OpenB3D - Blitz3D for GLBasic

[bigsofty]

Hi,

This is my wrapper for OpenBlitz 3D.

See "Air.app.rar" for .exe demo.
See "OpenB3D.rar" for lib source.

Have fun!

Readme for the GLBasic wrapper OB3D

This version is an alpha.

To install the extra compiler stuff that the lib requires...
1) Since this messes with your compiler dir, back it up (I just zipped the Compiler dir)

2) Download http://www.glbasic.com/files/headers.rar and decompress the compressed 'compiler' folder into your GLB compiler folder, overwrite any files of prompted.

3) Decompress the "platform.rar" folder, from the attached archive, into your GLB 'compiler/platform' folder, overwrite if prompted.


To configure your OB3D project settings...

1) Open your project options

2) Set "cmp" command line option to "-I"<my project folder>\OpenB3d 0.35_src\src" -O3" (Without start and end quotes)

3) Set "lnk" command line option to "-llibglu32 -lGLee" (Without start and end quotes)

4) Make sure your Graphics res/Hz match your OB3D "Graphics" command parameters.


Note: Make sure your project has OpenB3DLib.gbas in it for the OB3D command imports.

That's basically it!


There is a demo ("air") project, just remember to change the "cmp" option to match your own path to the "OpenB3d 0.35_src" dir. Best way to see how this works is to get this project working then examine the options.


OK, OpenB3D ( http://sourceforge.net/projects/minib3d/ ) is an open-source Obj C -> C++ conversion of miniB3D/iMiniB3D by angros47 over here( http://www.freebasic.net/forum/viewtopic.php?t=15409&start=0 I'm Veggie there BTW!) on the FreeBasic forum.
Its basically Blitz3D for OpenGL, so you can load .B3D, .3DS files directly. It so closely matches Blitz3D, you can use the manual for Blitz3D! It has full internal quaternion support, so no gimbal lock, an entity system, ROAM landscape object, an internal boned animation structure, really nice sliding collision support (Coldet Lib I believe) and other bit-n-bobs.

I converted it for my own use, and that is, I intend to get it running on iOS/Android again as most of the lib is VBO/OpenGLES backward compatible. Its a single pass lib, so in many ways the GLbasics internal 3D lib is better for your needs if your require two pass features (shadows for example). It 'should' work on Linux off the bat, I can't test it. It has no external dependencies to speak of. The Glee/Glu extension support is only needed for the windows version. In theory getting it to run on OSX should be a breeze too.

GLB 2D works fine, 3D seems to have a problem with frustum clipping (neg Z is fine, positive "Z" is clipped), still looking into getting them to play together though.

All the C files were altered using the GLB editor, which I have discovered works as a rather fine C++ source editor. That is the point of not using static libs yet is to allow the source to be on hand and modifiable right within the GLB IDE, compilation is a breeze(remember to double click the Debug icon though, to wake up incredibuild! ) as its part of the project. So this is a dev version of the finished project. I am not a C programmer so any tips in this area will be very appreciated. I am only responsible for the wrapper and all lib source questions should be directed towards Angros(he's a very approachable guy BTW!). If you can, contribute to this worthy project with source fixes/updates, then please do.

Couple of bugs to squish yet, its an alpha remember, oh and your media needs to be in the same dir as the app .exe for now too.

Thanks go to...

Si Armstrong, angros47, Gernot, Schranz0r.


Ian Thompson(aka Bigsofty/Veggie)


P.S. If Gernot fulfils my request for default IMPORT param values, this lib can be simplified a lot further. Also an option to turn off incredibuild for editing C source, would be great too.

OPENB3D ?

WTF?!

[bigsofty]

Its really a conversion of iMiniB3D (see http://www.freebasic.net/forum/viewtopic.php?t=15409&start=0). Its not the full Blitz3D engine (BSPs for example are noticeably missing ) but 90% of it is in there and working.

[ampos]

Is this only for Win or any GLB target?

[Marmor]

 
you are a mad dog 

[bigsofty]

Thanks Marmor, I think!

Ampos, it ready for Windows and Linux(untested), it 'should' work, with some very small modifications, almost anywhere as its pretty platform neutral code.

[Schranz0r]

I like the mix between GLB and B3D !

Awesome work!

[bigsofty]

Thank you. Has one one tried a Linux build yet?

[Marmor]

no linux here .
we need ios android and webos !
who can ....

[blackway]

bigsofty, thank you very much for your work !
It's great!!!

[bigsofty]

Glad you like it Blackway!

Big Softy, it´s really impresive. I take a look a another 3d engine, make for Blender, I think it´s called game Kit, it´s are in Google, and Use the Irricht or another engine(don´t remenber the name), it´s free and can use on iPhone, and now I look a developement about Android, the quality it´s very good.

I think this can be a good option, but well it´s a lot of work.

But the wrapper it´s awesoming, I hope this can use in mobile devices, if not, well for make PC games can be vey, vey usefulll, thanks Bigsofty.

[bigsofty]

Your very welcome Mentalthink.

I hope to start to try and get it going on iPhone as soon a Trucidare and Gernot release the Win32 iOS compile feature(I have no dev account at the moment), Android will hopefully follow after.

Ok Bigsofty, this can be absolutly awesome, I stay hallucinated the thing that made the Masters of GLbasic.
Simply impressible, and admirable yours knoledges.
