|Using Second Reality.|
Second Reality is an OpenGL based application and
runs under IRIX on SGI Machines.
in the command line the user can specify a desired *.sr file
or several models in *.dat or *.dat.Z format.
A texture can also be specified.
On execution the user gets a large Drawing Area
and Some control menus.
The Drawing Area is resizable, and changing its size
will affect the size of the rendered image.
The user can transform 3D objects in space.
He can translate, rotate or scale any of the objects or
all of them at once. He can group some objects into one,
or ungroup a complex object to its ingredients.
objects can be added or removed from the scene,
object attributes like: color, fineness, appearance etc'
can be manipulated.
At all time, one of the objects is selected.
The Selected object is marked with bounding box and all
transformations and modifications will be applied on it.
the user can choose to transform all objects altogether.
in that case a bounding box around all objects in the scene
will indicate that choice.
Textures in *.jpg, *.ppm, or *.rle can be chosen to make the
stereogram. many paprameters control the resulting SIRDS image,
and are explained in detail in
The user at ant time can save a constructed scene and all relevant
parameters and variables into an *.sr file.
Once loaded an *.sr file will reconstruct the entire system status
as in time of save, including all models, texture, attributes,
SIRDS parameters etc'.
Four differend kinds of images can be rendered by Second Reality.
1) Shading model of the scene.
The Control Menus are:
Each control menu has a 'Fold Menu/Unfold Menu' button.
The user can use these buttons to unfold a menu in order
to use it, or fold it back when it is unused or in the way.
