Member Function Documentation

int RayKeyFile::index (  char *  name  )

This method returns the index of the parameter with the specified name. -1 is returned if no parameter matches the name.

const char * RayKeyFile::name (  int  i  )

This method returns the name of the i-th parameter

Matrix4D * RayKeyFile::operator[] (  int  i  )

This method provides access to the i-th row of transformation information. The ordering is such that the (i,j)-th entry corresponds to the i-th sample of the j-th parameter.

int RayKeyFile::parameters (  void   )

This method returns the number of parameters stored.

int RayKeyFile::read (  char *  fileName  )

This method reads in the transformation data from the specified file

int RayKeyFile::samples (  void   )

This method returns the number of key-frames stored.

int RayKeyFile::write (  char *  fileName  )

This method writes out the transformation data to the specified file
