Detailed Description

This class stores all of the information read out from a .ray file.

Member Function Documentation

drawOpenGL()

void Scene::drawOpenGL

(

void

)

const

This method calls the necessary OpenGL commands to render the primitive.

getColor()

Point3D Scene::getColor	(	Util::Ray3D	ray,
		int	rDepth,
		Util::Point3D	cLimit,
		unsigned int	lightSamples,
		unsigned int	tIdx
	)

This is the function responsible for the recursive ray-tracing returning the color obtained by shooting a ray into the scene and recursing until either the recursion depth has been reached or the contribution from subsequent bounces is guaranteed to be less than the cut-off.

initOpenGL()

void Scene::initOpenGL ( void  )

virtual

This method should be called (once) after an OpenGL context has been created

Reimplemented from Ray::SceneGeometry.

processAllIntersections()

int Scene::processAllIntersections ( const Util::Ray3D &  ray, const Util::BoundingBox1D &  range, const RayIntersectionFilter &  rFilter, const RayIntersectionKernel &  rKernel, ShapeProcessingInfo  spInfo, unsigned int  tIdx  ) const

virtual

This method processes all shapes which intersect the ray within the prescribed range and passing the rFilter test, invoking the rKernel kernel with the intersection information. The processing terminates early if the kernel returns false. The function returns the number of valid intersections.

Reimplemented from Ray::SceneGeometry.

processFirstIntersection()

bool Scene::processFirstIntersection ( const Util::Ray3D &  ray, const Util::BoundingBox1D &  range, const RayIntersectionFilter &  rFilter, const RayIntersectionKernel &  rKernel, ShapeProcessingInfo  spInfo, unsigned int  tIdx  ) const

virtual

This method ray-traces the primitive

Reimplemented from Ray::SceneGeometry.

rayTrace()

Image32 Scene::rayTrace	(	int	width,
		int	height,
		int	rLimit,
		double	cLimit,
		unsigned int	lightSamples,
		bool	showProgress
	)

This method ray-traces the scene and returns the computed image

Reflect()

Point3D Scene::Reflect ( Util::Point3D  v, Util::Point3D  n  )

static

This function reflects the vector v about the normal n.

Refract()

bool Scene::Refract ( Util::Point3D  v, Util::Point3D  n, double  ir, Util::Point3D &  refract  )

static

This function will refract the vector about the normal using the provided indices of refraction. The refracted vector is written into refract and a value of true is returned if the refraction succeeded (i.e. the necessary arcsin could be computed).
