20 Determining Point Affine Combinations
Q3RationalPoint4D_AffineComb
function to determine the rational four-dimensional point that is the affine combination of an array of points.
TQ3RationalPoint4D *Q3RationalPoint4D_AffineComb ( const TQ3RationalPoint4D *points4D, const float *weights, unsigned long nPoints, TQ3RationalPoint4D *result);points4D
A pointer to an array of rational four-dimensional points.weights
A pointer to an array of weights. The weights must sum to 1.0.nPoints
The number of points in thepoints4D
array.result
On exit, the point that is the affine combination of the points inpoints4D
which have the weights in theweights
array.
Q3RationalPoint4D_AffineComb
function returns, as its function result and in the result
parameter, the rational point that is the affine combination of the points in the array points4D
which have the weights in the array weights
.
