I agree with all of these.
However, If you want to use DirectX, why use SDL?
You know that your game is running only in Windows
So, why do you use SDL and not Windows API which is a a little bit faster?
I’m writing fully crossplatform game, but, if defined Win32 symbols, I’m
enabling Direct3D 9 support in my game - when game started first time, user
can select renderer that he like. Do you see, how it supported in Unreal
Tournament?
But if I can’t get SDL window’s Handle, than I need to create my own window,
i.e if I use OpenGL I need to create SDL window (because I want to write
crossplatform game) and parsing events by SDL. But if I use Direct3DRM I
need to create own window and parsing events by WinAPI. I should write big
same code two times :o(
Therefore I have one question to Sam Lantinga!!! If SDL creates window by
WinAPI (in win32 platform), SDL has handle of a window, simply it’s don’t
declared in header files, am I right? Therefore I can declare extern
variable with handle in my source code, is it so? If yes, how I can do it?
Finally, If you have start learning DirectX lately, I suggest you give it
up
and start learning OpenGL.
- It is cross-platform
- It is very easy to learn
- DirectX is changing in every version (Microsoft sucks) but OpenGL is the
same.
I write only with DX9 - I’m using vertex and pixel shaders, that
don’t supported by DX8. Game is too big and I can to distribute DirectX9
End-User version (34MB) with it.
- It is full hardware accellerated
- It is faster than DirectX (I believe)
Direct3D is faster than OpenGL in windows platform!
Different games show from 1.2 to 1.5 difference in FPS in favour of DX.
try read the red book. Is the OpenGL Bible
http://tassadar.physics.auth.gr/~chameleon/OpenGL/The%20Red%20Book/
I’m writing in OpenGL for two years and I was read Red Book from first to
last page for three times :o) It’s really great book!!!
But Direct3D has bigger speed in Windows and many effects, e.g. shadows,
collisions etc. Also Direct3D has better shaders support. So I should write
with support both API…

I really dont know what you are telling about. OpenGL is not a product
developed by MS. As I stated before they just bring a reference implementation
along. If you want the newest header files, download them from the OpenGL
website or from your hardware vendor homepage.
And what libs you are telling about? Because OpenGL is dynamically linked
you have to get the entry points into the shared lib (e.g. dll) by yourself or
use the default lib with standard bindings. Because at least OGL 1.1 is
present on nearly all plattforms you cannot link against a lib that needs entry
points from a shared lib of a later version. Your program would just crash. So
extensions were born. It is not a MS problem. Under linux you will have the
same problems. Thats the design of the OpenGL API.
Your answer just keeps the gap between MS and OpenSource advocates growing.

Dynamically linking means you have a DLL. You can use LoadLibrary() to load the DLL, and extract each function pointer using GetProcAddress(). Alternatively, you can use code written by someone else which does exactly that, and exposes just the resulting function pointers. This code is usually distributed in the form of a (static) library, which is what you link against.

About the portability issue, I was going to write a Direct3D/OpenGL
abstraction layer and program everything on top of that. Because SDL
doesn’t support Direct3D, I’ll also have to rewrite most of the stuff
SDL is already doing for me when using it on top of OpenGL. So I
believe SDL + Direct3D is actually a useful combination.
I agree. Right now my 2D sidescroller project has two modes: 2D SDL and
SDL/OpenGL. I’d love to add SDL/Direct3D to that list so that Windows users
with broken OpenGL can get the benefits of 3D acceleration.–
