libOpenB3D Win32/64 Linux32/64

Postby D.J.Peters » Dec 13, 2018 10:30

I share my personal version of MiniB3D/OpenB3D with you I name it libOpenB3D.
I fixed some small bugs and changed all color arguments and added new stuff also.

I wrote "openb3d.bi" completely new.
All in #lang "FB" OOP style now

download a FreeBASIC package and some tests: libOpenB3D-1.25.zip last upload: Aug 31 2019
(openb3d.bi libOpenB3D-32.so libOpenB3D-64.so OpenB3D-32.dll OpenB3D-64.dll)

source code with Code::Blocks project libOpenB3D-1.25-src.zip last upload: Aug 29, 2019
(source code and pre compiled static libs of gLee are included Win32/64 Linux32/64)

I commented the most command's but not all 400 in the include file "openb3d.bi" !

Most commands was documented from BlitzBasic 3D (so far I know)
but the commercial BB3D site is down and was published as open source.

I found other places with documentations.

Thanks for this Joshy.

As a long time past user I've recently reacquainted myself with OpenB3D. It used to have quite a few bugs, are there any bugs in the latest version I need to be aware of?

New upload available (see first post)

I added some new commands (now ~400 before 324)
All new stuff marked with NEW: optional (new) arguments commented with NOTE:

I improved the shadow object with an optional second mesh argument.
compare file "shadow.bas" with "shadownew.bas"

I added many comments in file "openb3d.bi" read it or let it :-)

I improved many parts of the C++ source code search for !!! with your favorite IDE you will find more than 150 places with changes.

Wow this is some very nice work, and yes i did not know that the lipOpenB3d is so different from OpenB3D.
I need to study this one later, first this.

I had to change a line in your openB3D.bi

Code: Select all

declare sub      ScaleTexture   (byval _Texture as tTexture, byval fUScaleFactor as single, byval fVScaleFactor as single)

to

Code: Select all

declare sub      ScaleTexture   (byval _Texture as tTexture ptr, byval fUScaleFactor as single, byval fVScaleFactor as single)


The loadtexture function returns a tTexture pointer
I think this counts for more lines, RotateTexture, PositionTexture, ...

Joshy

Code: Select all

var craft = LoadMesh("fighter.3ds")
if craft = 0 then
  windowtitle "fatal error: loading 'fighter.3ds'"
  beep:sleep:end 1
end if

Hi Joshy, long time since we last messaged on the forums.

I am on linux mint 64 bit and downloaded your zip file.
I am able to compile your test program FluidBlob.bas, but when I try to run it
I get a message that it can't find the libOpenB3D-64.so file.

I placed both the .a and .so files in my freebasic lib folder under /usr/local/lib/freebasic/linux-x86_64

Can you tell me what I am doing wrong, thanks.

delete the copy of the *.so and *.a file you made before
and copy only the *.so to the right library folder (32/64-bit)
maybe:
/usr/lib/
or
/usr/local/lib/
or
...

Yes, thanks. Putting it in usr/local/lib did the trick.

Also thanks for your work on this and all your other prolific work on other libs.

I am trying this code (on Linux), but there seems of be a bug with loading things.
LoadSprite("file") does not return 0 when the file does not exist. Same for e.g. LoadBrush("file").
The examples (e.g Shadow.bas) test for 0 as failure, but this never seems to happen.

Errors are displayed, but not by the example itself.

Linux 32 or 64 bit how do you run it from console or from IDE like geany ?

I tested it on Windows XP, Windows 7, Windows 10, Linux Slackware 32-bit and on Ubuntu 64-bit and have no problems here !

Joshy

EDIT:
The relativ path is ./media/ and not ./mediaX/ as you posted ?
If a file can't be loaded the object are created and the pointer to the class are returned !

Ok I see:
if a file can't be loaded the class self are created and so no NULL is returned I will lock for a workaround !
