Function Documentation

getBoundingBox()

void Geometry::getBoundingBox	(	const vector< Vector3d > &	points,
		vector< Vector3d > &	box )

Calculate the bounding box of a group of points.

Parameters

[in]	points	A group of points
[out]	box	The bounding box formed by two points, the left-lower point and the right-upper point

getInsideBox()

bool Geometry::getInsideBox	(	Vector3d	p1,
		Vector3d	p2,
		Vector3d	position )

Verify if a point is inside a box.

Parameters

[in]	p1	Left and lower point of the box
[in]	p2	Right and upper point of the box
[in]	position	Point to be evaluated the function

Returns

True if the point is inside the box, false otherwise

getInsidePolygon()

bool Geometry::getInsidePolygon	(	const vector< Vector3d > &	polygon,
		const Vector3d &	point,
		string	extrude_direction )

Verify in a point is inside of a polygon.

Parameters

[in]	polygon	A list of points forming the polygon
[in]	point	A point to verify if is inside the polygon
[in]	extrude_direction	The normal vector of the plane where the polygon is defined

Returns

True is the point is inside the polygon
