transformPoints method

void transformPoints(
  1. List<double> points
)

Implementation

void transformPoints(List<double> points) {
  final maxI = points.length - 1; // points.length must be even
  for (int i = 0; i < maxI; i += 2) {
    final x = points[i];
    final y = points[i + 1];
    final denominator = a13 * x + a23 * y + a33;
    points[i] = (a11 * x + a21 * y + a31) / denominator;
    points[i + 1] = (a12 * x + a22 * y + a32) / denominator;
  }
}
