In Scene graph view, it will coredump when you rubberband beyond the upper or left margin of the graph and select Expand. This is a SgGraph bug and is or will be fixed.

Type "pfview". Select File->Open to insert any Performer loadable file -- we've included flint.sv and pitts.dwb.

Other files are included in /usr/share/Pfview. If you installed performer_eoe.sw.data the flint.sv model will have textures.

AMENDMENTS MADE 2/20/96 by Eric Burke (eburke@engr.sgi.com):

1. Removed all non-functional menu items. The new menus are as follows:

       File->Open...	Open a modelfile for viewing
       File->Exit		Exit the program
   
       View->Reset		Return to original orientation of the model
       View->Selector...	Show graphical representation of scene graph
       View->Axis		Toggle the axis on/off
       View->Wireframe	Toggle wireframe/filled drawing
       View->Texture	Toggle texture mapping on/off
   

2. Viewer is now an encapsulated class.

3. There is no button to scale the model (on the right margin decorations).

4. The rubberband bug in the graph has been fixed.

   Software requirements:

   RapidApp 1.2 (ONLY)
   ViewKit_dev
   WorkShop (optional)
   Performer 2.0

• if you have WorkShop.sw.cvstatic loaded, you can uncomment the

      #SADIR= iltest.cvdb
      #SAFLAG= -sa,$(SADIR)
      #$(OBJECTS):$(SADIR)/cvdb.dbd
      #$(SADIR)/cvdb.dbd :
      #       [ -d $(SADIR) ] || mkdir $(SADIR)
      #       cd $(SADIR); initcvdb.sh
      #
      #LDIRT=$(SADIR) vista.taf
  

  lines near the bottom of the Makefile.

• make sure you do a "setenv XUSERFILESEARCHPATH ./%N%S" before running the program so the app-defaults file is picked up from the current directory. (see pfview.sh for one way to invoke/run this from the shell.)
