Detailed Description

This class represents a node which stores a triangle list. It's children can only be Triangles or TrivialShapeLists.

Constructor & Destructor Documentation

TriangleList()

TriangleList::TriangleList

(

void

)

The default constructor

Member Function Documentation

_read()

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

privatevirtual

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

Reimplemented from Ray::ShapeList.

_write()

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

privatevirtual

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

Reimplemented from Ray::ShapeList.

Directive()

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

inlinestatic

This static method returns the directive header describing the shape.

drawOpenGL()

void TriangleList::drawOpenGL ( GLSLProgram *  glslProgram ) const

virtual

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

Reimplemented from Ray::ShapeList.

init()

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

virtual

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

Reimplemented from Ray::ShapeList.

initOpenGL()

void TriangleList::initOpenGL ( void  )

virtual

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

Reimplemented from Ray::ShapeList.

name()

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

inlinevirtual

This method returns the name of the shape

Reimplemented from Ray::ShapeList.

processAllIntersections()

int TriangleList::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::ShapeList.

processFirstIntersection()

bool TriangleList::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.

Reimplemented from Ray::ShapeList.

processOverlapping()

void TriangleList::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::ShapeList.
