Detailed Description

Abstract Base Class for RayIntersectors. A RayIntersector performs an intersection-test between a ray and a shape. All intersections are reported by passing an `IntersectionInfo' to a callback.

virtual ID VRS::RayIntersector::service

(

)

const [virtual]

The service name of ray intersectors is RayIntersector.

Reimplemented from VRS::Handler.

virtual bool VRS::RayIntersector::intersect	(	Engine *	ctx,
		const Matrix &	mv,
		const Matrix &	ori,
		const Matrix &	pr,
		const Shape *	S,
		const Ray &	r,
		RayTracingTechnique *	tracer
	)			[pure virtual]

`S' is the shape that is actually tested. If the intersector finds an intersection point, it has to callback tracer->registerIntersection().

Implemented in EnvironmentRenderer::GreenSpaceCompositeRayIntersector, EnvironmentRenderer::GreenSpaceRayIntersector, EnvironmentRenderer::PolygonSetWaterSurfaceRayIntersector, EnvironmentRenderer::WaterSurfaceRayIntersector, VRS::BatchTreeRayIntersectorGL, VRS::MappedVertexAttributeShapeRayIntersectorGL, VRS::PrimitiveQuadTreeAreaRayIntersectorGL, VRS::PrimitiveQuadTreeDistanceRayIntersectorGL, VRS::TexturedBatchTreeRayIntersectorGL, VRS::PolygonSetRayIntersector, VRS::TEXT::DisplacedTextureTextRayIntersector, VRS::TEXT::FontLodTextRayIntersector, VRS::TEXT::SimplePanelRayIntersector, and VRS::TEXT::TextureTextRayIntersector.
