void RayScene::drawOpenGL (  void   )

This method calls the OpenGL commands for drawing the scene.

Point3D RayScene::GetColor (  Ray3D  ray, int  rDepth, Point3D  cLimit )

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.

RayMaterial * RayScene::getMaterial (  int  index  )

This method returns the material with the specified index.

Ray3D RayScene::GetRay (  RayCamera *  camera, int  i, int  j, int  width, int  height )  [static]

This function returns that leaves the camera and goes through pixel (i,j) of the view plane

int RayScene::read (  FILE *  fp, int  transformType )

This method reads in the scene-graph from a .ray file.

int RayScene::read (  char *  fileName, int  transformType = RayKeyData::MATRIX )

This method reads in the scene-graph from a .ray file.

Point3D RayScene::Reflect (  Point3D  v, Point3D  n )  [static]

This function will reflect the vector v about the normal n

int RayScene::Refract (  Point3D  v, Point3D  n, double  ir, 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 1 is returned if the refraction succeeded (i.e. the necessary arcsin could be computed)

void RayScene::setCurrentTime (  double  t, int  curveFit = LINEAR )

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

void RayScene::setUpOpenGL (  int  cplx  )

This method class the OpenGL commands to set up everything that needs to be set up prior to rendering

int RayScene::write (  FILE *  fp = stdout  )

This method writes out the scene-graph to a .ray file. If no file is specified the scene-graph is written out stdout.

int RayScene::write (  char *  fileName  )

This method writes out the scene-graph to a .ray file.
