to make is easier to write code that can work on DrawElementUByte, UShort or UInt.
Changed the osgTerrain::GeometryTechnique so that it automatically chooses
the use of DrawElementUShort or DrawElementsUInt accordining to the size of the tile.

It expects 'src_pix_fmt' and 'dst_pix_fmt' to be of type 'PixelFormat' rather than int. The attached cast fixes this (for me).
I've also added Matroska video to the list of supported extensions"
Please look at the .diff files for details. I have already enjoyed the latest Chinese *big* movie "Red Cliff" with the fixed ffmpeg plugin and osgmovie. :D"

not applicable there."
Also, there was also a small bug in osgDB's CMakeLists.txt that was causing an error when I tested with CMake 2.4.4.

fragment shaders in .vert files :) )."
At the company where I work we model literally thousands of 3DS models for all types of objects. Most don't have transparent textures applied to them, but a few do. The issue is that a texture may have an alpha channel defined, yet its 3DS material definition is not marked as being an alpha source, or transparent. This can happen for any number of modelling reasons (so I'm told) but the net effect is that when a 3DS object is loaded with such a material applied, the stateset creation for the 3DS geometry omits to add the GL_BLEND attribute as neither of the conditions that it currently tests for are satisfied under this scenario.
However, one thing that is apparently an indication of transparency/alpha information that we do make use of when modelling, but that the 3DS reader omits to test, is that we assign to the transparent texture to the opacity_map of the 3DS material structure.
Now, having discussed with our modellers the theory behind the opacity map, it seems that it is safe to say that if an opacity map is specified, then the reader should really apply the GL_BLEND attribute as it is an indication of some form of blending being required between materials.
With this in mind, I have made a minor change to the function createStateSet below, from the ReaderWriter3DS.cpp file, that checks for an opacity map having been specified, and in such a scenario the GL_BLEND attribute is applied to the geometry. This fixed our issue, and thought it might be helpful to others."
osgText::Text and osgText::Text3D use the same font file.
The first really load the file and obtain an osgText::Font object,
the second use the cache created during the first load of the
font file, and so obtain an osgText::Font object instead of
osgText::Font3D object. To obtain an osgText::Font3D object,
osgText::Text3D call osgDB::readObjectFile(...) with an option
to specify the plugin we want an osgText::Font3D instead of
osgText::Font.
Generalised Problem:
In osgDB::Registry, loaded file cache is referenced by the name
of this file, so if I load a file with some options, and the cache
already contain object for this filename, I obtain an object
potentially not loaded with my options.
Behaviours:
Cache management is delegate to osgDB::Registry, but cache
coherence (load a file with option then reuse it, deactivate the
cache when load a specific file or don't cached the loaded file)
is user's responsibility.
Text3D solution:
Postfix the font file name by .text3d or something similar and then have the freetype plugin return
osgText::Font3D when it detects this.
This operation is done by osgText::readFont3DFile() which unsure the filename have .text3d as extension.
This is totaly transparent for user, and backward compatible.
BTW, I fix the bug about the Normal of 3D text. Currently, the front and wall face have
the same normal (0,0,1) in the Text3D object coordinate. Now the wall face have its own
normal array computed by the plugin.
BTW 2, I implement
- void Text3D::accept(osg::Drawable::ConstAttributeFunctor& af) const
- void Text3D::accept(osg::PrimitiveFunctor& pf) const
so now statistics are well reported.
