Demo version (as of 27Nov1991)
------------
This is the DEMO version of RayDance 1.0. It is fully functional in
all areas but two:
o Aproximately every 15 minutes of rendering time a requestor
will appear prompting you to click to continue rendering.
o The total number of polygons and spheres in a scene is limited
to aproximately 1400.
File list:
---------
Several files are present on this disk. All files ending with a .lzh
are archives. To use them you will need to decompress them using lharc.
o README
o COPYRIGHT
o demo.lzh
o demo_nofp.lzh
o scripts.lzh
o textures.lzh
o objects.lzh
When unarchived (with lharc) the following files are will be found:
o demo.lzh
RayDance.demo
RayDance.demo.info
o demo_nofp.lzh
RayDance.demo.nofp
RayDance.demo.nofp.info
o scripts.lzh
misc. script files
o textures.lzh
misc. texture and bump maps
o objects.lzh
misc. objects
Two executables are provided:
o RayDance.demo - this version requires 68020/68030 and 68881/68882
hardware.
o RayDance.demo.nofp - this version will run on any Amiga with at
least 1 meg of ram. Note however that most scripts will require
more ram.
Other files
o RayDance.setup - a RayDance default parameter file for hard disk
based systems.
o RayDance.floppy.setup - a RayDance default parameter file for
floppy based systems.
Hard-disk Installation:
----------------------
Create a drawer (directory) named RayDance_Demo on your hard disk
for the RayDance files to reside in.
Within this drawer create three sub-drawers:
o Scripts
o Textures
o Objects
Place the script, texture, and object files into the appropriate
drawers.
Copy either of the two executables into the RayDance_Demo drawer.
Copy RayDance.setup to the s: directory.
Floppy Installation:
-------------------
Format two floppies and label them
o RayDanceDemo:
o RayDanceDemo2:
On the RayDanceDemo: floppy create the following drawer:
o Scripts
On the RayDanceDemo2: floppy create the following drawers:
o Textures
o Objects
Place the script, texture, and object file into the appropriate
drawers.
Copy either of the two executables into the RayDanceDemo: disk.
Copy RayDance.floppy.setup to RayDanceDemo:RayDance.setup
Running RayDance from workbench:
-------------------------------
Open the drawer (or disk) containing the RayDance files. Double
click on the RayDance.demo icon. After a few seconds (floppies will
be much slower) the RayDance command window should appear (if your
workbench screen is interlaced both the command and message windows
will appear).
Check the texture path and object path strings.
Paths for hard disk systems:
Texture path - Textures
Object path - Objects
Paths for floppy disk systems:
Texture path - RayDanceDemo2:Textures
Object path - RayDanceDemo2:Objects
If the path strings do not specify the directories where the texture and
object files are located the example scripts will not run.
Use the PRESETS menu to select the 160x100 size.
Click on the script file disk icon on the command window. A file
requestor should appear. The directory should be Scripts and the
supplied example scripts should be displayed. Select the script file
'grail.art' (RayDance scripts end with a .art suffix by convention) by
double clicking on it or click once on the file name then click the USE
gadget.
Click on the RENDER gadget. The message window should come to the
front and show some messages. After a short while the preview window
should become active and you will see the picture RayDance is
generating.
The file artwork.iff24 should appear in the ram disk. This is an
IFF24 file and may be displayed by any program that supports IFF24
format.
Running RayDance from the CLI:
-----------------------------
RayDance REQUIRES A STACK OF AT 25000 BYTES. Use the STACK command
to check the current stack space. Type
STACK
if there are more than 25000 bytes you are ok. If not type
STACK 25000
to enlarge the stack. If there is insufficient stack space RayDance
will tell you so on the message window.
To start RayDance from a CLI you should cd to RayDance's directory
(drawer) then type
RayDance
RayDance should then load after proceed the same as if it were being
run from the workbench.
Help system:
-----------
Help for the user interface gadgets and displays can be obtained by
activating the window you are interested in, moving the moush to point
at the object of your curiosity then press the HELP key.
Alternatively use the HELP item on the project menu.
Script syntax:
-------------
There isn't space here to cover the script language completely (the
manual for the 'full' version of RayDance is over 200 pages) but here
are some fundamentals:
Comments start with an exclamation mark and extend to the end of line.
Input is free-form. Statements can be on one, two, or more lines
with an arbitrary amount of white space (blanks, tabs, newlines)
between each component of a statement.
Variables: Variables can be one of the following types,
Integer, Real, Complex, Vector, and Matrix
Values:
Examples of integers: 1 4 12345 -784
Examples of reals: 1.0 2.98 -0.0029947 .3 -.05
Examples of complex: 1+2i 4-6i -.2+1.7i
Examples of vectors: [1,2,3] [.2,.55,100.983]
Examples of matrices: [1,2,3,4,5,6,7,8,9]
Operators:
+ - * /
% (modulus)
. (vector dot product)
# (vector cross product or vector transformation by a matrix)
| vector | (vector length)
Basic scene elements:
Sphere, polygon, or quadric surface
Internal object generation:
LATHE (surface of revolution)
EXTRUDE
MESH (2d array of points interconnected by triangles)
TREE
LANDSCAPE (terrain generator)
MANDELBROT (mandelbrot mountain generator)
Memory usage:
------------
RayDance is not a small program and 3d graphics tend to require lots
of memory anyway. You will need a MINIMUM of 1 meg ram to operate
RayDance. If you have only 1 meg and you getting out of memory errors
then try the following:
o If the render starts ok but fails part way through try changing
the picture file location from ram: to a disk.
o For especially tight memory rendering the preview window can be
disabled freeing up the memory required by the 320x400 HAM window.
Example pictures:
----------------
Also included are HAM version of some pictures created by RayDance.
Thankyou and happy rendering:
----------------------------
You should now be started using the demo version of RayDance.
Experiment with picture sizes. Try the antialiasing. I hope you
find the unique capabilties of RayDance useful.
Many thanks from
