int Geometry::abcFormula (  double    a, double    b, double    c, double *    s1, double *    s2 )  [static]

This method performs the abc formula (Pythagoras' Theorem) on the given parameters and puts the result in *s1 en *s2. It returns the number of found coordinates. Parameters: a  a parameter in abc formula b  b parameter in abc formula c  c parameter in abc formula s1  first result of abc formula s2  second result of abc formula Returns: number of found x-coordinates Definition at line 1121 of file Geometry.cpp. References EPSILON. Referenced by Line::getCircleIntersectionPoints().

double Geometry::getFirstGeomSeries (  double    dSum, double    dRatio, double    dLength )  [static]

A geometric series is one in which there is a constant ratio between each element and the one preceding it. This method determines the first element of a geometric series given its element, the ratio and the number of steps in the series Normally: s = a + ar + ar^2 + ... + ar^n Now: dSum = dFirst + dFirst*dRatio + ... + dFirst*dRatio^dSteps Parameters: dSum  sum of the series dRatio  ratio with which the the first term is multiplied dSum  the number of steps to be taken into account Returns: the first element (a) of a serie Definition at line 1086 of file Geometry.cpp. Referenced by WorldModel::getFirstSpeedFromDist().

double Geometry::getFirstInfGeomSeries (  double    dSum, double    dRatio )  [static]

A geometric series is one in which there is a constant ratio between each element and the one preceding it. This method determines the first element of an infinite geometric series given its first element and the constant ratio between the elements. Note that such an infinite series will only converge when 0<r<1. Normally: s = a + ar + ar^2 + ar^3 + .... Now: dSum = dFirst + dFirst*dRatio + dFirst*dRatio^2... Parameters: dSum  sum of the series dRatio  ratio with which the the first term is multiplied Returns: the first term of the series Definition at line 1103 of file Geometry.cpp. Referenced by WorldModel::getKickSpeedToTravel().

double Geometry::getLengthGeomSeries (  double    dFirst, double    dRatio, double    dSum )  [static]

A geometric series is one in which there is a constant ratio between each element and the one preceding it. This method determines the length of a geometric series given its first element, the sum of the elements in the series and the constant ratio between the elements. Normally: s = a + ar + ar^2 + ... + ar^n Now: dSum = dFirst + dFirst*dRatio + dFirst*dRatio^2 + .. + dFist*dRatio^n Parameters: dFirst  first term of the series dRatio  ratio with which the the first term is multiplied dSum  the total sum of all the serie Returns: the length(n in above example) of the series Definition at line 1026 of file Geometry.cpp. Referenced by WorldModel::getKickSpeedToTravel().

double Geometry::getSumGeomSeries (  double    dFirst, double    dRatio, double    dLength )  [static]

A geometric series is one in which there is a constant ratio between each element and the one preceding it. This method determines the sum of a geometric series given its first element, the ratio and the number of steps in the series Normally: s = a + ar + ar^2 + ... + ar^n Now: dSum = dFirst + dFirst*dRatio + ... + dFirst*dRatio^dSteps Parameters: dFirst  first term of the series dRatio  ratio with which the the first term is multiplied dSum  the number of steps to be taken into account Returns: the sum of the series Definition at line 1050 of file Geometry.cpp. Referenced by WorldModel::predictPosAfterNrCycles().

double Geometry::getSumInfGeomSeries (  double    dFirst, double    dRatio )  [static]

A geometric series is one in which there is a constant ratio between each element and the one preceding it. This method determines the sum of an infinite geometric series given its first element and the constant ratio between the elements. Note that such an infinite series will only converge when 0<r<1. Normally: s = a + ar + ar^2 + ar^3 + .... Now: dSum = dFirst + dFirst*dRatio + dFirst*dRatio^2... Parameters: dFirst  first term of the series dRatio  ratio with which the the first term is multiplied Returns: the sum of the series Definition at line 1067 of file Geometry.cpp. Referenced by BasicPlayer::getActiveInterceptionPointBall(), BasicPlayer::getInterceptionPointBall(), and WorldModel::predictFinalAgentPos().
