[Dev-C++] moving to 3d programming

[dein_metzger <dei...@ya...>]

 Hi to the list.
 I use directdraw for 2d graphics programming.
 I am thinking about learning 3d graphics programming.
 What=B4s the better? opengl or direct3d?

 thanks in advance,

 InacioW-

OpenGL. (cross-platform, tradition, easy to understand, lots of 
tutorials, part of mingw - no need to download anything else, etc.)

Hi!

I have Unreal Tournament, and I have recently made some screenshots with 
both the Direct3D renderer, and both the OpenGL renderer. I made them 
only for comparison for myself, later I realised, that they also might 
come in handy for this thread. UT version is 4.36, and I downloaded the 
new OpenGL driver for UT from
http://cwdohnal.home.mindspring.com/utglr/

So, here are the results:
http://bigbrother.vac.hu/~einstein/unreal/

The filenames are obvius. I saved them in nearly best quality JPG (90 
setting in IrfanView). The text on the shots is Hungarian though, but 
you should also notice the framerates. "Átlag" on the right means 
"Average" and "Utolsó másodperc" means "Last second".
Also, I tried to set up both drivers for maximum quality through the 
UnrealTournament.ini file. Here are the settings for the OpenGL driver:

[OpenGLDrv.OpenGLRenderDevice]
Translucency=True
VolumetricLighting=True
ShinySurfaces=True
Coronas=True
HighDetailActors=True
DetailTextures=True
FastTranslucency=False
VertexLighting=True
UseTNT=False
UseTrilinear=True
UseS3TC=False
UseAA=False
UseVertexProgram=False
UseCVA=False
ColorizeDetailTextures=False
DetailClipping=False
UseVertexSpecular=True
LODBias=0.000000
MaxAnisotropy=0
SupportsLazyTextures=True
GammaOffset=0.420000
NumAASamples=0
SwapInterval=0
UseMultiDrawArrays=True
UseSSE=2
AAFilterHint=0
TexDXT1ToDXT3=True
DynamicTexIdRecycleLevel=100
UseTexPool=True
UseTexIdPool=True
BufferClippedActorTris=True
SinglePassDetail=True
UseDetailAlpha=True
NoFiltering=False
UseFilterSGIS=False
Use4444Textures=False
UseAlphaPalette=True
UsePrecache=False
AlwaysMipmap=True
ShareLists=True
UseMultiTexture=True
MaskedTextureHack=False
MaxTMUnits=0


And for the D3D driver:

[D3DDrv.D3DRenderDevice]
Translucency=True
VolumetricLighting=True
ShinySurfaces=True
Coronas=True
HighDetailActors=True
UseMipmapping=True
UseTrilinear=True
UseMultitexture=True
UsePageFlipping=True
UsePalettes=True
UseFullscreen=True
UseGammaCorrection=True
DetailTextures=True
Use3dfx=False
UseTripleBuffering=True
UsePrecache=False
Use32BitTextures=True
DescFlags=1
dwDeviceId=272
dwVendorId=4318
UseVSync=False
Description=NVIDIA GeForce2 MX/MX 400 (Omega 9M 1.4345)
Use32BitZBuffer=True
UseVertexFog=True
UseAGPTextures=False
UseVideoMemoryVB=False


I hope at least this stuff will be entertaining. Bye.

All right, I have extended them with the software renderer verisons of 
the same shots (*_SWR.jpg).
Here are it's settings (a bit tweaked by me):

[SoftDrv.SoftwareRenderDevice]
Translucency=True
VolumetricLighting=True
ShinySurfaces=True
Coronas=True
HighDetailActors=True
HighResTextureSmooth=True
LowResTextureSmooth=True
FastTranslucency=False
DetailTextures=True


So, as an alternative, you can still write a software renderer instead 
of using D3D or OGL at all. Good luck :)
(BTW, who sais that UT doesn't have a decent software renderer? - It 
makes 20 FPS at least...)
(Celeron 433 running at 540 MHz, 256 MB RAM, GeForce2 MX400 32MB)

Have fun!
