Member Function Documentation

static void ml::CSOMath::appendUniquePosition	(	std::vector< Vector3 > &	positions,
		Vector3	pos
	)			`[inline, static]`

Deprecated:: Call the method from CSOGeometry directly.

Definition at line 147 of file CSOMath.h.

static bool ml::CSOMath::areInSamePlane	(	CSO *	cso0,
		CSO *	cso1
	)			`[inline, static]`

Deprecated:: Call the method from CSOGeometry directly.

Definition at line 129 of file CSOMath.h.

static int ml::CSOMath::ceilToInt ( const double x ) [inline, static]

Returns the ceiled double value as an integer.

On WIN32 platforms this function uses a faster implementation using inline assembler.

Definition at line 71 of file CSOMath.h.

static double ml::CSOMath::computeArea	(	const std::vector< Vector3 > &	points,
		const Vector3 &	normal
	)			`[static]`

Computes the area of the polygon, given as a list of points.

static void ml::CSOMath::computeAreaAndCenterOfGravity	(	const std::vector< Vector3 > &	points,
		const Vector3 &	normal,
		const Vector3 &	centerPoint,
		double &	area,
		Vector3 &	centerOfGravity
	)			`[static]`

Computes the area and center of gravity (in terms of area) of the polygon, given as a list of points.

In contrast to CSOGeometry::getCenterOfGravity(), this method defines the center of gravity as the center of the enclosed area.

static double ml::CSOMath::computeDirectionDotProduct	(	const Vector3 &	predPos,
		const Vector3 &	middlePos,
		const Vector3 &	succPos
	)			`[static]`

Computes and returns the dot product of the direction vectors of pred-middle and middle-succ.

Definition at line 155 of file CSOMath.h.

static float ml::CSOMath::fast_log ( float value ) [inline, static]

Calculates the natural logarithm based on an approximation using a look up table.

No bounds checking is performed and thus only values >0 are allowed as parameter.

Definition at line 85 of file CSOMath.h.

static int ml::CSOMath::floorToInt ( const double x ) [inline, static]

Returns the floored double value as an integer.
