Re: [osg-users] osgTerrain::getTile returns nothing

Hi,

by the way:

&* annihilates itself - the adress of the content of an pointer is the pointer 
itself, so "Terrain" would be sufficient.

Re: [osg-users] osgTerrain::getTile returns nothing

2011-11-23 Thread Christiansen, Brad

Hi,

Terrain tiles register themselves with the terrain during one of the scene 
travesals. I cant remember off the top of my head if it occurs during the 
update or cull traversal, but I think it might be the update traversal. If the 
scene has not been traversed, the none of the tiles will have been regstered 
yet.

Have a look at the traverse method of TerrainTile, I think that is where the 
registration is done.

If you are using a VPB built terrain, all the tiles (except the tiles at level 
0 ) are pagged in via the database pager. If the terrain hasn't been rendered, 
then no tiles would have been loaded.

Cheers,
Brad

Subject: [osg-users] osgTerrain::getTile returns nothing

Hi,
I want to access TerrainTiles, but I get always a 0 Pointer.


Code:

ref_ptr model=osgDB::readNodeFile(Filename.toStdString());

//try to convert the node to an osg::Terrain and analyse it
ref_ptr Terrain(model->asTerrain());
if(Terrain)
{
  cout << "We have a terrain :)\n" << "...analyzing" << endl;
  osgTerrain::TerrainTile *Tile=Terrain->getTile(osgTerrain::TileID(0, 0, 0));
  cout << "Tile adress: " << Tile << endl;

  //get more detailed info:
  osgTerrain::TerrainTest* 
T=reinterpret_cast(&*Terrain);
  cout << "TestTerrain Size: " << T->_terrainTileMap.size() << endl;
}




The first thing that I checked is, whether my Node is an actual Terrain (which 
it is, as Terrain is not 0).
Then I'm trying to access a random tile, I supposed that 0,0,0 should always 
exist. But I get a 0-Pointer.
I can't access the TileMap from Terrain directly, so I copied the class 
declaration, made the members public and cast the pointer. (the debugger 
wouldn't show me any contents of _terrainTileMap.
But the map seams to be empty, size is 0. The documentation of Terrain is very 
short, so I don't see any way to access the tiles, or in other words, there 
seam to be no Tiles at all.

Thank you!

Cheers,
Jonathan

Hi,

Express does include the optimizer now and you can get it to build x64, but yo 
uhave to jump through a few hoops. From memory, you need to download the 
windows SDK, setup up some paths then create the x64 target manually within vs. 
Do a web search and you will find instructions.

  I think Express also lacks the optimizer.

Re: [osg-users] Problem loading IVE files

2011-11-23 Thread Christiansen, Brad

Hi,

If you have built everything from source, and havent installed any binary 
versions, you should have no issues.
The is an osgversion.exe application created as part of the standard build. 
This should dump the version of the core osg library to the console. My 3.0.0 
build reports 3.0.0 from this app and the plugins dir osgPlugins-3.0.0.

My latest trunk build reports 3.1.0 from osgversion.exe and the plugin folder 
is osgPlugins-3.1.0.

Cheers,
Brad

Hi and thank you again,

what you are saying is logical for me, but I am pretty sure that I didn't
rename that folder. In which step is defined that folder? As far as I
remember, I put the dependencies in the 3rdparty folder and run the cmake. I
have checked the cmake options, but I have not found where this plugin
folder is defined. How can I check that I am using the right dependencies?
The dependencies listed here are the right ones for osg 3.0.0 or for any
other version?:

http://www.openscenegraph.org/projects/osg/wiki/Downloads/Dependencies

Anyway, it is strange that the rest of the plugins are properly working. I
thought that IVE should be easier to be working than DAE, for example, which
is working for me.

Cheers!

Hi,

The plugin folders name does correlate to the version of the OSG that was
used to create the plugins. This is done to avoid loading plugins from a
different version of OSG.
This looks like your problem.

Hi,

thank you for your reply and sorry for the delay in my answer (I was on a
trip). Yes, I am using 3.0.0. What you can see in:

LoadLibraryA("(.)\osgPlugins-3.1.0\osgdb_ived.dll")

is not the OSG version. This is just the name of the plugins folder that,
for some reason, has been called 3.1.0, but I think that it is not related
with the actual version of OSG. If I am wrong, please let me know. :)

Anyway, I am still at the same point. I can load 3ds, dae or osg files, for
example, but still not possible to load IVE files.

Cheers!

Hi,

Just checking you don't have multiple version of OSG in your path. You said
bellow that you are using version 3.0.0 of OSG yet the output you posted
from dependency walker lists OSG version 3.1.0.

If you do have both version on your path, this could be your issue.

Re: [osg-users] [osgPPU] Blur artifacts in HDR effect

2011-11-23 Thread Jean-Sébastien Guay


Hello René,


maybe multisampling can reduce the problem.


The screenshot was with 4x MSAA active (in the camera->attach(...) call 
of the HDR code, where we bind a texture to the main scene camera which 
is then passed to the first unit in the osgPPU pipeline).


Perhaps you're suggesting I enable MSAA for one of the other stages in 
the pipeline? How would I do that?



also you can add an additional gausian blur to the image before
resampling to reduce the artifacts.


Again using the same separable blur (x and y passes)? So I would add two 
other units before the UnitInResampleOut?


Thanks for your suggestions,

J-S

Re: [osg-users] [osgPPU] Blur artifacts in HDR effect

2011-11-23 Thread René Molenaar

Hi,

maybe multisampling can reduce the problem.
using osgPPU hdr I noticed small details with high frequency (distant
lights) appearing and disappearing.

mutlisampling reduced these artifacts.
(It did however cause a one frame delay, which isn't very noticable until
you use a request redraw viewer,
or screencaptures)

also you can add an additional gausian blur to the image before resampling
to reduce the artifacts.

grtz,

René Molenaar
