Member Function Documentation

bool BVHScene::Build ( )

overridevirtual

Build acceleration structure. Some scene may have an acceleration structure for the optimization. The function must be called after Load. The function must be called before any intersection queries.

Return values

true	Succeeded to build.
false	Failed to build.

Implements Scene.

virtual bool BVHScene::Configure ( const ConfigNode & node )

inlineoverridevirtual

Configure the scene.

Parameters

node	XML node for the configuration.

Return values

true	Succeeded to configure the scene.
false	Failed to configure the scene.

Implements Scene.

virtual boost::signals2::connection BVHScene::Connect_ReportBuildProgress ( const std::function< void(double, bool)> & func )

inlineoverridevirtual

Connect to ReportBuildProgress signal. The signal is emitted when the progress of asset loading is changed.

Parameters

func	Slot function.

Implements Scene.

virtual AABB BVHScene::GetAABBTriangles ( ) const

inlineoverridevirtual

Get AABB of triangles in the scene.

Returns: AABB of triangles in the scene.

Implements Scene.

bool BVHScene::IntersectTriangles	(	Ray &	ray,
		Intersection &	isect
	)		const

overridevirtual

Intersection query with triangles. The function checks if #ray hits with the scene. This function is supposed to be accelerated by spatial acceleration structure. When intersected, information on the hit point is stored in the intersection data.

Parameters

ray	Ray.
isect	Intersection data.

Return values

true	Intersected with the scene.
false	Not intersected with the scene.

Implements Scene.
