RE: DX vs OpenGl

[Brad Broerman <bbroer@one.net>]

For beginners, I would suggest doing it the old fashoned way, using a DIB 
buffer to draw to instead of video ram, and move from there. It'll give 
everyone a taste for actually rendering the graphics, and basic Windows 
programming. The program could also be easily ported to Linux or DOS. as 
well.

  My 1st game engine was done in DOS originally, and I later ported it to 
Windows using the above method, and it worked great. Doing the reverse 
should not be too hard. Setting up a DIB and getting a pointer to the 
buffer is very easy, and using direct keyboard input is very easy too. I'm 
not sure of Joystick programming in Windows, but doing it in DOS is a 
breeze. I'm sure that there is a fairly easy way to get the stick values 
from Windows without resorting to Direct Input...

Hi,

soory, but do we really need to worry about all this, is it necasary for 
all this DX and GL stuff, cant we just use the stuff used in dos that made 
good games with good sound etc like theme hospital (dos version) and 
wolfenstien 3d and adfapt these for windows, also I am not to keen on using 
Visual C++.

Cya,
Rob.

  the trouble with open GL is that it is graphics only, no direct input or 
sound.  I tried OpenGL first when I ran into that problem.

  The reason I wanted open GL was because it worked so well on so many 
interfaces.

  However, I like games that have several layers of music and sound as well 
as gamepad/joy-stick support.  But that would be for future enhancement of 
a game project.

  as for docks both DirectX and OpenGL have SDK's.  DX SDK is perty good in 
my opinion while OpenGL leaves a lot to be desired.  OpenGL however has (in 
my opinion) better online tutorials.

  At this time I would suggest getting a good understanding of DirectX.

    Hi everybody !

    As i previous asked what yo chose between DirectX and OpenGl, i have 
now come up
    with a small understanding about them

    DX is locked to a software company, and can't be delevoped to another 
competer with
    another OS installed, type Linux or beos.
    OpenGL however is compatibel with linux aswell as windows.

    So the first round goes to OpenGL.

    Is there someone who can comment about they degree of programming skill 
needed to
    use the different system. How is the documentation to OpenGL and DX, 
witch is easiest
    to learn ????
