Construction Set 2.0 installed easily from its CD-ROM and consumed
about 65 MB for the complete install. The total install includes
demos, tutorial files, OpenGL, etc. The terrain modeling and
animation software is produced by Questar
Productions. World Construction Set is available for Intel,
Amiga and DEC Alpha computers as this is being written. Prices vary
for each platform. The Intel retail price is $835 and street price
will be less. Unix/SGI and Mac versions are promised. Check Questar's
page for details. For the Intel platform Windows 95 or NT is
required. RAM requirements are 16 MB minimum and of course more is
always desirable. Documentation consists of 2 manuals. The first
manual addresses the introduction and tutorials and is about 300
pages. The second manual is the reference manual and is about 400
pages. A mailing list is available and subscription procedures are
mentioned in the first manual. The first chapter welcomes the user to
the software. World Construction Set uses Digital Elevation Model
(DEM) files to create terrain. There a few different types of DEM
files. The U.S. Geological Survey (USGS) has one version. Several
USGS DEM files are on the CD-ROM. Terrain modeling software called
Vista Pro also uses a type of DEM file. DEM files are not essential
for terrain creation. World Construction Set allows the construction
of terrains from an internal fractal generator, terrains that are
drawn within World Construction Set by the user and grayscale images
in the .iff format. (Questar now has a downloadable update that
provides some support for 24 bit .tga and .bmp files.) World
Construction Set also allows the use of vector data to show rivers,
political boundaries, etc. (Since this review was published I have
been advised by Questar that they are working on World Construction
Set so it will import just about every file type around. ) There is
an overview and all the features are briefly mentioned. The next
chapter discusses how to use the manuals. The upgrade tips in
Appendix E address the needs of users upgrading from version 1 to
version 2. Appendix B addresses the needs of the geography novice. I
found this information to be helpful. It has been several decades
since I had a geography lesson. Even though I served 29 years in the
USN and traveled all over the world the refresher was helpful.
Appendix B addressed the divisions of the earth in degrees, minutes
and seconds. Longitude and latitude is discussed. A
brief description of all the chapters and appendixes of both manuals
is provided in this chapter. Mention is made of the demo images and
projects on the CD-ROM.
he
subsequent chapter addresses installation procedures. The next
chapter discusses getting started. DEM files are actually a series of
altitude numbers in table form. World Construction Set creates the
terrain then applies textures, sunlight, fog, clouds, etc. to create
a realistic appearing landscape. The
interface is deceptively simple in appearance. There are only 4
icons and 3 drop down menus. The
icons from left to right are for database, data operations,
parameters and rendering. They have bubble help labels. The project
drop down menu is roughly analogous to the file menu in other
applications. World Construction Set consists of 5 modules. These
modules work together and interrelate to each other. A change in one
module will be immediately felt in the others. The modules are
visible as separate windows/boxes within the World Construction Set
interface. All of the modules are accessible via the module drop down
menu. The parameters drop down menu is for loading and saving a
variety of parameter information. The next several pages of this
chapter have brief descriptions of the various modules and images of
the modules' interface and dialog boxes. World Construction Set does
not have an auto save feature so saving projects must be done manually.
he next
chapter is tutorial one. First the canyonfly.proj file is opened.
Then the modules drop down menu is accessed to display the map view,
parameters and camera view modules. At
this point I realized my 800 X 600 display wasn't going to cut it. I
could not display all the modules at the same time. I increased my
resolution to 1024 X 768 which resolved the problem. (I was advised
by Questar that each window can be reduced to an icon which
eleminates the absolute necessity for the higher resolution. One
of their employees told me he runs it all the time on a lap top
without any problems.) After the modules were loaded, the status log
window changed accordingly. The cam view window has the cam view
control box associated with it. The cam view control box has several
icons across its top. They all have bubble help labels. When the interaction/OpenGL
button is selected, the cam view window changes to provide a solid
image view of the terrain. The cam view window can be changed by
dragging the mouse across it. The mouse speed is set by a mouse speed
slider. It is a good idea to use a slow speed at first or else a
small drag will cause a huge change and the user may get lost. The
autodraw button provides access to some features that are mostly
optional depending on the speed of the computer and whether or not
OpenGL is used. The manual has a chart that shows recommended
settings for slow, faster and really fast computers. I used the
really fast settings on my Windows 95 133 MHz Micron with 64 MB of
RAM without any problems. Next the motion list window is activated by
clicking on the motion list button in the cam control box. This list
provides access to controlling the camera in the cam view window. The
camera altitude can be changed by dragging the right mouse button in
the cam view window.  Latitude
and longitude can be changed while dragging the left mouse button.
