{\listtext \'a5 }osgviewerCocoa (previously osgsimpleviewerCocoa in CVS) is an example program demonstrating tight integration between OpenSceneGraph and Cocoa. It demonstrates many of the things you should consider in building a first-class OS X application that uses OSG.\

\f0\b Notes for 2.0 release:\
\f1\b0 \cf0 1.2 was originally intended as a bug fix release for 1.1 (going for 1.1.1), but OSG broke ABI again so the number was bumped to 1.2. There are no significant changes to the Xcode projects or significant OS X specific changes.\
\f1\b0 OSG has changed its versioning number scheme. 2.0 is the stable release following 1.2.\
\
Producer has been removed from the distribution with osgViewer as its intended replacement.\
\
GDAL has also been removed from the distribution as it is no longer a dependency.\
\
OSG is in the process to moving to a new CMake based build system. Once the remaining Mac OS X support needed is implemented in CMake, the Xcode projects will be removed in favor of the new unified CMake system.\
\
With Leopard on the horizon, the need to deal with 64-bit readiness and deprecated APIs is becoming more critical. In a nutshell, we need a Cocoa based version of osgViewer, and the QuickTime plugin needs to be replaced. Currently, there is a new ImageIO based plugin to assume the image reading/writing duties of the old qt plugin. We are in need of a QTKit based plugin to assume the movie responsibilities of the old plugin. And we are in need of volunteers to write the Cocoa osgViewer backend. Currently, the example osgviewerCocoa demonstrates a lot of similar functionality and could be used as a reference. However, the example needs to be turned 'inside-out'. The example is an NSView class that contains OSG classes; the osgViewer needs to be the opposite where the OSG class needs to contain the NSView class.\

Since the 1.1 release, we have learned of serious problems (freezing of the window manager) on the (Intel) MacBook Pros using osgText. We believe the problem is with a serious driver bug for ATI in OS X 10.4.7. We believe the bug affects the ATI Radeon X1600. (You can get this string by calling glGetString(GL_RENDERER) when you have a valid OpenGL Context. The string returned to us on affected MacBook Pros is "ATI Radeon X1600 OpenGL Engine".)\

Apple lives and dies by the bug report system. If anything is to get done, it must be in the bug reporter. And they keep count of how many people file the same bug, so duplicates are good.\

These projects were primarily developed with gcc 4.0.1 under Tiger 10.4.3 using Xcode 2.2. Starting with gcc 4.0, Apple no longer statically links in the C++ runtime. Apple has made available the g++ 4.0 dynamic runtime for Panther under the 10.3.9 release. To run under Panther, your system must have this update (or you must recompile the binaries for your system).\

{\listtext \'a5 }I noticed that for some reason, Xcode has problems compiling the Carbon header with the OpenThreads framework when autovectorization and precompiled headers were enabled. You might try disabling precompiled headers if it is not already. If the problem persists, you may also need to delete the entry that enables autovectorization. In the Groups and Files panel (left side panel), open the Info inspector for the project (top item) and click on the Build tab. Scroll down to the bottom, and remove the autovectorization option. \
