Re: [osg-users] Heap and Out Of Memory error on XP

Even if you did, the per process limit for 32 bit is 2G. 3. I think windows even restricts that a bit further. 4. MFC is a bloated beast that will take some of that 2G.

Has anybody used it in conjunction with OSG, particularly building the source with it. Does CMake throw a fit or is the transition straight forward? There have already been a few threads about this in the recent past. I use it at home (on Vista no less... I'm adventurous) and it works well. A few notes: 1. You need to upgrade to CMake 2.4.8 or 2.5.x (one of the nightly builds) for it to be able to generate projects for VS9. 2. Up until now, Mike's 3rd Party binaries for VS8 have worked for me. But I have not been using it that much so you may run into problems. Please report here if you do. All in all, I don't see much difference between 8 and 9, and they even seem to be binary-compatible except for the project/solution files (of course... they had to change something so old projects wouldn't work without a conversion...).

Re: [osg-users] Heap and Out Of Memory error on XP
To toss my 2cents in you could also investigate the /LARGEADDRESSAWARE switch. In addition, I'd recommend looking into a new heap manager. I've had success with SmartHeap by MicroQuill. Do you have to use MFC? MFC will fragment the heap a bit by loading DLLs all over the place. To illustrate the impact of this behavior build a simple consolse app, a basic MFC dialog app, and a no-frills Win32 SDK based app. In each app attempt allocate 2GB of RAM in various chunk sizes. The results may surprise you. My point is if you can get away from using MFC that might help. MFC is a good method to develop user interfaces on Win32 systems (or QT) but MFC does have its drawbacks. I'd strongly suggest you get an eval for SmartHeap (assuming you have budget) and see if that helps - it's trivial to plug in to existing code.

Re: [osg-users] best way for import 3d model with bump mapping
There's no simple answer to that one. The way you render bump mapping in Maya is probably a lot different than the ways you can render bump mapping with OSG and OpenGL. For a visual effect like bump mapping I usually try to export models from Maya so that they have all the textures necessary for the effect. Then I use osg::Program to apply a shader that achieves the effect using those textures. There are also other ways you can render bump mapping with less modern OpenGL techniques, but most people prefer to use shaders. - Terry Message: 20 Date: Wed, 30 Jan 2008 14:49:09 +0100 From: Simone Baldissini [EMAIL PROTECTED] Subject: [osg-users] best way for import 3d model with bump mapping To: osg-users@lists.openscenegraph.org Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=iso-8859-1 Hello, I need to import in osg a model made with Maya.

Re: [osg-users] osg clearnode
Hi Vincent,
I used to use a clearnode a while back..
All I do now with my mixed OpenGL and OSG is the following at setup..
All I do is the following..
sceneViewer-getCamera()-setClearMask(0);
You can put various GL_DEPTH_BUFFER_BIT, and colour buffer bits and so
on in the setClearMask to get your required level of clearing, or not..
Hope that helps,
Stephen.

I need to have my clearcolor and clear masks set outside of osg
glClear(...). If I set OSG;s viewport smaller than my main
viewport, I
can still see my scene is getting rendered behind OSG. Also, when I
use the
clearnode its setting OSG background to black(this is probably the
clue of
what I'm doing wrong). All I'm doing right now is rendering the
cownothing else. I am using the clearnode as shown below.
/This here is how I'm creating the viewer/
sceneViewer_[0] = new osgUtil::SceneView();
sceneViewer_[0]-setFrameStamp( frameStamp.get() );
sceneViewer_[0]-setDefaults( osgUtil::SceneView::STANDARD_SETTINGS
);
sceneViewer_[0]-setComputeNearFarMode(
osgUtil::CullVisitor::DO_NOT_COMPUTE_NEAR_FAR );
This here is how I'm adding the
clearnode /
osg::Node *loadedModel =
sgDB::readNodeFile(C:/Debug/cow.osg);
if (!loadedModel)
{
OutputDebugString(failed loading model);
system(pause);
}
osg::ClearNode *clear_node = new osg::ClearNode();
clear_node-setRequiresClear( false );
osg::StateSet *stateset = new osg::StateSet();
stateset-setMode( GL_RESCALE_NORMAL,
osg::StateAttribute::ON );
osg::PositionAttitudeTransform *transform0 = new
osg::PositionAttitudeTransform;
transform0-setStateSet(stateset);
transform0-addChild( loadedModel );
transform0-setPosition( osg::Vec3(0,0,0 ) );
clear_node-addChild( transform0 );
sceneViewer_[0]-setSceneData( clear_node );
