PREVIEW: GFA VEKTOR by Richard Karsmakers
GfA Systemtechnik (Heerdter Sandberg 30, D-4000 Düsseldorf 11,
West Germany, Tel. 0211/588011) has recently launched some new
software, of which two are "GfA Draft" (a CAD program written
in Pascal) and "GfA Vektors". While I was installing my
wordprocessor to write this article, I heard that GfA
Systemtechnik has also launched a program called "CAD Campus" in
the Dortmund show last Saturday, Februari 21st. But since I have
no reasonable knowledge of CAD, I wanted to confine this article
to "GfA Vektors" only.
The program is written entirely in GfA Basic and I must admit it
is very fast indeed (but all 3D routines have been written in
machine language anyway, so that's not strange at all). It is
published by GfA Systemtechnik (it is written by Jürgen Abel) and
it sells at DM 149,-.
In fact, it is a program that allows you to write 3D graphics
routines for use in own program - demos or games or whatever. The
package includes an extensive graphics editor that lets you
design 3D shapes, later to be animated and included in your own
programs by the use of ready-to-merge routines and modules. Some
of the features of the program include:
- It is possible to define any clipping window you want
- You can work on two or three pages
- The graphics can bce ORed or XORed
- Coordinates are automatically adapted to the resolution you're
in - something that's designed using low res will also work on
high res, etc.
- Data is given through simple Basic arrays
- You can work with a maximum of 1024 points, 1024 lines and up
to 32 objects
- Angles can be specified in 1 degree accuracy
- Enlargments can be made: from 1/64 to 8 times actual size
- X-,Y-and Z-rotations can be specified and given a direction
- The program works on color-as well as monochrome monitors
This program seems to be a very nice programming tool, somewhat
like our own Scroll Message Editor but with a different target,
more complex and more difficult. I was planning to make a nice
demo using GfA Vektors, but unfortunately we got into some time
trouble finishing ST NEWS - as usual - so that might eventually
be published in the future (or maybe not at all).
Giving a 'game' rating wouldn't fit this program, so I'll try to
give you a bit of oral impressions of mine; I think the program
is very well written, and it definately covers a gap in the
market. It is very useful and its price is reasonable (in fact
too much when seen in the light of the 'editorial' this time),
and it is very user-friendly. The Germans never cease to amaze me
of the fact that nearly everything can be done in GfA Basic...
The text of the articles is identical to the originals like they appeared in old ST NEWS issues. Please take into consideration that the author(s) was (were) a lot younger and less responsible back then. So bad jokes, bad English, youthful arrogance, insults, bravura, over-crediting and tastelessness should be taken with at least a grain of salt. Any contact and/or payment information, as well as deadlines/release dates of any kind should be regarded as outdated. Due to the fact that these pages are not actually contained in an Atari executable here, references to scroll texts, featured demo screens and hidden articles may also be irrelevant.
