Detailed Description

A base class of the scene.

Member Function Documentation

Scene::LM_INTERFACE_F	(	0	,
		Initialize	,
		bool(const PropertyNode *, Assets *, Accel *)
	)

Initialize the scene.

Initializes the scene from the given property of the scene configuration file.

Scene::LM_INTERFACE_F	(	1	,
		Intersect	,
		bool(const Ray &ray, Intersection &)
	)

Intersection query.

The function checks if ray hits with the scene. Returns true if the ray intersected, otherwise returns false. The 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.

Scene::LM_INTERFACE_F	(	3	,
		PrimitiveByID	,
		const Primitive *	const std::string &
	)

Get a primitive by ID.

Parameters

id	ID of a primitive.

Returns

Primitive.

Scene::LM_INTERFACE_F	(	5	,
		PrimitiveAt	,
		const Primitive *	int index
	)

Get a primitive by index.

Parameters

index

Index of a primitive.
