Testers needed for jPCT->LWJGL

[EgonOlsen]

Ok, I will do this test only if I had a such OpenGLled test program. I don't have any games in this machine and does not know any freely avail games with OpenGL support.  If any1 could link here a native OpenGL test program, I could benchmark fps.

Try this one: http://www.jpct.net/download/projected.zip

Environment:
Win2k/256MB
Chip type: Matrox Millennium G400
DAC type: integrated 300Mhz
Memory size: 16MB
Adapter string: Matrox Millennium G400 AGP
Bios Information: v2.1.035
Driver version: 5.82.18.0

Lol, I got 1fps running this program. My comp can't do OpenGL. This is an integrated G400 with 16MB ram, so it's not a state of the art.

Your java program most likely works properly, it's just my machine cannot do anything with it.

It's capable of running Quake3 so it should be capable of running anything else. Back to the drawing board to select a valid display mode then

The "ProjectedTextures.exe" works fine in 16-bit and 32-bit mode, very slow in 24-bit. And I get the same problem as whome with TerrainGL (not running in 16-bit and 32-bit, running a slow as possible on 24-bit)

Intresting? Didn't think so ;-)

Ah, i guess it's a problem with 24bit then...good to know..

I run a java and native demo in the following computer, here is the results:

256MB, PentiumIII 860Mhz, NVidia Riva TNT2 Model 64, 16MB
Bios Information: 2.05.1903, Driver date: 30.9.1999

ProjectedTextures.exe
same results for 16bit and 32bit, no 24bit available.
-> 2 FPS
>>>>>>>>>>>>>>>>>>>>>>>>>>>
terraingl.jar (without software parameter)
color mode 16bit -> error: requires greater colour depth
color mode 32bit -> 7 FPS
>>>>>>>>>>>>>>>>>>>>>>>>>>>
terraingl.jar (with software parameter)
color mode 16bit -> 13 FPS, interestingly it works this time.
color mode 32bit -> 13 FPS

Here is .bat files I use to launch java demo.

[RunDemo.bat]
set cp=terraingl.jar
set lwjgl=..\lwjgl-0.4\lwjgl.jar
set lwjgl_dll=..\lwjgl-0.4
c:\j2sdk1.4.1_01\bin\java -Djava.library.path=%lwjgl_dll% -cp %cp%;%lwjgl% TerrainGL

[RunDemoWithSofware.bat]
set cp=terraingl.jar
set lwjgl=..\lwjgl-0.4\lwjgl.jar
set lwjgl_dll=..\lwjgl-0.4
c:\j2sdk1.4.1_01\bin\java -Djava.library.path=%lwjgl_dll% -cp %cp%;%lwjgl% TerrainGL software

Just post here an updated test programs if you want us to run it.

Ok, i made a new jar. Just replace the jar from the old opengltest.zip with this one.

http://www.jpct.net/download/terraingl.jar

The new version start in 640*480 windowed with 16bit for color, zbuffer and textures. To change that, four new parameters exist:

color32 - start in 32bit color mode
texture32 - use 32bit textures
zbuffer32 - use a 32bit depthbuffer
fullscreen - go fullscreen

Maybe this helps to find the problem. Your TNT2-M64 results are strange...that card isn't that great but not that(!) bad either...

[whome]

I've posted results to my webpage 'cause it's so long text. One thing to say, things are looking good now  

Tomorrow I can run it on Pentium III 800Mhz.

Please, verify my fullscreen problem described in a document. Anything to be done for it?

Thank you very much for your affords. I really appreciate it. The zbuffer32 switch is stupid as i'v e discovered on my own hardware (GF4)...24 would do, but 32 always fails...anyway, the fullscreen thing is something i'm aware of and i should have warned you (sorry). Actually, i was unsure to add it at all...problem is, that i'm closing the app by using a WindowEvent and there is no pure Java-window in fullscreen (at least you can't see it)...i haven't implemented a LWJGL conform way of capturing at least a key pressed (like ESC) to close the window...i was too lazy. The whole application is a quick and dirty conversion from a "software rendering only applet" i wrote some time ago. That's the reason why it lags such stuff. Sorry again and thank you for trying.

Ok, good to know I could help you somehow. Are you planning to publish a sourcecode somewhere later?

I know, that 3d stuff is out of my league atm but I could try learning it a bit by bit.

The "opengltest" is just a test of my engine's (jPCT) recently added OpenGL support. I won't release the sources of the engine until i've lost interest in it...which may never happen... What IS available are the sources for the famous test application (without the latest switches added) because that's an example i'm distributing with the engine's jar and doc. If you are interested in that part, it can be found here (in the examples-dir of the zip):

New Terraingl.jar version test:
256MB, PentiumIII 860Mhz, NVidia Riva TNT2 Model 64, 16MB
Bios Information: 2.05.1903, Driver date: 30.9.1999

only 16bit and 32bit colormodes available, run 5-10 FPS with all parameters. zbuffer32 did not work at all. I did not try a fullscreen due to exit problems in it.

Anyway, my homecomp (Cel500Mhz+G400) could run a new version very smooth with a proper parameters.

PIII+TNT2 could not run it smooth with any parameters available. :-(

Tried it on an Athlon XP 1600 running WindowsXP and using a Kyro-I based graphics card. It worked and looked fine. Around 90fps. Overclocking the card helped to increase performance, so my guess is thatit's fillrate limited on that card (what can you expect from a card clocked at 115 Mhz though?).

[gregorypierce]

Athlon 2000+
Ti4200
256MB Ram

~75 FPS.

I didn't have to do any find library path craziness to start mine either.

java -classpath terraingl.jar;lwjgl.jar;. TerrainGL color32 texture32

Worked just fine for me right out of the box.

[mhelles]

Matrox G400, 700 Mhz Athlon, 384 MB RAM.

Works like a charm. Just hit that "run_win_gl.bat" and off you go!

In OGL mode, it runs at about 48 fps (if I sit real still  ).

In software rendering mode, it runs at nearly 8 fps. Impressive.
