Detailed Description

A Ray Query class used for computing ray object intersections.

gz/rendering/ogre2/Ogre2RayQuery.hh

Constructor & Destructor Documentation

◆ Ogre2RayQuery()

Ogre2RayQuery ( )

protected

Constructor.

◆ ~Ogre2RayQuery()

virtual ~Ogre2RayQuery ( )

virtual

Destructor.

Member Function Documentation

◆ ClosestPoint()

virtual RayQueryResult ClosestPoint ( bool _forceSceneUpdate = true )

virtual

Compute intersections.

Parameters

[in] _forceSceneUpdate Performance optimization hint When true Ogre2 will update all derived transforms to their latest to get correct results.

When false, that step is skipped. It is only safe to set it to false when nothing has changed since the last update (i.e. nothing moved, no new objects created).

Ogre will assert if built in Debug mode if this value is set to false when it shouldn't be.

See https://ogrecave.github.io/ogre-next/api/2.2/ _ogre20_changes.html::AssersionCachedOutOfDate for more info

Returns: A vector of intersection results

Reimplemented from BaseRayQuery< Ogre2Object >.

◆ SetFromCamera()

virtual void SetFromCamera	(	const CameraPtr &	_camera,
		const math::Vector2d &	_coord
	)

virtual

Create the ray query from camera.

Parameters

[in]	_camera	Camera to construct ray
[in]	_coord	normalized device coords [-1, +1]

Reimplemented from BaseRayQuery< Ogre2Object >.
