Scene Class Reference

The Scene class provides access to geometry and collision detection methods. Furthermore, some game logic is implemented, so the scene holds the player, the gem influenced by player and cameras. More...

AbstractGem * Scene::findGemIntersectedBy	(	const LightRay &	ray,
		QVector3D *	collisionPoint = nullptr
	)		const

Finds the nearest gem with bounding sphere intersected by given ray.

Parameters

ray	Ray sent into scene to find gem.
collisionPoint	Optional parameter. The point of collision is written into.

Returns

Returns the nearst intersected gem. Never returns nullptr;

AbstractGem * Scene::findGemWithBoundingSphereIntersectedBy	(	const LightRay &	ray,
		QVector3D *	collisionPoint = nullptr
	)		const

Finds the nearest gem, that bounding sphere is intersected by given ray.

Parameters

ray	Ray sent into scene to find gem.
collisionPoint	Optional parameter. The point of collision is written into. Only if no nullptr is returned this value is usable.

Returns

Returns the nearst intersected gem. nullptr.

Returns

Returns a List of Gems which is supported by QML.
