Member Function Documentation

◆ CircleAndCircle()

void QCollision::CircleAndCircle	(	vector< QParticle * > &	particlesA,
		vector< QParticle * > &	particlesB,
		QAABB	boundingBoxB,
		vector< QCollision::Contact * > &	contacts,

	)

static

Checks collisions between circle(s) and circle(s).

Parameters

particlesA	A collection of particles representing one or more circles, each having a radius.
particlesB	Another collection of particles representing one or more circles, each having a radius.
contacts	A collection where collision contact information will be stored.

◆ CircleAndPolygon()

void QCollision::CircleAndPolygon	(	vector< QParticle * > &	circleParticles,
		vector< QParticle * > &	polygonParticles,
		vector< QCollision::Contact * > &	contacts
	)

static

Checks collisions between circle(s) and polygon.

Parameters

particlesA	A collection of particles representing one or more circles, each having a radius.
particlesB	A collection of particles that make up a polygon.
contacts	A collection where collision contact information will be stored.

◆ CircleAndPolyline()

void QCollision::CircleAndPolyline	(	vector< QParticle * > &	circleParticles,
		vector< QParticle * > &	polylineParticles,
		QAABB	polylineAABB,
		vector< QCollision::Contact * > &	contacts,
		bool	circlesArePolygon = `false`
	)

static

Checks collisions between circles and polyline.

Parameters

circleParticles	A collection of particles representing one or more circles, each having a radius.
polylineParticles	A collection of particles that make up a polyline.
polylineAABB	AABB of polyline for tests between circle and AABB.
contacts	A collection where collision contact information will be stored.
circlesArePolygon	It defines whether circle particles is the part of a polygon.

◆ LineIntersectionLine()

QVector QCollision::LineIntersectionLine	(	QVector	d1A,
		QVector	d1B,
		QVector	d2A,
		QVector	d2B
	)

static

Checks intersection between lines.

Parameters

d1A	The point A of the d1 line.
d1B	The point B of the d1 line.
d2A	The point A of the d2 line.
d2B	The point B of the d2 line.

Returns: An intersection position. If the intersection doesn't exist, returns QVector::NaN.

◆ PointInPolygon() [1/2]

bool QCollision::PointInPolygon	(	QVector &	point,
		vector< QParticle * > &	polygon
	)

static

Checks whether a specified point is inside the specified polygon.

Parameters

point	A point to check.
polygon	A collection of particles that make up a polygon.

Returns: Returns true if the point is inside the polygon, false otherwise.

◆ PointInPolygon() [2/2]

bool QCollision::PointInPolygon	(	QVector &	point,
		vector< QVector > &	polygon
	)

static

Checks whether a specified point is inside the specified polygon.

Parameters

point	A point to check.
polygon	A collection of vectors that make up a polygon.

Returns: Returns true if the point is inside the polygon, false otherwise.

◆ PointInPolygon2()

bool QCollision::PointInPolygon2	(	QVector	point,
		vector< QParticle * > &	polygon
	)

static

Checks whether a specified point is inside the specified particle polygon.

Parameters

point	A point to check.
polygon	A collection of particles that make up a polygon.

Returns: Returns true if the point is inside the polygon, false otherwise.

◆ PolygonAndPolygon()

void QCollision::PolygonAndPolygon	(	vector< QParticle * > &	particlesA,
		vector< QParticle * > &	particlesB,
		vector< QCollision::Contact * > &	contacts
	)

static

Checks collisions between polygons.

Parameters

particlesA	A collection of particles that make up a polygon.
particlesB	Another collection of particles that make up a polygon.
contacts	A collection where collision contact information will be stored.

◆ PolylineAndPolygon()

void QCollision::PolylineAndPolygon	(	vector< QParticle * > &	polylineParticles,
		vector< QParticle * > &	polygonParticles,
		vector< QCollision::Contact * > &	contacts
	)

static

Checks collisions between polyline and polygon.

Parameters

polylineParticles	A collection of particles that make up a polyline.
polygonParticles	Another collection of particles that make up a polygon.
contacts	A collection where collision contact information will be stored.

Note: To check collisions between two polylines, call this method twice with the polylines swapped as arguments.; "Polyline" is commonly used to define polygons for softbody objects. In contrast to a solid and filled polygon , you can think of a polyline as a polygon shape formed by a connected and knotted rope. If a polygon-shaped rope is deformed, it may not always remain a polygon, it can overlap and its corners can merge. Collision testing for a polyline is performed based on these assumptions
