This call moves the camera in the forward direction by the specified distance.

void RayCamera::moveRight (  float  dist  )

This call moves the camera in the right direction by the specified distance.

void RayCamera::moveUp (  float  dist  )

This call moves the camera in the up direction by the specified distance.

int RayCamera::read (  FILE *  fp  )

This method reads in the camera information from a .ray file.

void RayCamera::rotateRight (  Point3D  center, float  angle )

This call rotates the camera, about the axis which is parallel to the right direction of the camera, and passes through the specified point.

void RayCamera::rotateUp (  Point3D  center, float  angle )

This call rotates the camera, about the axis which is parallel to the up direction of the camera, and passes through the specified point.

void RayCamera::write (  FILE *  fp = stdout  )

This method writes out the camera information to a .ray file. If no file is specified, the camera is written out to stdout.
