Changes in 1.2
- resolution switching didn't work with the newest Riva TNT drivers.....
implementing a more "brutal" resolution switching version .
- implementing resolution switching for OpenGL only version.
Changes in 1.1.
- compiled with DirectX6.1 (KNI-support)
- music should be more stereo now.
- Bug fixes
- sphere movement pre calculated. (for more correct benchmarks)
Tirtanium requires:
OpenGL/D3D Version
- DirectX 6 (Software/Hardware).
- OpenGL (opengl32.dll Software/Hardware) no miniGL Quake driver.
OpenGL only Version (for WinNT)
- OpenGL (opengl32.dll Software/Hardware) no miniGL Quake driver.
For correct Benchmarks:
64MB RAM for NORMAL texture version
256MB RAM for BIG texture version
Tirtanium features:
- Direct 3D and OpenGL in one program
- Single OpenGL version (for WinNT)
- DEMO, fully configurable: antialiasing, resolutions, colordeep, ....
- 3DEngine: dynamic fog simulation, multiple lightning, reflection mapping,......
- 3DInfo Buttom: memory info, refreshrate, Vsync detection
- DESKTOP 3D RENDERING :)
New BENCHMARKSYSTEM
- no limit in resolution or colordeep :)
- 2 BENCHMARK classes
- Single and MULTIPLE BENCHMARK (just one click to benchmark all avialble resolutions)
- Autodetection of OS, memory, refreshrate, Vsync ....
- Benchmarks will be written to bench.res file for easy handling .
- Separate multi document result Viewer for benchmark with filterfuctions
- music from BEAT
- using MIDAS Digital Audio System (Copyright 1996,1997 Housemarque Inc.)
Direct3D engine:
- uses untransformed and unlit Vertices.
means: fully use of 3DNOW
in DX6, KNI in DX7?
- uses the new DX6 automatic texture management
- use of the D3D lightning pipeline
OpenGL engine:
- fully use of the OpenGL lightning and transformation pipeline.
means: geometry processors are welcome :-)
- resolution switching in Direct Draw
Tirtanium is also a graphics demo for the for my university in Germany
FH Gummersbach and includes their spheres logo.
write me an e-mail.
BENCHMARKS:
You can't change the benchmark 3D settings,
Benchmark will use the startup settings and:
BENCHMARK NORMAL DETAIL:
VIEW DISTANCE: NORMAL FLY: NIGHT DYNAMICFOG: NORMAL DOUBLEBUFFERING MIPMAP OFF
BENCHMARK HIGH DETAIL:
VIEW DISTANCE: FAR FLY: NIGHT DYNAMICFOG: HIGH DOUBLEBUFFERING MIPMAP ON
BIG TEX will always use MIPMAP ON
I if send me benchmark results please fill out the benchmark dialog.
Send to email1: it120@gm.fh-koeln.de
Here is some Tirtanium help in FAQ form:
OpenGL vs Direct3D:
Q: The OpenGL version is slower than the D3D version, does this mean
OpenGL not as good as D3D?
A: I don't think so, because:
-most lowend 3D cards don't have an optimized driver
-some driver are optimized for glQuake, with cost to the rest of OpenGL functions
-OpenGL has a more advanced lightning pipeline
-OpenGL tries to emulate missing hardware functions, D3D just says: no go
-OpenGL is not so "lowlevel", in D3D the programmer must do much more "lowlevel" stuff
Startup errors:
Q: If I start TIRTANIUM I get an "linked to missing export DDRAW.DLL error".
A: You don't have DX6 installed, install DIRECTX 6 or higher.
Q: If I start TIRTANIUM I get an "missing opengl32.dll" error
A: Get an OpenGL hardware driver from your 3D card manufacture.
OR: Get the OpenGL software emulation from MS.
Copy the dll into the TIRTANIUM directory.
Q: TIRTANIUM crashes at the beginning.
A: TIRTANIUM uses a special feature DESKTOPRENDERING.
This doesn't work on every 3d card.
Disable DESKTOPRENDERING :
Edit the TIRTA.INI: disableDeskTopRendering=1
Q: TIRTANIUM say's "Desktop rendering failed"
A: OK DESKTOPRENDERING doesn't work in every resolution and colordeep:
TIRTANIUM must be started in a resolution with where the 3D card has hardwarendering.
->switch 16bit color deep DESKTOP.
DESKTOPRENDERING need a lot of video memory at startup, switch to lower res.
->Switch to a 640x480 DESKTOP.
DESKTOPRENDERING dosn't work on Voodoo, Voodoo2
->hey, thats hardware. I can't chance that :-(
Last solution: try softwareemulation:
Edit the TIRTA.INI: d3dDeskTopRenderingInSoftware=1
Q: Howto get a full OpenGL driver for VOODOO 1/2/RUSH/(BANSHEE?):
A: Two Soulutions:
The 3DFX full OpenGL driver.
http://www.3dfx.com/docs/opengl_beta/opengl_beta.html
(Beta 2.1 has no support for FOG )
Get the driver from 3DFX.
Install the driver.
Rename the 3dfxopengl.dll to opengl32.dll.
Copy the opengl32.dll into the demo directory.
The MESA VOODOO DRIVER
(has FOG but a little bit slower)
Go to Phil Frisbie's Programming Page.
http://www.geocities.com/SiliconValley/Lakes/7220/mesa.html
Get the precompiled dlls.
Copy the opengl32.dll into the demo directory.
Q: Better image quality on Mystique and Matrox Millenium II.
A: set TIRTA.INI d3dNoBlendHardware=1
Q: Some ALPHA Object looks very dark (TIRTANIUM LOGO).
A: some 3Dcard have some missinig blend modes (RIVA 128,.....)
set TIRTA.INI noBlendFuncSRCALPHA_DSTONE=1
Q: TIRTANIUM doens't work on my Matrox Millenium I.
A: HaHa, good joke.
Q: TIRTANIUM is very slow on my S3 Virge.
A: Try softwareemulation, maybe it's faster....
