Hexangular city.
Hexangular city, closer.
Hexangular city, even closer.
This QBasic program was written by me in around 2003. It parses scene definition language and creates 3D world based on it. Result will be in a wavefront obj file, witch can be then visualized using external renderer. Basic concept of defining scene is: Simple and primitive objects are created on point and polygon level. More complex ones can be created my combinig already existing ones, while applying various transformations on them. Objects with all its subobjects can be rotated, flipped or resized omong any axis. Generator has built in cache for data input and output to minimize file access.
I converted these 2 generated cities also to Blender format
so you can explore them interactively :)

System requirements
===================
DOS (6.22 preferred)
QBasic (4.5 preferred)
Installation
============
* Unpack ZIP file in any folder.
* update include path inside bin/3dparse.bas
Running program
===============
Make sure you have QB binaries in your PATH.
Execute bin/city1.bat or bin/city2.bat to generate example citys.
After parsing is finished appropriate *.obj files will
appear in the bin directory holding generated scene.
Visualize scene with your favourite renderer.
(3D Studio MAX or Nugraf 3D rendering System will do)
Directory layout
================
bin
3dparse.bas 3D generator main executable
city1.3d city with square-like buildings
city2.3d city with hexangular buildings
result.mtl shared material library
*.bat quick launch scripts
doc manual
include 3D objects used to compose the scene
Scene description language
==========================
(read examples...)
here - defines new segment
p x y z - defines new point
f p1 p2 p3 p4 - defines new polygon, p4 may be unused
warn message - displays warning message, and wait for key
end - terminates parser
mtl material - selects material
mtlrnd material ... - selects random material from list
obj object xz45 xy20 x+3 y*2 - includes sub object, can be rotated moved
or resized,
across X Y Z. If object name begin vith ~
then it will be loaded from current directory.
if object name ends with ~ then object will
be parsed directly from file, and not chached,
to allow loading of greater than 500 lines
files.
rnd p^1^2^3 p^7^2^1 - select random command to execute, ^ will be
converted to spaces.
# whatever text - comment
out file - specify output file name, must be first command
set variable contents - set variable contents, variable must be
number, contents can be string. max variables
is 100. first is 0.
anycommand %1 anything - inserts variable 1 contents info line
cmp flag string1 string2 - compares strings, and inserts TRUE to flag, if
they are equal, else inserts FALSE. max 9 falgs
,0 first. Each subobject has its own flags.
?flag anycommand - executes command if flag is true.
exapmle: ?3 obj car z*2 xy45
dum - dummy function, does notheing
