Detailed Description

This class stores all of the information describing the geometry in a scene

Member Function Documentation

_read()

void SceneGeometry::_read ( std::istream &  stream )

privatevirtual

This method reads the Shape from the stream (excluding the starting directive)

Implements Ray::Shape.

_write()

void SceneGeometry::_write ( std::ostream &  stream ) const

privatevirtual

This method writes the Shape into the stream (including the starting directive)

Implements Ray::Shape.

drawOpenGL()

void SceneGeometry::drawOpenGL ( GLSLProgram *  glslProgram ) const

virtual

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

Implements Ray::Shape.

init() [1/2]

void SceneGeometry::init

(

const LocalSceneData &

sceneData

)

init() [2/2]

void SceneGeometry::init

(

void

)

Initializes the scene geometry, transforming property indices to pointers

initOpenGL()

void SceneGeometry::initOpenGL ( void  )

virtual

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

Implements Ray::Shape.

Reimplemented in Ray::Scene.

isInside()

bool SceneGeometry::isInside ( Util::Point3D  p ) const

virtual

This method determines if a point is inside a shape. It is assumed that if the shape is not water-tight, the method returns false.

Implements Ray::Shape.

name()

std::string Ray::SceneGeometry::name ( void  ) const

inlinevirtual

This method returns the name of the shape

Implements Ray::Shape.

processAllIntersections()

int SceneGeometry::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.

Implements Ray::Shape.

Reimplemented in Ray::Scene.

processFirstIntersection()

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

virtual

This method processes the first shape which intersect the ray within the prescribed range and passing the rFilter test, invoking the rKernel kernel with the intersection information. The function returns true if there was an intersection.

Implements Ray::Shape.

Reimplemented in Ray::Scene.

processOverlapping()

void SceneGeometry::processOverlapping ( const Filter &  filter, const Kernel &  kernel, ShapeProcessingInfo  spInfo  ) const

virtual

This method process Shapes by calling the "kernel" function on every shape whose bounding box passes the "filter" test. The tInfo parameter stores the accumulation of transformations encountered when traversing the scene-graph. Note that the bounding box is in the coordinate frame of the node.

Reimplemented from Ray::Shape.

setCurrentTime()

void SceneGeometry::setCurrentTime	(	double	t,
		int	curveFit
	)

This method updates the current time, changing the parameter values as needed

setKeyFrameEvaluator()

template<typename ParameterType >

void Ray::SceneGeometry::setKeyFrameEvaluator

(

void

)

This templated method sets the key frame evaluator using the prescribed type of parameter

updateBoundingBox()

void SceneGeometry::updateBoundingBox ( void  )

virtual

This method should be called to update the bounding boxes in the scene

Implements Ray::Shape.

Member Data Documentation

_localData

LocalSceneData Ray::SceneGeometry::_localData

private
