RE: [Plib-devel] new viewer example

[Fay J. F C. AAC/W. <joh...@eg...>]

Bram,

	I've looked at the "pview.cxx" file, added a project file, and
updated the workspace file.  I made a few changes to the source code to
allow it to compile without warnings under MSVC; you will probably want to
look at them.

Subject: [Plib-devel] new viewer example

Hi there,

examples/src/ssg/viewer/viewer.cxx has a non working orbit function.
I think it's a HPR vs Quat issue, so that you can't orbit directly
overhead of the model.

When I started out fixing this, I noticed that viewer.cxx is quite
complex, and not as lean as it could be.

I've added a new viewer sample (pview.cxx), with the following benefits over
viewer.cxx

- orbit works properly (with what I call a virtual ball interface a la
perfly)

- mean/lean/clean (appr one 4th of viewer.cxx size)

- better suited for instructional use for newbie ssg users due to smaller
code.

random notes:
-It was tested on linux and irix.
-I did not adapt the win32 project file.
-I left out the freeglut include hack: i don't see why this is req'd:
  I use freeglut myself, but it is simple available as GL/glut.h

   bram
