help manage the scaling of particles, whether they should be relative to the
local coordiante frame of the particle system, or be in world coordinates.
1) Full DOS paths are now correctly opened by OpenVRML. A URL containing
a DOS path should be "file:///C:data/blah" rather than "file://C:data/blah".
2) The last primitive defined in "coordIndex" is now added if the
"coordIndex" is not terminated by -1.
3) Smoothed normals are computed if no normal field is provided.
Currently, there is no support for "creaseAngle", so all edges (even the
ones sharper than the creaseAngle) are smoothed. I might add this in the
future if demand rises.
4) If an IndexedFaceSet contains only triangles or quads then the
primitive type is set to TRIANGLES or QUADS, and the primset becomes
DrawArrays rather than DrawArrayLengths.
Question: I noticed that for DrawArrays you can still provide an index
array. Would the rendering be faster if I'd create DrawElements primsets
rather than DrawArrays? Phrased differently, what is the benefit of
using DrawElements over DrawArrays, as there is clearly not a one-to-one
mapping of these concepts to their OpenGL counterparts?
5) Objects are added to the transparent bin and blend mode is enabled
only if the transparency is nonzero. Rendered transparent objects no
longer write the depth buffer."
"texture" paths. This is to drop absolute paths that some
3d editors export (even AC3D itself!). But this also strips
directories of relative paths, which is wrong and contradicts
the ac3d reference implementation. (The reference implementation
doesn't strip anything, though, and so takes the absolute paths
as they are. Definitely not what we want.)
The attached solution checks absolute paths and only strips
those:
(1) A:\\foo\\bar.png -> bar.png (as before)
(2) /foo/bar.png -> bar.png (as before)
(3) foo/bar.png -> foo/bar.png (new)
(4) ../foo/bar.png -> ../foo/bar.png (new)

The files are:
include/osgSim/ObjectRecordData -- The new class. Derives from Object to support .osg IO.
src/osgPlugins/OpenFlight/PrimaryRecords.cpp -- Reads data into that class.
src/osgPlugins/osgSim/IO_ObjectRecordData.cpp -- .osg IO support."
From Robert Osfield, made the OpenFlight read object record data optional via the -O readObjectRecordData ReaderWriter option.
this fix strips whitespace off externally referenced material files.
fixes a bug where the obj listed something like:
mtllib FR_PARIS_ESPACE_UNESCO_S.MTL
and then that caused failures in the load later:
FindFileInPath() : trying /Users/rpk/Downloads/
FR_PARIS_ESPACE_UNESCO_S.MTL ...
this fix simply strips whitespace around that filename before passing
it on to the remainder of the loader."
Changes from Robert Osfield, change std::cout to osg::notify(osg::INFO)
It contained a bug that would cause freed memory to be written again.
Specifically, in FreeTypeLibrary::~FreeTypeLibrary(), calling
font->setImplementation(0); deletes the content pointed to by the
fontImplementation pointer, while the line the immediately follows
tries to access it.
My fix is to make the second instruction part of an else clause rather
than always executed. This way, the fontImplementation->_facade = 0
instruction is only executed when the font implementation is not set
to 0 before (although I have no idea what it is here for and if this
code path is ever followed, since I don't know the plugin's internals
very well).
Attached is the modified FreeTypeLibrary.cpp file."
last primary node inside a push-pop level would not get the dispose()
call. This would result in information from some ancillary records,
like the matrix (transform), being lost.
Changes are made to the latest version in the repository.
Thanks to Terry for the help to find and fix the bug and test the changes."
.shp ...) ogr is a part of gdal so i added the build of ogr plugin if
gdal is found.
to test it
osgviewerd -e ogr file.tab
or
osgviewerd -e ogr file.gml
or
osgviewerd -e ogr file.shp
"
from Quicktime/Quicktime.h to QuickTime/QuickTime.h.
MacOsX filesystem is normally case insensitive, but in
my case I changed that option and the quicktime headers
were not found. Now compiles fine and on case insesitive
file systems should work correctly too. "
