Detailed Description

This class represents a cone whose central axis is parallel to the y-axis, and is defined by the center of the cone, the height from the tip to the base and the base of the cone.

Constructor & Destructor Documentation

Cone()

Cone::Cone

(

void

)

The default constructor

Member Function Documentation

_read()

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

privatevirtual

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

Implements Ray::Shape.

_write()

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

privatevirtual

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

Implements Ray::Shape.

Directive()

static std::string Ray::Cone::Directive ( void  )

inlinestatic

This static method returns the directive describing the shape.

drawOpenGL()

void Cone::drawOpenGL ( GLSLProgram *  glslProgram ) const

virtual

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

Implements Ray::Shape.

init()

void Cone::init ( const class LocalSceneData &  data )

virtual

This method should be called (once) immediately after setting up the scene graph

Implements Ray::Shape.

initOpenGL()

void Cone::initOpenGL ( void  )

virtual

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

Implements Ray::Shape.

isInside()

bool Cone::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::Cone::name ( void  ) const

inlinevirtual

This method returns the name of the shape

Implements Ray::Shape.

processAllIntersections()

int Cone::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.

processFirstIntersection()

bool Cone::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.

updateBoundingBox()

void Cone::updateBoundingBox ( void  )

virtual

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

Implements Ray::Shape.
