UNFORTUNATELY,

we were unsuccessful in recompiling DirectManipRevoSurf on IRIX 6.2.

As the author, who was time-strapped, wrote the janitor,

RevoSurfEngine dso doesn't load so the program is essentially useless. I think it has to do with how the .so file is being made. I'm using ld instead of CC or something but I don't know the solution.

However, pursuing our goal of extending collaboration between the DTjanitor and everyone in the Developer Program, although we were not able to port/successfully recompile this source to/on IRIX 6.2, we still include all src files so that, if any one of you has the saavy, and finds the inclination/motivation enabling you to succeed in reviving oat, PLEEZE send us whatever files (source, Makefile, etc.) you modify to "make it go" again, and we will add these back into the v6.2 DT release as resuscitated src+binaries.

    draggers implementation for direct manipulation of surface of revolution


          Recently someone posted a question (on comp.sys.sgi.graphics) 
          about using Inventor manipulators to edit shapes.

          Here's a demo that uses draggers for direct manipulation
          of a surface of revolution. 

-------------------------------------------------------------------------
NOTE:  You must be running the 5.2 operating system and have Inventor 2.0
       installed to run this demo!
-------------------------------------------------------------------------

Instructions:
    [1] setenv LD_LIBRARY_PATH .
    [2] ivview -q test.iv

    When ivview comes up, you should see a surface of revolution.
    Dragging the cubes changes the profile curve.
    Dragging the spheres changes the axis of revolution.
    Try clicking the right mouse and selecting 'hidden line' from the 
    drawStyle menu for a cool looking version.

Explanation:
    Step [1] sets the environment variable LD_LIBRARY_PATH to the current 
             directory.  Inventor programs (like ivview) will look here for
             DSO's of classes that are not 'standard' Inventor.  The files 
             given include one such DSO, RevoSurfEngine.so (see below).
    Step [2] Runs ivview, a program that reads in an Inventor file and 
             displays it on screen.

About the files in the directory:
    RevoSurfEngine.h   
    RevoSurfEngine.c++ - header and source files for a class of engine that 
			 takes an axis and a set of profile points as input.
			 Outputs points defining a surface of revolution.
    RevoSurfEngine.so  - Dynamic Shared Object for the RevoSurfEngine.
			 When ivview encounters a RevoSurfEngine in test.iv,
			 it will look in the current directory for this file.
    Makefile           - Makes RevoSurfEngine.so from the header and source.
			 (You can only do this if you have the inventor
			  developer option).
    test.iv            - An Inventor file containing a RevoSurfEngine,
			 draggers for editing the axis and spine, and
			 an SoIndexedFaceSet that displays the surface.

Inventor enables Rapid Development!!
    This demo took only 3 1/2 hours to write, working from scratch,
    start to finish.
