Detailed Description

The CSOMath namespace offers some common methods for various problems, e.g., computing the area, mapping from voxel to world or computing numerical problems real fast.

Function Documentation

◆ ceilToInt()

MLCSO_EXPORT int ml::CSOMath::ceilToInt ( const double x )

inline

Returns the ceiled double value as an integer.

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

◆ computeArea()

MLCSO_EXPORT double ml::CSOMath::computeArea	(	const std::vector< Vector3 > &	points,
		const Vector3 &	normal )

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

◆ computeAreaAndCenterOfGravity()

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

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.

Parameters

[in]	points	The points that define the polygon.
[in]	normal	The normal vector of the plane that contains the polygon points.
[in]	centerPoint	The point that is used to create a triangle fan for the calculation of the polygon area. Any point within the polygon plane may be used (e.g. the first path point), but for numerical reasons a point close to the center should be preferred.
[out]	area	Return parameter for the calculated area of the polygon.
[out]	centerOfGravity	Return parameter for the calculated center of gravity of the polygon.
