hi,

i’ve coded a java webstart picking demo.
it could be a small test for 3D GUI.

it is embedded into “joglRunner”

joglRunner, the main program, can be used to start the demos.
start the last one first, cause’ GC problems (eventually).

known problems are old graphic cards and MESA
???

which config do you use ?
does this picking demo work ?
fps ?

thank you for feedback,
wish you best code,
olaf

anyone here who can tell me that this test is running on a mac computer ?

thank you,

Hi Olaf,

the demo went just great. The picking demo looks quite impressive to me. I’m interested how the technology would look in filebee.
The pickingdemo ran wich 47fps. I think thats the only demo your focused on right now, right?

Specs:
Windows XP Pro
Athlon 1800+
ATI Radeon 9500
1024MB RAM
Java 1.4.2_04

thanks for looking+testing !

update with moving camera available now…

Hi olaf7,
All works fine on my Apple here except for the known generic fullscreen bug - I just get a blank white screen in fullscreen mode.

I get roughly 21fps with my iBook G4 800, so, quite slow (I’ve been able to keep my 2D OpenGL applications to 100fps with high resolution timers and such.

Other system details:
640MB RAM,
OS X (10.3.3),
1024 x 768 resolution

Let me know if you want me to do any more testing!

Regards,

ribot.

Gday Olaf.

Here’s some details for you.

I ran the test, generally fine, albeit with a few incorrectly highlighted buttons etc. Fullscreen was pretty dodgy too.

3.2GHz P4
1024MB RAM
Mobile Radeon 9700 - 1900x1200@60Hz
JDK 1.5beta
Windows XP

In a window:
53fps
23% cpu load

In fullscreen:
20fps
40% cpu load

Hey,

Cool demo.

FYI:
P4 1.9 GHz
Radeon 9600 XT

Windowed:
~30 fps when moving mouse
~60 fps when doing nothing

Seems like you should be able to get a much better frame rate. Are you using display lists, vertex arrays, or any of the other batching methods? You could potentially get away with only three objects; the globe, the button panel, and the active button (drawn over the rest of the panel). You may also benefit from the 1.5 timer. A choppy frame rate will blow any demo.

Anyways, I though the demo was pretty cool. Keep up the good work.

Just ran on my G5 and it works great.

System:
Dual processor G5 @ 1.8 GHz
GPU: GFX 5200 Ultra
~52 fps

I suspect the consistent frame rate on the G5 is due to the better multithreading and dual processors.

jogl tests have an option dialog now.
(sleep + sound)

faster here:-)
http://filebee.org/test/jogl2/joglTests2.jnlp

linux mandrake 9.2
1 GHz athlon, 1 GB ram
geforce 2mx card

in window (800x600):
-sleep(10) => 33 FPS
-no sleep => 54 FPS

in window (1152x864 - pseudo fullscreen)
-sleep(10) => 32 FPS
-no sleep => 36 FPS

note about tuning:
gui elements cannot be optimized very good in my enviroment.
i think it is in the nature of gui, that some elements have a short life.
in a couple of weeks you will see more than simple 3D buttons.
if performance will become very slow, i’ll see how to tune.
for now i concentrate my work on implementing the gui3d.* package.

thank you for your comments + tips
and apologize my rusty school english.

greetZ2all and wish you best code!
