Hi Robert,
Thank you for the suggestion. I have attached the notify log. In
summary, the log includes a number of entries for features not supported
by the OpenGL driver, including GL_ARB_vertex_buffer_object. There are a
number of glBufferData errors in the log, but I am not sure of their
severity.
I did not see the OpenGL version reported in the log, but OpenGL
Extension viewer reports 1.1 and also agrees with the extension support
reported in the log.
I will continue to experiment.
Thanks,
Judson

Hi Judson,
I haven't played with using virtual machines for rendering so don't
have first hand experience. For item 1 - version detection and
extension usage, this should in theory work, with the OSG
automatically detecting OpenGL 1.1 and lack of VBO support and not
using it. The error you are seeing is either the driver claiming to
support VBO's or the OSG missing this check. Check what OpenGL
version is passed back.
Running the OSG with OSG_NOTIFY_LEVEL set to DEBUG or programatically
with osg::setNotifyLevel(osg::DEBUG_INFO); will report what version
and extensions are supported to the console, along with lots of other
stuff too, but redirect the output to a file and then browse through.
This should tell you what the OSG has got back from the driver.
Robert.

Hello,
I have been testing in VirtualBox recently, and encountered two problems
that I was hoping someone might recognize. Note: The problems do not occur
outside of a virtual environment.
1. I have geometry in my model where I call
osg::Geometry::setUseVertexBufferObjects(true), but the virtual environment
only supports OpenGL 1.1. An access violation occurs shortly after calling
glDrawElements() from DrawElementsUInt::draw().
The last portion of the call stack is as follows (access violation in
memcpy() trying to access 0x4fbc):
msvcrt.dll!memcpy() + 0x31 bytes
opengl32.dll!__gllc_ReducedElementsHandler() + 0x285 bytes
opengl32.dll!ReduceDrawElements() + 0x1cb bytes
opengl32.dll!__gllc_DrawElements() + 0x121 bytes
osg92-osg.dll!osg::DrawElementsUInt::draw(osg::State & state={...}, bool
useVertexBufferObjects=false)
osg92-osg.dll!osg::Geometry::drawImplementation(osg::RenderInfo &
renderInfo={...})
Taking out the call to setUseVertexBufferObjects() seems to fix the problem.
Do I have to detect the OpenGL version explicitly, or is the OSG library
supposed to fallback to a non-VBO mode of operation automatically?
Also, prior to the crash, I get various "Error: glBufferData not supported
by OpenGL driver" notifications. Also a glGenBuffers() and glBindBuffer()
error notification, and a Windows error #127 that mentions
wglChoosePixelFormatARB ext not found.
2. If I enable 3D acceleration in VirtualBox, there is no crash, but the
scene ends up opening as a separate window and takes up the entire screen. I
am not sure how much this issue relates to OSG though.
Spy++ shows a window class of "OSG Graphics Window for Win32 [{with
cursor}]", that is not visible in Spy if the window opens as a child window
with a non-null parent as expected.
Has anyone had success viewing their models using VirtualBox? or VMWare?
Thanks,
Judson
