New features
+Read and write of osg::LOD, osg::Switch, osgSim::Sequence, osgim::MultiSwitch and osgSim::DOFTransform data in <extra>
+Read and write of osg::Node description data in <extra>
+Plugin option "NoExtras" to prevent writing of <extra> data and only traverse the active children when saving
Changes/additions
+instanced_geometry and instanced_controller are now loaded in a single Geode with multiple Geometries instead of multiple geodes with a single Geometry
+Changed all calls to the deprecated createAndPlace() to the new add() methods
+All transformation elements <scale>, <rotate>, <translate>, <lookat>, <matrix>, <skew> are now concatenated properly in to a single MatrixTransform.
Previously this was not done in order as required by Collada and and not all elements were included.
+Complete skew matrix creation
+Automatically add GL_RESCALE_NORMAL if scale is non-identity
+Blinn shininess remapping to [0,128] when in range [0,1]
+Changes to CMake file to make it compile on Windows
+Coding style and code documentation
Bug fixes
+Transparent texture writing fixed
+Fixed bug in using osg node name as collada node ID
+Fixed usage of double sided faces in GOOGLEEARTH extra
+Not adding blendfunc and blendcolor when opaque
TODO/Wishlist
-solve differences in drawables, DAE reader should place multiple collation elements into multiple primitivesets in a single geometry where possible (only when same material)
-solve differences in matrices
-multitexture support
-skinned mesh and generic animations using osgAnimation
-profile_GLSL based on COLLADA OpenGL Effects Viewer http://ati.amd.com/developer/rendermonkey/downloads.html
-handling more <extra> to more closely mimic the intended lighting"
support. While testing the pluggin we found a small bug and we are
submitting a patch.
The first attachment is a small program that creates a scene with two
pyramids, transformed by two instances of
osg::PositionAttitudeTransform. One of them is rotated 90 degrees in
the X axis, and the scene is exported both in the native OSG (.osg)
and COLLADA (.dae) formats. In the first case the rotated pyramid is
displayed correctly whereas in the second the pyramid seems not to be
rotated.
In the COLLADA 1.4.1 specification (found at
http://www.khronos.org/collada/) it is specified that
"The <rotate> element contains a list of four floating-point values
[...] followed by an angle in degrees" but the plugin seems to write
the value in radians.
The problem seems to be in the method daeWriter::apply() that seems to
be writing the angle value in radians to the COLLADA file. The patch
can be found in the second attachment and is simply a call to
RadiansToDegrees wrapped around the angle.
