Re: [osg-users] Parallel Split Shadow Map (Update)

2008-05-16 Thread Jean-Sébastien Guay 

Hello Adrian,

would it be possible to submit the latest code into the 
SVN repository.


I suggest you remove the --NVidia option as well in your submission, if 
it's not required anymore it can be misleading to users.

Hi Adrian,

I downloaded OSG 2.4.0 and replaced the 3 files:

osgshadow.cpp
ParallelSplitShadowMap
ParallelSplitShadowMap.cpp

by what you provided. In short, it doesn't work for me :-(

The ShadowTexture (--st) is the only shadow technique that 
works on my system (Linux openSuSE 10.3, ATI-X300 with 
proprietary fglrx driver), but this worked the same with 
2.3.4 (svn)

There seems to be a lot of arguments for --pssm, I tried 
some but they all produce the same : nothing to be seen, 
and "Warning: detected OpenGL error 'invalid operation' 
after RenderBin::draw(,)"

.../OpenSceneGraph/Data > osgshadow --pssm -2
PSSM PolygonOffset: units=0.5 factor=0.5

Are there some arguments I should try ?

Well, not exactly true: --ssm sort of does something, but 
not what it should. I can see the glider and the base, some 
shadows moving, but not where they should.

.../OpenSceneGraph/Data > osgshadow --ssm --base glider.osg
glLinkProgram "" FAILED
Program "" infolog:
Fragment shader(s) failed to link, no vertex shader(s) 
defined.
Fragment Shader not supported by HW
.../OpenSceneGraph/Data >

Hum, no shader in hardware ... let's see:

.../OpenSceneGraph/Data > glxinfo | grep -i shader
GL_ARB_fragment_program, GL_ARB_fragment_shader, 
GL_ARB_multisample,
GL_ARB_point_parameters, GL_ARB_point_sprite, 
GL_ARB_shader_objects,
GL_ARB_vertex_program, GL_ARB_vertex_shader, 
GL_ARB_window_pos,
GL_ATI_draw_buffers, GL_ATI_envmap_bumpmap, 
GL_ATI_fragment_shader,
.../OpenSceneGraph/Data >  

So there is some shader in the HW, but not recognised. Apart 
from the obvious (ATI drivers suck) I don't know what to 
think of this.

> PSSM PolygonOffset: units=0.5 factor=0.5

BTW, this proves that I tested the 2.4.0 OSG, because these 
values are different in 2.3.4

I see: in your demo.bat the line setting the file path is commented out:

REM set OSG_FILE_PATH=.;DATA

removing the REM shows the scenes 1 .. 3 correct on NVIDIA Geforce 5700 
Win XP SP2.


on ATI Radeon X1600 Dual monitor the 1st and 3rd scene shows only a 
small flickering outline where the shadow border should be. The chess 
scene is entirely black.


For your 4th scene there are no ive files cannes.ive and bati.ive in 
your rar file?

Hello Adrian,


Hi all windows USERS, did it work for you, and on which hardware
http://webaddon3d.assoftware.ch/AE/PSSM_SHADOW_TEST_OpenSceneGraph_WIN32.rar


Sorry, I was away for the weekend. I had to edit your demo.bat for two 
things:


a) like Ralph, I removed the REM from the line that sets OSG_FILE_PATH.
b) I added --screen 0 to all the osgshadow command lines.

With those two corrections, all four scenes render correctly, with shadows.

OS: Windows Vista 32 bit
HW: Intel QX6600, GeForce 8800GTX.

If I did not add --screen 0, the shadows flicker a lot. So that, in 
addition to having to run single threaded, will have to be fixed in the 
future...


Good work.

is there a way to investigate this "Warning: detected OpenGL

I've changed the osgshadow example to:

std::cout << "starting viewer loop..." << std::endl;
while (!viewer.done())
{
viewer.frame();
}

so the problem is in viewer.frame();
As before, --st (ShadowTexture) works well.

just checked again. I removed the other two REM's on PATH and

Works on WinXP SP2 GeForce FX5700, but slow frame rate (2.3 fps).

On WinXP SP2 ATI X1600 dual monitor the park scenes run fine using

the buildings like a self shadow offset which is to large. Chess scene

Hi all again,

now i came from ATI X1600M test, same artifact as you described, small
shadowed line. i will try to figure out where it comes from. i guess we have
to set another polygonoffset. 0.5,0.5 is may not as good as it seams to be.
may -0.5,-0.5 or -1.0,-1.0 will work for ATI and NVidia. please check this
with the option
for polygonoffset and tell me what is a good offset.

Hi Adrian,

I have run out of day, in my day long merge spree, so I'll need to
start up again tomorrow, at which point I'll check out your latest
changes.   If you have any further updates to the ones sent of the
23rd May please just send them through,

Cheers,
Robert.

Hi All,

I'm not sure if it's commercially fair to talk about but I need to know your
personal choices. Which graphics hardware is considered to be flawless and
most compatible with OSG? (to be used with Windows XP and Intel
architecture)

Thanks for the patience,

Depends on your own application, i am working with ATI and NVidia both are
rubost running with OSG. The question isn't really what kind of card is most
robust with OSG, better question is,
which vendor has best OpenGL driver, especially for Windows Based Systems.

but why are you asking this question under PSSM ?

Thanks Adrian, changes now merged and submitted.  Could you please
check what I have checked in matches your latest.

A couple of general comments - the chess.ive looks great with the new
updates PSSM, but for town models I have things only work OK when
looking near to straight down and close to the ground, looking along
the ground the results are extremely shaky and unusable.

Robert.

Re: [osg-users] Parallel Split Shadow Map (Update)

2008-05-28 Thread Robert Osfield 
Hi Adrian,

I forgot to mention, on review I spotted that you'd added a:

 osg::Light* _userLight;

Which raises a red flag, as a possible cause for a dangling pointer to
be introduced.  A better pointer type would probably be a ref_ptr<> or
observer_ptr<>.   I have followed up on all the different code paths
that set/use this pointer so it may be perfect safe, but I thought I'd
raise a flag now and let you review the code in the context of what
happens when external objects get deleted.

Robert.

Re: [osg-users] Parallel Split Shadow Map (Update)

2008-05-28 Thread Adrian Egli OpenSceneGraph (3D) 
Hi Robert,

can you might post a screenshot of your terrain running with PSSM?
one trick would be to limit the frustum with the option --maxFarDist 250 for
250meter.
this will help to win performance, because we just render a smaller scene,
and the shadow quality become better. i guess we don't need to shadow a
whole terrain, only a sub-scene close enough to the camera.
