- Introduction
- ------------
-
- This program will convert GFA Raytrace files into Spectrum 512 files.
- GFA Raytrace uses it's own file format which until recently was a
- complete mystery. GFA Raytrace is capable of generating some very
- stunning raytraced images, but due to it's file incompatabilities the
- output was all but useless in my mind. GFA does not include any printer
- or file conversion utilities with GFA Raytrace. Well, the only way to use
- your newly created images was to wait for someone to come along and write
- a conversion utility. I was waiting myself! Well, if you are one of
- those people waiting for such a program then your wait is over, as you
- have probably discovered perphaps the only GFA Raytrace picture converter.
-
- Now let's get serious for a while. The first point I want to make
- is this. Just because I have released a conversion utility of this nature
- doesn't mean you should give up on GFA Raytrace being updated. I urge
- you to write GFA and ask them to update the program. Tell them what you
- want to have added and/or fixed before it's too late. GFA seems to be
- ignoring the program and the people who purchased it. One particular
- person who I will mention is Nick Smith, he has been trying to get the
- needed documentation for this type of conversion utility for some time.
- Without Nick Smith you wouldn't be reading this docs file, he was the
- one who urged me to finish the program. As it turns out I managed
- to figure out the file format without the help of GFA, so they might
- as well release the specs now as it is no secret anymore.
-
- Included in the package is a text file written by Nick Smith. This
- is the same text file that prompted me to contact Nick and I urge all
- GFA Raytrace users to read it.
-
- This documentation will focus primarily on the operation of this
- program; it's not intended to teach you how to create and/or read the
- picture file formats used by the program.
-
-
- This program is ShareWare!
- --------------------------
-
- Now, before you get to excited I must first tell you that my
- ShareWare adventures have be less then what I expected. That's not to
- say I havn't gotten any replies, I have, but I think the numbers should
- be a little higher than they are. In an attempt to over come the
- problem I decided to try an approach used by other ShareWare authors.
-
- The program you are about to use is somewhat less than perfect. That's
- not to say it doesn't work as advertised, in fact it does work as
- advertised but with one small catch. The Spectrum 512 pictures it
- outputs are not easily touched up in Spectrum 512, but look ok when
- viewed from a slide show. If you want to output Spectrum pics which are
- fully compatible with Spectrum 512 then you'll have to register the
- program. After registering, a full working version will be sent to
- you. I didn't want to do it this way, but I think it's for the best.
-
- If by some chance you are given or download a registered version of
- RayVerter (not registered to you) please forward it me stating the source
- of the copy or destroy it yourself! Thanks.
-
- All versions of this program are 'ShareWare', this means that if
- you decide to use it you're expected to pay for it. You pay for the
- commercial programs use, right? Why not pay for the ShareWare you
- use as well? Rememeber, ShareWare doesn't happen by accident. The
- author spent time writing the software and relies on your honesty
- as an Atari Computer owner.
-
- The registration fee is $5.00 ... or send what you think it's worth.
-
- If you do decide to use it, please send a check or money order
- in U.S. funds to...

-
- I thank you for your support! Please remember, if you want to see
- more ShareWare programs like this, you have to do your part and pay for
- the ShareWware programs you use.

-
- Using the program
- -----------------
-
- Runs in low or medium resolution only.
- Reads GFA Raytrace 'SUL' uncompressed files only.
- You must first uncompress the file you wish to convert. To do this
- you need to load GFA Raytrace and turn off the 'Compression' feature
- under the 'Status' option from the editor. Load the picture and
- then resave it and it will be uncompressed.
- Writes Spectrum 512 'SPU' uncompressed files only.
-
- To use the program either:
-
- 1) Install the program as an application on the GEM Desktop with a file
- type of 'SUL' and then save the Desktop information. Double-click
- on the GFA Raytrace 'SUL' file you wish to convert. The 'SUL' file
- you clicked on will then be loaded and converted. The 'SPU' file will
- always be written to the same directory as the source file.
- Example: Input> D:\PICS\ROOM3D.SUL
- Output> D:\PICS\ROOM3D.SPU
- After saving the 'SPU' file you will be return to the GEM Desktop.
-
-
- 2) Double-click on the program from the GEM Desktop. The file selector
- will appear so you can select the GFA Raytrace 'SUL' file you wish to
- convert. The 'SUL' file you selected will be loaded and converted.
- When it's done it will be displayed in Spectrum 512 mode. Press
- any key when you are done viewing the picture. An alert box will
- appear asking you if you want to save the 'SPU' file. You have three
- options:
- 1) Write the 'SPU' file to the default directory.
- 2) Use the file selector to save the 'SPU' file to a specific
- directory.
- 3) Abort the save.
- Once you've made your slection the program will save the 'SPU' file
- and cycle back to the beginning so you can convert another 'SUL'
- file. Selecting 'Cancel' in the file selector when prompted for a
- 'SUL' file exits the program and returns you to the GEM Desktop.
-
-
- These option are valid no matter how you execute the program.
- The 'SUL' file you selected will be loaded and displayed. This program
- converts the 'SUL' file in one pass. You can peek in on it's progress at
- anytime by pressing the space bar which causes the program to display the
- picture in Spectrum 512 mode. Leaving the 512 color mode on slows done
- the conversion! Pressing the space bar again shuts off the 512 color
- mode. Pressing escape aborts the conversion without saving. After the
- picture is completed a bell will ring. Due to the differences in the
- file formats it's possible the output picture won't look exactly like the
- input file. RayVerter attempts to retain as much of the original picture
- as possible, infact most pictures are pixel for pixel copies while others
- are slightly averaged.
-
- NOTE: If an error is detected all open files will be closed, and you will
- be alerted and return to the GEM Desktop.

- About the program
- -----------------
-
- This program was written with GFA Basic 3.6TTe on a stock Mega ST2
- with TOS 1.4 and a SC1224 color monitor. I can't say for sure if it
- will run on lesser or newer machines, but it should as long as the
- machine you run it on supports Spectrum 512. Since I wrote the program
- without any docs on the GFA Raytrace file format it's possible I over
- looked something important. If anyone has any scrap of info on the
- file format I would like to see it. Future version might read compressed
- GFA Raytrace files and perphaps write GIF files or other formats that
- can better retain all the colors. Please contact me if you have an docs
- on GIF, GFA Raytrace, or Spectrum you would like to send my way.

- User Support
- ------------
-
- If you have an idea for a feature or want to report a bug (if any)
- then by all means contact me. Please include the full name and
- version# of the program you are refering to. If your not a registered
- user I'll read your replies, but don't expect me to take you serious.
- On the other hand if you are a registered user I want to hear from you
- and I'll make an honest effort towards whatever is required.

- I'd like to Thank
- -----------------
-
- Nick Smith for urging me to finish the program and making me aware of the
- fate of GFA Raytrace.
- Trio Engineering for releasing the Spectrum 512 load/display modules and
- the documention needed to create such images.
- I'd like to thank GFA, but I cannot.
