示例1: checkIntersection
point line::checkIntersection( const line & line2 ) const
{
// now the real work begins
// lets try this using determinants
// converting to form Ax + By = C
float A1 = _y2 - _y1;
float B1 = _x1 - _x2;
float C1 = ( A1 * _x1 ) + ( B1 * _y1 );
float A2 = line2.getPoint2().y - line2.getPoint1().y;
float B2 = line2.getPoint1().x - line2.getPoint2().x;
float C2 = ( A2 * line2.getPoint1().x ) + ( B2 * line2.getPoint1().y );
float det = ( A1 * B2 ) - ( A2 * B1 );
// parallel test
if ( det == 0 ) point( 0, 0 );
float x_intersect = ( ( B2 * C1 ) - ( B1 * C2 ) ) / det;
float y_intersect = ( ( A1 * C2 ) - ( A2 * C1 ) ) / det;
return point( x_intersect, y_intersect );
