- ------ meddle source code read me ---------------
-
- WARNING: USE THIS SOURCE AT YOUR OWN RISK! THE AUTHOR IS NOT
- RESPONSIBLE FOR ANY LOSS OF DATA OR OTHER DAMAGE CAUSED BY USE
- OF THIS SOURCE CODE!
-
- ------ ramblings ------
-
- I haven't look at the bulk of meddle's source since a few
- weeks after the qtest, but some tweaking was done in march i think.
- I will warn you that it isn't a pretty sight.
- Keep in mind that most of it was written in about a week.
-
- I kept telling my self that I would clean it up and release it.
- Well I am releasing it.... but the clean up is not there.
- You may find it hard to follow. That is too bad.
-
- The version of source is slightly different from the released
- version of meddle (1.0). This is because I added some gouraurd
- shading, the ability to take screen shots, and a faster 2d to 3d
- transition. And I fixed the mouse control in 2d mode a little I
- think.
-
- My intention was to create a simple GUI and make a 3d editor. Well
- I have a simple GUI, but its source is just as ugly. But I did learn
- a little about making a GUI. SO... I'm not gonna do a DOS MedDLe
- editor with a nice GUI because it was taking too long, but if someone
- needs some suggestions on gui developement, I may be able to suggest
- a few things if you are new to this sort of stuff.
-
- Also I hope someone ports this to linux, since I've had a few
- questions about that...
-
- LASTLY, there are some bad programming techniques in this source as
- well as some errors which really don't hurt anything. Too bad.
-
- ------ the files ------
-
- This is all i'm gonna say about the contents of the files,
- but you can email me if you have a question:
-
- makefile :: it's the make file (duh)
- mdl.pal :: the palette for quake (comes with meddle)
- mdl.map :: color map (comes with meddle)
- mdl.cfg :: config file for program (comes with meddle)
- mdl.cc :: the main program, reads command line, cfg file, etc.
- it now also has a small help section
- mdl_io.cc :: read/write mdl file, set up 3d data
- mdl_2d.cc :: All the 2D editing and displaying things
- mdl_3d.cc :: All the 3D editing and displaying things
- bg_grx.cc :: My graphics routines converted to grx with a lot of
- unused and redundant stuff. A lot of 3dgpl stuff pasted
- in there.
- bg_mouse.cc :: my mouse routines (yuck)
- bg_grx.h :: header file for graphics and
- more 3d junk
- bg_mouse.h :: header file for mouse stuff
- mdl.h :: header file for main program
- cwsdpmi.exe :: dpmi environment (comes with meddle)
-
- I bet most of you are reading this because you want to add texture
- mapping to something. Well, here is some help. You'll have to look
- at stuff towards the end of bg_grx.cc, you'll need to cut and
- paste alot. It doesn't do proper volume clipping either. You also
- should look at mdl_3d.cc since that is where the meat is. It is
- completely un-optimized. If you don't understand the 3d format, it
- is similar to that found in the book by Allen Watt ( i think that's
- his name) on 3d graphics. In the main loop I convert all points
- to the eyeball (camara) coordinate system, sort the sides, back
- face removal, then draw them. That's it.
-
- The texturing routine is a little different from 3dgpl, it just
- uses bilinear mapping instead of perspective corrected.
- Gouraurd shading has been added to the texture mapping (like
- quake).
-
- Lastly, I included 3ds2mdl.cc which kinda works. It is a program
- which reads 3ds files and saves them as an mdl file. It only reads
- one object and is in the experimental stage. I did make some quake
- models with it though. You just have to keep the number of polys low.
- And use MedDLe to do the mapping. The makefile for it is called
- makefile.3ds. This may be of some help to someone. Figuring out the
- 3ds file format wasn't the easiest thing to do with the docs I had,
- (and I didn't have 3ds!), so if you release a converter of some sort,
- please give me some credit. The hard part is done, you just need to
- fix some things.
-
- Note i didn't fix this to work with the new version of the models.
-
- ------ compiling ------
-
- You should be able to compile this stuff as is with DJGPPv2 and
- GRXv2. I will tell you right now that I am one of the best source
- code thieves. But I do give credit where credit is due. Most of the
- 3d code was adapted from 3dgpl (get it at x2ftp.oulu.fi) as stated in
- the meddle read me. If your good enough to understand the stuff your
- stealing, then fine, it saves time. That's why meddle source is here.
- If you can make heads or tails out of it, it may help you make
- your editor. Take what you want, just give credit to whom you feel
- deserves it.
-
- note: the 3ds2mdl might not compile (or even work). But it should, I just
- haven't tested it for some time and it might be an old version.
-
- oh, and just type 'make' to make the program. :)
-
- -------- LAST WORD ------
-
- The meddle project IS NOT DEAD. It's just that I don't have much time
- now a days. I am learning vc++, and will continue MedDLe in windows.
- I also plan to make it a real 3d editor. If time permits there will be
- some quake map editing features like monster placement and stuff. For
- you dos and linux guys, I give you this code :)
