Hi Chuck & all,
Did this ever get addressed? I have an OSG 2.8.3 app which i am trying to
port to 64-bit Mac (i.e. Cocoa). As of 2.8.4, i see that QOSGWidget.cpp
still has this limitation:
#elif defined(__APPLE__) // Assume using Carbon on Mac.
Is it worth continuing to try to build 2.8.3's Q
Thanks Robert, for include/osg/Config. Starting with OSG 2.6, the VTP can now
check OSG_USE_FLOAT_MATRIX to detect whether OSG was built with float matrices
or not. That makes it easy to handle both cases, so the user doesn't need it
built one way or the other.
It is not so surprising that th
m just not finding it, is it in OSG somewhere? I did search the
list archive, and found no relevant mention of 'convergence'.
Thanks,
Ben

Hi Ben
> As far
Rick,
Is the problem specific to your exact platform? glutSimple runs fine
elsewhere, including the Windows and Ubuntu boxes here.
The most likely explanation is that you have two copies of OSG on your system,
compiling against the headers of one, linking against the other.

I found what appears to be another bug/limitation in ShadowMap.cpp. When
traversing the nodes which cast shadows, it uses this code:
cv.setTraversalMask( traversalMask &
getShadowedScene()->getCastsShadowTraversalMask() );
'traversalMask' here is the sceneview's draw mask, which defaults to

Alejandro,
I suspect the most likely explanation is this:
1. You are using ShadowTexture, which AFAIK doesn't support self-shadowing.
2. ShadowTexture is ignoring your ReceivesShadow bit, however:
3. When you turn on CastsShadow for a node, it is then implicitly preventing it
from receiving a sh

There's something i'm not understanding about osgShadow, and it's probably a
basic behavior of OSG.
So, the simple question first:
The default node mask for all nodes is 0x.
It i set the mask to 0, then the node (and its children) is not drawn.
If i set the mask to some other value, then

What is this HUD? It sounds very interes
Thanks to J-S and the others who have filled in the osgshadow documentation, it
is really starting to come together.
Question of the day: I find a setTextureSize method on ShadowMap and
SoftShadowMap, but not on the 3 other techniques (even in SVN head). In
particular ShadowTexture has code li
I have updated the page with a link to GPU Gems 2, i guessed at which article
is meant. Any more details you can divulge about SSM? SSM definitely does not
work on my (fairly old) ATI Radeon 9800, perhaps this is due to needing some
specific modern shader capability?
Thanks,

Alright. I have created a wiki page here, with my best attempt at documenting
what i've learned so far:

things like:

Reed,
OSG on Windows passes your strings directly to fopen, or the C++ stream
equivalent. File paths are assumed to be in the local OS's filesystem
character set. This means that e.g. Chinese filenames can be opened on
computers with Chinese version of Windows, and Western filenames can be op

OK - where are the doxygen docs for OpenThreads?

Next question: does OpenThreads have any documentation, at all? I have looked

Aha. I guess what happened is this:
Figuring that 2.0 has been out long enough now that it must be time to upgrade
from 1.2, i tried to build OSG 2.0 this evening.
