2D/3D plane-wing model (with DDE transfer) , Rubik's Cube and bitmap viewer
program , wireframe model and included images
(c) U. Penski 2003 - July-04-2008

what is new in Version 1.26 ?



- demo of interactive Rubik's cube display
- direct slice selection with mouse

installation



- For full functionality of 'viewer' you can additionally download and unzip the 60 kBytes package 'ddecli.zip'
(containing the file 'ddecli.exe' which has to be put into the same directory as 'viewer.exe') e.g.
from
http://members.lycos.co.uk/penski/ddecli.zip
or
http://penski.tripod.com/ddecli.zip

- start 'viewer.exe'


features



- demo of interactive Rubik's cube display
- graphical highlighting of currently selected slice
note: in the demo version only 2 coordinate axis can be used for sliding

- plane model:
- displayed texts are integrated in the "viewer.dat" file ( in the newly created "[text]" section )
Besides that the '.dat' file format defines a "[wing]" and a "[structure]" section
and allows "varname=value" entries for [wing] .
Don't change these section names or the order of variable entries within a section !

- angle-value subwindow :
- "mouseover" reaction of its "close" button
- the window can be moved with mouse horizontally and vertically

- virtuality support for prismatic 3D screen surfaces

Profile usually shaped as displayed with rounded edges
and designed for a 1 pixel width of the image-stripes (labelled 'a' and 'b') that are used to display the
2 partial images A and B of a 3D object.

- red/green glasses (started via the 'Options' menu)
- electronically alternating 3D glasses (see 'help'-menu) with
- 3D image display (2 sample 3D images have been linked into the file 'viewer.exe' ;
the 4 corresponding partial BMP images (labelled 'art1' to 'art4') can be changed e.g. via
the tool "workshop.exe" ( available from Borland / www.Inprise.com )
- parallel port signal generation (start parameter 'p' ; see program's help menu)

- external angle viewer 'ddecli.exe' [ connected via Dynamic Data Exchange (DDE) ]
with local popup menu (activated by right mousebutton)
- dialog for setting the colors of the 2 objects (selected via button)
- URL copy option (--> 'help' menu)
- doesn't request a Windows timer


current wing-model limitations


- the front wing doesn't have the ideal profile for a maximum lift-force
- only 1 wing-segment is displayed ; a complete wing would consist of several combined segments
with different width and length properties depending on the specific segment position within
the whole wing


history


- the displayed wing concept has been inspired by the Concorde's (BritishAirways / Air France)
steering problems at low speed when thrust is reduced e.g. due to engine failure
(see e.g. http://uuhome.de/penski/news.htm )


program limitations


- the 2 integrated sample 3D images have not been photographed with a perfect eye-distance
between the 2 camera positions and/or equal orientation of the camera.
Colour depth and image size have been reduced to keep the package file-size low.
The images should be replaced by the user to get a *real* 3D visual impression.


known bugs



- the displayed color in the dialog box when another "object" button is pressed
- slightly wrong position of rotation axis when sliding the cube
