Function Documentation

distancePointPolygon()

double mimmo::mimmoCGUtils::distancePointPolygon	(	const darray3E &	p,
		const dvecarr3E &	vertCoords
	)

Custom method to compute distance from a given polygon of vertices V > 3. The polygon is subdivided in triangles using the polygon barycenter, then distances from each sub-triangle are computed. Return the minimun distance between those calculated.

Parameters

[in]	p	target point coordinates
[in]	vertCoords	vertices of the polygon

Returns

distance from the polygon

isPointInsidePolygon()

bool mimmo::mimmoCGUtils::isPointInsidePolygon	(	const darray3E &	p,
		const dvecarr3E &	vertCoords,
		double	tol
	)

Returns

true if the target point is inside a given polygon of vertices V > 3. The polygon is subdivided in triangles using the polygon barycenter, then check if inside in each sub-triangle is computed.

Parameters

[in]	p	target point coordinates
[in]	vertCoords	vertices of the polygon
[in]	tol	geometric tolerance

Definition at line 109 of file MimmoCGUtils.cpp.

isPointInsideSegment()

bool mimmo::mimmoCGUtils::isPointInsideSegment	(	const darray3E &	p,
		const darray3E &	V0,
		const darray3E &	V1,
		double	tol
	)

Returns

true if the target point is inside the segment V0-V1

Parameters

[in]	p	target point coordinates
[in]	V0	segment first vertex
[in]	V1	segment second vertex
[in]	tol	geometric tolerance

Definition at line 67 of file MimmoCGUtils.cpp.

isPointInsideTriangle()

bool mimmo::mimmoCGUtils::isPointInsideTriangle	(	const darray3E &	p,
		const darray3E &	V0,
		const darray3E &	V1,
		const darray3E &	V2,
		double	tol
	)

Returns

true if the target point is inside the triangle V0-V1-V2

Parameters

[in]	p	target point coordinates
[in]	V0	triangle first vertex
[in]	V1	triangle second vertex
[in]	V2	triangle third vertex
[in]	tol	geometric tolerance
