Examples archives history

[Mark Jones]

As fast as you're working Hitchhikr, we almost need an RSS feed! :bg

[hitchhikr]

Added Skybox_And_Camera.

(Only Examples.zip updated).

[hitchhikr]

I improved/cleaned up some examples.zip archive files.

[Mark Jones]

Oooh! What about support for GMAX/3dsmax and Rhino3d mesh data? :toothy

Was a sample Lightwave .obj file supposed to be included in the latest release?

[Siekmanski]

Cool stuff Hitchhikr !!!

I'll study OpenGL now. ( still coding in DirectX9 )
Thanks for all the nice examples.   :U

[Mark Jones]

I'm attempting to make some custom mouse pointer code for the OGL window, based on the DirectInput example. I tested the original example with MemProof and it reports that CreateBrushIndirect and CreateFont are not being freed. I am unsure how important this is, but adding the following to Fonts.asm seems to fix the font handle:

Create_Font_Bitmap   proc   Font_Name:dword, Font_Size:dword, Font_Weight:dword
    local    _Font_List:dword, hFont:dword

    ; Create the fonts
    invoke glGenLists,256
    mov _Font_List,eax
    .if eax != 0
        mov eax, Font_Size
        neg eax
        invoke CreateFont, eax, 0, 0, 0, Font_Weight, 0 , 0 , 0, ANSI_CHARSET, OUT_OUTLINE_PRECIS, CLIP_DEFAULT_PRECIS, ANTIALIASED_QUALITY, FF_DONTCARE, Font_Name
        mov hFont,eax
        .if eax == 0
            invoke Destroy_Font, _Font_List
            xor eax,eax
            ret
        .endif
        invoke SelectObject, g_window.hDC, eax
        invoke wglUseFontBitmaps, g_window.hDC, 0, 255, _Font_List
        mov eax,_Font_List
    .endif
    invoke DeleteObject,hFont
    ret
Create_Font_Bitmap   endp


And the Framework.asm - CreateBrushIndirect:


Main         proc
...
    local   hBrush:dword
...
    invoke CreateBrushIndirect, addr _SubEditBrush
    mov hBrush,eax
    mov [ebx + WNDCLASSEX.hbrBackground],eax
...
    invoke Deinitialize
    invoke ChangeDisplaySettings, NULL, 0
    .if g_window.hWnd != 0
        .if g_window.hDC != 0
            invoke wglMakeCurrent, g_window.hDC, 0
            .if g_window.hRC != 0
                 invoke wglDeleteContext, g_window.hRC
            .endif
            invoke ReleaseDC, g_window.hWnd, g_window.hDC
        .endif
        invoke DeleteObject,hBrush
        invoke DestroyWindow, g_window.hWnd
    .endif
    invoke ShowCursor, TRUE
    invoke UnregisterClass, addr g_ClassName, g_window.init.application.hInstance
    invoke Flush_Event
FallBack:
    .if g_Error_Message != NULL
         invoke MessageBox, HWND_DESKTOP, g_Error_Message, addr g_WindowName, MB_ICONERROR or MB_OK
    .endif
    ret
Main         endp

[hitchhikr]

I fixed this already and a couple of other ones.
I'm working on an example right now so except an update soon with these two ones corrected.

[hitchhikr]

- Fixed a bug in the coordinates of the 2d bitmap fonts.
- Fixed a bug in DInput_Clamp_Mouse.
- Fixed some memory leaks.
- Added Sprites_Collisions.

Both archives updated.

[hitchhikr]

- Fixed an issue with 32 bits pictures in Targa.asm.
- Renamed Display_2D_Bitmap into Display_TARGA.
- Added Display_BMP.

(Both archives updated).

Hi Hitchikr. :) Couple issues, XP SP2
* display_bitmap.exe - black window, closes with asterisk sound
* sprites_collisions.exe - ditto
* vertex_array_and_wavefront_obj.exe - page fault at 00404386h

This is with EVE running, this shouldn't be a problem but who knows. :) I'll try without eve running later.

[hitchhikr]

I updated Vertex_Array_And_WaveFront_Obj in the examples.zip.

Make sure that the archives layout is as follow:

OglArchive
   |
   +- Examples
   |
   +- Media

The Media directory is located outside the examples one.
Also make sure you have the latest versions of both archives.

I don't know why it produces beeps, maybe there's a problem with an alert messagebox which is not displayed or something.

I'm using XP sp1.

[Siekmanski]

Display_BMP works fine on my computer "XP sp2"

Sprites_Collisions didn't work

Couldn't find sprite1.tga and sprite2.tga
I did make some sprites on my own but they couldn't be loaded into the program.

Vertex_Array_And_WaveFront_Obj

Can you insert the fish2.obj  and the sprites in the next upload ??

All other examples are running O.K.

[hitchhikr]

These files are actually in the media.zip archive, there's 15 files in it, always make sure you have the latest one.

Beware of the browser's cache.

[Siekmanski]

Thank you Hitchhikr.

O.K. I did download the "media.zip" archive directly from your page
with all the files in it.   :P

The "Example archives content and urls" only have these two links:

http://perso.wanadoo.fr/franck.charlet/Common.zip
http://perso.wanadoo.fr/franck.charlet/Examples.zip

missing the media.zip

Now all examples work fine except "Vertex_Array_And_WaveFront_Obj.exe"

It assembles and links OK but when I run the file it crashes....   :'(

[hitchhikr]

My bad, i forgot to modify the link :green
The only required ones are Examples.zip & Media.zip

Where'n'when does it crash ?