As the camera is dragged about in latitude and longitude, the yellow
camera area in the map view window also changes accordingly. The
yellow square represents the camera, the yellow cross is the camera's
target which is also called the focus point, the yellow circle is the
haze distance and the angled lines represent the camera's field of
view. The
camera can be dragged about in the map view window and the view in
the cam view window changes accordingly. The map view control box
provides some information and also some control. Latitude and
longitude information is displayed at the bottom of this box that
shows where the mouse is located on the map view window. A click on
the map view window will display the altitude and some other
information. The map view control box has 2 drop down menus on it.
The style drop down menu provides access to single, multi, surface,
emboss, slope and contour display styles. The
color drop down menu provides access to gray, light gray, color and
earth. The tutorial then instructs the user to set up a gray embossed
map view. The tutorial then points out that World Construction Set
will render a preview in the cam view window when the ecoshade
preview icon is clicked in the cam view control box. After the cam
view window renders, the diagnostic data box opens. This box will
provide information about the just rendered image. A click on the
image is required at which time the diagnostic data box provides the
information you see in the adjacent image.(I have been advised by
Questar that the information provided in the diagnostic data box is
information pertaining to the pixel that has been clicked on.)
he next
tutorial has the user create a new project from scratch without using
any DEM file. The new project dialog box opens and allows the user to
type in a name for the new project. An existing project can be
cloned. There is access to the windows

explorer provided via the small floppy looking icons at the right end
of each line. Once
the save button is clicked a subdirectory is created in the projects
directory with the name the user typed in. The camera view and map
view windows are black since there is no data. The are several ways
to obtain data however this tutorial procedure requires that the user
generate a fractal terrain using the fractal terrain generator. This
generator is accessed via the windows drop down menu in the map view
window. The generator has several controls which are explained in the
reference manual. For some reason I could not find any discussion of
the filter controls. (I have been advised by Questar that this
feature was added after the manuals were published.) Next the auto
button on the map view control box is clicked and the terrain is then
displayed in the map view window. Then the defaults button is clicked
on the parameters module. The ecoshade preview icon is then clicked
to see what the terrain looks like. The next step is to clone the
existing project. The
project/new dropdown menu is selected and the new project dialog box
opens. This time the user clicks on the file open icon at the right
end of the clone project line. The MyProject1 project file is
selected and MyProject2 is typed on the new project line. This
enables World Construction Set to use the DEM files created with the
original project yet have a separate project name and directory thus
allowing the use of different color maps, depth maps, ecosystems, etc.
orld
Construction Set has a unique in my experience opening option when
launched. Each time World Construction Set is launched the version
dialog box appears with 2 options available. A
click on the resume button will load the last project worked on at
the point where it was when World Construction Set was closed and a
click on the OK button will take the user to a blank screen with
nothing loaded. The curious thing about the resume feature is that
the project did not have to be saved. World
Construction Set will take the user right back to the point the user
was at even if the project wasn't saved. This could be very handy if
the user closed World Construction Set without remembering to save
the project first. The project drop down menu has a preferences
selection available that will launch the project preferences dialog
box. There is an option available for load on open which will load
the last project worked on however it loads the project from its
saved point. Next the MyProject2 project is cloned to MyProject3.
