Function Documentation

bool CheckLibraryPath (   )

Help avoid problems with library paths. Especially on Darwin/OSX. Returns: true if have the proper path. False if found something bad or lacking

bool CheckTypeValid (  const string &  type  )

Check with coin/simage to see if the image extension works. Parameters: type  String of the file extension. For example rgb, png, jpg Returns: false if something went really bad with the lookup.

vector<float> InterpolatePos (  const vector< float > &  v1, const vector< float > &  v2, const float  percent )

SbRotation InterpolateRotations (  const SbRotation &  rot1, const SbRotation &  rot2, const float  percent )

SbVec3f InterpolateVec (  const SbVec3f &  v1, SbVec3f &  v2, const float  percent )

void ListWriteFileTypes (   )

Handle the --list command line option. Spits out the list of filetypes that work for rendering to files.

bool LoadSpotLightDraggers (  const string  filename, SoSeparator *  root, vector< SoSpotLightDragger * > &  draggerVec )

Load dragger/way points from a disk file. Parameters: filename  Ascii file to load from root  Where in the scene graph location to add the draggers (should be draggerSwitch draggerVec  A vector in which to keep the way points handy Returns: false if trouble loading the draggers/waypoints

bool RenderFrameToDisk (  const string &  basename, const string &  filetype, const int  width, const int  height, SoNode *  root, size_t &  frame_num, const SbColor &  background )

Ship off a picture to disk. Parameters: basename  start the file name with this filetype  the extension for the image format: jpg, png, etc... width,height  The size of the rendered frame root  Top of the scene graph to render frame_num  return the frame number that we wrote Returns: false if we flailed trying to get a pretty picture to disk Bug: FIX: could optimize by keeping one renderer in memory

bool SaveSpotLightDraggersAscii (  const string &  filename, vector< SoSpotLightDragger * > &  draggerVec )

Save an ascii file of all the draggers for editing and reloading. Parameters: filename  file to write to draggerVec  pointers to all the SoSpotLightDragger way points Returns: false if had trouble writing the file

void SetCameraFromDragger (  SoCamera *  c, SoSpotLightDragger *  d )

Given a draggers set the camera view from it. This is the simpler case where we do not have to interpolate between to draggers

SbVec3f ToSbVec3f (  const vector< float > &  v  )

vector<float> ToVector (  const SbVec3f &  SbV  )

bool WriteSceneGraph (  const string &  filename, SoNode *  root )

Write a scene graph to disk as ascii. Parameters: filename  File to write ascii IV file to root  Starting point of the scene graph to same Returns: false if we were not able to open the file.
