float x, 
float y, 
float w);

point3D

A three-dimensional point.

x

The x coordinate of the point.

y

The y coordinate of the point.

w

The w coordinate of the point.

DESCRIPTION

The Q3RationalPoint3D_Set function returns, as its function result and in the point3D parameter, the three-dimensional rational point specified by the x, y, and w parameters.
