Horde3D.bi is complete now and I added the Doc folder.

Joshy

[D.J.Peters]

I build a new version of the 3D engine and added a missing Terrain node.

Dynamic libs for Windows x86 and X86_64 are included.

Currently I build the lib for Linux X86 and X86_64 also.

Joshy

[D.J.Peters]

I build Horde3D as single lib (no more extra lib HordeUtil)
and added the util and terrain stuff to Horde3D.bi.
I added the Terrain API to the html docu also.
Libs for Windows and Linux included now.
Horde3D-32.dll
Horde3D-64.dll
libHorde3D-32.so
libHorde3D-64.so

... only with screenres ...

If it works with the OpenGL context from Screenres hat means something is wrong with your windows only stuff.

May be you create a none shareable OpenGL rendercontext inside of your DLL ?

If you create it with Screenres the OpenGL render context are shareable with oher libraries.

I tested Horde3D on Windows and Linux without any problems.

[D.J.Peters]

Chung do you tryed h3dutInitOpenGL(hDC) normaly you don't need it ?

Horde3D works with with any created OpenGL compatible* redercontext: FBGFX, FLTK, GTK+, SDL, QT 4/5, GLUT, FreeGLUT ...
(*) It used shaders so it must be OpenGL version >= 2.x, 3.x, 4.x

Code: Select all

#ifdef __FB_WIN32__

no, it does work well without changes with horde3D

it is alfakilotankgame.bas that doesnt work , i tryied alfakilotankgame with glfw too , it crashes idem

I know no one here used this modern graphic engine however I added some C++ code:
h3dutLookAt() h3dutSetDumpFile() h3dutSetDumpTitle() and a fresh build of my version of Tokamak physics lib.

I just downloaded your zip file and everything worked just fine. Thanks for all the work!
I feel like a kid in a candy store with libOpenB3D and now Horde3D.

As a note, hope this helps anyone else in the future.
I am running in Linux Mint 64 bit. I found out that when you place .so files in
/usr/local/lib
and you still get errors of it not finding the .so file when you run the program
you have to run this command in the terminal first: sudo ldconfig

ldconfig creates the necessary links and cache to the most recent shared libraries
