* Support for Box, Sphere, Cone, and Cylinder. These nodes are converted
to osg::Geometry conform the VRML97 spec.
* Backface culling is enabled/disabled according to the "solid" flag for
geometries that are converted from IndexFaceSets.
* PROTO instances can now be used for "appearance" and "geometry" fields
in a Shape node.
The file ReaderWriterVRML2.cpp is adapted for the latest stable public
release:
http://www.openscenegraph.org/svn/osg/OpenSceneGraph/tags/OpenSceneGraph-2.2.0
The changes where needed for being able to read VRML file which are
output by VMD (http://www.ks.uiuc.edu/Research/vmd/). A sample VRML file
is enclosed in this submission.
The plugin has been tested against a number of VRML samples that include
texturing. The texturing is found to be VRML97 compliant for all added
geometry nodes.

with the shader for textured objects. This works very well in cases
where there could be a mix of textured and non-textured objects in the
scene, and it makes the initialization more robust.
The idea is from PSSM, to add a 1pixel texture to the main rendering as
to provide white for any objects missing textures."
You were right about the CMAKE_MODULE_LINKER_FLAGS option for CMake, so here is a modification allowing to not generate the manifest files for the plugins making them a lot more easy to redistribute. I have also made the same modification to the wrappers as they are also put into the osgPlugin folder when generated.
"
case is the more tested case, and therefore it is correct to set
_supportsVertexBufferObjects to the same value as _fastPath. So here's a
change that does the same thing for the env var case."
both Jeremy and Anders added static build support as an option, but one was
for Unix and one for Windowsm, but the two mods were also inconsitent in naming
and implementation. I have had a bash at merging them both, but don't know yet
if these changes will work yet on either configuration... user testing will tell...
enhanced version of PolytopeIntersector.
New features of PolytopeIntersector :
* Dimension mask: The user may specify the dimensions of the
primitives to be tested. Checking polytope-triangle and
polytope-quad intersections is rather slow so this can
be turned off.
* Reference plane: The resulting intersections are sorted
by the distance to this plane.
New memebers of PolytopeIntersector::Intersection :
* distance: Distance of localIntersectionPoint to the reference plane
* maxDistance: Maximum distance of all intersectionPoints to the
reference plane.
* intersectionPoints: The points intersecting the planes of the polytope
or points completely inside the polytope.
* localIntersectionPoint: arithmetic mean of all intersection points
* primitiveIndex: Index of the primitive that intersected
I added some more output to the example osgkeyboardmouse."
with the original AdapterWidget implementation still available by default. The new implementation can be accessed by running:
osgviewerQT cow.osg --QOSGWidget
all wonky when I resize the SDL window. I'm not sure if this bug has
always existed or not, but according to the SDL documentation this
operation should be safe regardless, and doesn't not introduce the need
for extra memory management (that is: there is no need to "cleanup" the
old screen variable, that is all handled by SDL for us).
"
highlighted problems with Light, ClipPlane and Hint usage in osg::State's usage of cloneType
and reassignment of target/num in StateSet/these StateAttributes.
size of the image data is greater than the actual image size. This
causes the memcpy call to go out of the array bounds. I modified the
code so that it copies the data during the iteration, instead of
memcpy'ing. This fixes the problems i was having.
If you are curious, the writer was crashing when trying to write an
RGB image that was 2050 x 1280. You might be able to reproduce it by
allocating an empty image of that size and writing it to a file."
window. This breaks rendering in for example MFC SDI applications and in
MFC MDI applications if user resizes the window so that client area has
zero height. Current safeguard for minimized window:
LRESULT GraphicsWindowWin32::handleNativeWindowingEvent( HWND hwnd, UINT
uMsg, WPARAM wParam, LPARAM lParam )
...
/////////////////
case WM_MOVE :
case WM_SIZE :
/////////////////
...
if (clientRect.bottom==0 && clientRect.right==0)
...
does not cover this situation. In these situations clientRect.bottom = 0
and clientRect.right > 0.
Quick fix to this is relax condition:
if (clientRect.bottom==0 || clientRect.right==0)
Modified file is attached.
Tested with osgviewerMFC from 2.2.0 release (Windows XP sp2)
Before fix:
- execute from command line osgviewerMFC.exe cow.osg.
- the cow is rendered nicely.
- resize window to zero height by dragging from bottom border upwards.
- resize window back to original height
- just blue screen, no cow
After fix:
- execute from command line osgviewerMFC.exe cow.osg.
- the cow is rendered nicely.
- resize window to zero height by dragging from bottom border upwards.
- resize window back to original height
- the cow is where it is supposed to be.

- Get or set the target number of PagedLOD children to remove per frame.
- Get or set the minimum number of inactive PagedLOD to keep.
Corresponding environment variables have been added too.
The default values reproduce the previous DatabasePager behavior."
