[cadcdev-tiki] [Tiki-win32] OGL-UVN camera system

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

 Hi again,

 Im going on with the development of my shmup project for Win32/DC under =
Tiki, i made great advances about the engine with the help of the =
environment:

---
 Im having a great problem, so if this letter is to large, please read =
the last paragraph. Thanks
---

 First of all, im interested in backup my project under sourceforge =
because everyday i fear to lose everything from my computer. Could =
someone give some directions to do it, please?

 Regarding the project, as i said everyday im more impressed with the =
whole implementation of the Tiki dev: Everything i have already done in =
my engine, is better implemented so my engine is more like an equivalent =
layer of the Tiki one, with things like object count references, hid =
callbacks, HW timers, threading!! and such... I mixed with the use of =
the minixml lib and I hope "everything" could be parametrizable from the =
XML trees and files... I have already put an fps counter with a font =
texture under OpenGL which works fine (60 fps on Windows and DC!!!)... =
So now its time to start with the graph scene (i was doing my own, but i =
will use the Tiki one again!!!).

 By the way, i did another change on the windows callback function: On =
the switch(msg) part i added some breaks for the WM_KEY's which were =
screwing my HID callback system!! I dont know if anyone else has been =
affected with the problem...

 Ok, then about the graph scene system: After checking the DCBlap =
sources and discovered the gs and the Generic Menu class i am developing =
my level manager as a subclass of it redefining the ControlperFrame =
functions, hope its ok...=20

 And now im running with some troubles, the second one its my MAIN =
problem right now:

 - About importing meshes, what can i do to improve speed, on my =
project? On the old  DirectX project I used an indexed vertex buffer, =
can i use something alike under kgl? checking some Nehe tutorials i saw =
display lists are supported, are they ok? In the KOS GL headers i saw =
about opengl 1.2 arrays? What are they? Could some address me, please?

 - Finally, Ill explain my MAIN PROBLEM right now, i wont be able to go =
on with the project if i cant resolve it.... It's about a camera system:
 My old project used only ONE camera, based on UVN rotations which =
always followed the player, this meant that i never had to use =
Yaw/pitch/Roll angle rotations (sadly, i dont know if i can reach again =
the person who taugh me about it), but i realized that if i want to =
debug the 3D scene of my game i need to develop some cameras (mainly a =
FLYING-FPS and a TPH camera, and of course the game camera) and if its =
possible, I WOULD LIKE TO DEVELOP THEM  UNDER THE UVN system, so i think =
it will be faster than with the angle system (before asking why, chech =
this article http://www.gamedev.net/reference/articles/article1199.asp) =
.. I realized  that my knowledge about rotations, the matrix stack and =
the math behind OpenGL/DirectX is zero!! I tested the Tiki::Matrix =
rotation axis function but everything screwed up when i move the camera, =
even the debug text!!
=20
 Please, every detailed tutorial, code sample or explanation about the =
UVN math (matrix, vectors), the Opengl matrix stack, and matrix =
conversions to OpenGL or anything about the subject will be welcomed!!

Regards,

@B^)>

  I ran into the same problem with the debugger on win32 and tried your =
patch, it seems to work pretty well.  I'll test it a bit more and =
probably apply it later tonight.

  Thanks,

    Hi again,

    The console snake sample now works great!! Thanks!

    Anyway, i found a small problem that im trying to resolve, my laptop =
is a
    bit old and it only has 700Mb RAM, so when VC triggers a breakpoint =
my=20
    windows doesnt react well. I have a little experience programming in
    windows, but i have read that the Windows Message dispatching must =
be
    accurate so it doenst eat all the machine resources.... I have tried =
a small=20
    change on platgl.cpp on the DoMain function, and i think it works =
better
    now. Here are my changes, tell me what you think, i think it respect =
the
    multithreading in windows better.

    - Changed:

    /*while(m_hThread !=3D NULL && GetMessage(&msg, NULL, 0, 0))=20
    {
      TranslateMessage(&msg);
      DispatchMessage(&msg);
    }*/

    - To:

    while(m_hThread !=3D NULL)
    {
        do
        {
        if (GetMessage(&msg, NULL, NULL, NULL))
        {
       TranslateMessage(&msg);=20
       DispatchMessage(&msg);
        }

        } while (::PeekMessage(&msg, NULL, NULL, NULL, PM_REMOVE));

        Sleep(2);
    }

    I have tested it and it works fine on breakpoint and exceptions...
