"Geometry.cpp
Make sure number of normals match number of vertices when lit or
vertex-normal pairs are separated when geometries are merged by the
optimizer.
Ancillary.cpp
Improved support for multitexture effect field and use texture
environment from .attr file.
PaletteRecords.cpp
Use search path when looking for shader files.
PrimaryRecords.cpp
Added preset uniforms "TextureUnit0", "TextureUnit1", "TextureUnit2"
and "TextureUnit3" for GLSL shaders."
some of the files, the function readInt() would return
a 0 size. While linux will happily continue on,
creating 0 sized arrays, Windows immediately
blows up, with sparks sometimes flying out the
side of the machine!
I added a simple check for zero size in
each of the functions that allocates arrays
based on the size variable, and I thought
I'd pass it along. Now the program will
not die if it encounters an ive file with bad
data."
// GT: fix for symbol fonts (i.e. the Webdings font) as the wrong character are being
// returned, for symbol fonts in windows (FT_ENCONDING_MS_SYMBOL in freetype) the correct
// values are from 0xF000 to 0xF0FF not from 0x000 to 0x00FF (0 to 255) as you would expect.
// becuase Microsoft uses a private field for its symbol fonts ........

Added setting of osg_SimulationTime and osg_DeltaSimulationTime to the uniforms set by SceneView
Added frame(double simulationTime) and advance(double simulationTime) parameters to
osgViewer::SimpleViewer, Vewer and CompositeViewer.
Updated various examples and Nodes to use SimulationTime where appropriate.
text than an other well known txf loader. That means drawing them one on top
of the other I can only see differences due to different mipmapping ...
That is it introduces an additional gap of 0.1*height between the glyphs.
There is an additional mapping between upper and lowercase characters if one
of them is not available in the txf file.
And we have an artificial blank character that is very often missing in txf
files."
The cache works for nested externals but is cleared before the master
flight file is returned. I implemented texture caching using the same
mechanism."
Stephan and I tested it on Mac and Win.
Just a couple of notes:
* the plugin is able to load both regular 2D images and movie stream. There is a #define QT_HANDLE_IMAGES_ALSO mechanism to indicate whether to use it for images or not. This is defined by default on Mac only, to avoid conflicts with the standard windows plugins. See comments on QTUtils.h
* de-initialization of quicktime before exit is now left to an observer, which calls exitQuicktime() when last media loaded with the plugin is released. This prevent a crash on exit without need of any extra call external to the plugin."
The existing code uses a map with object ID's. The original code only applied the name to a node for a new ID only if the node did not already exist in the map. The problem was that there was another part of the code (when a parent was forward declared) that also created the node with the ID in the map, but it did not know its name. I simply made sure that the name was set regardless of whether or not the node was already in the map. "
--merged with fixes for texture coordinates(is this in CVS/SVN already)?
--changed above mentioned fix output level from osg::NOTIFY to osg::DEBUG_INFO
--added support for VRML97 ImageTextures.
--changed pointers to ref_pointers where possible.
--added format (method separated by "//////") for easier reading."
I have decided to just normalise the drive letter part of file names for the time being and also ensure that names of the format x:/xxxxx are treated as absolute paths. This will cover a lot of cases.
I have raised a bug against collada which hopefully should resolve some others. However there are some pathological cases which I have commented on in the code, these will probably never work properly unless there is a significant rewrite of the daeURI functionality. Hopefully they are rare."
dxfSection classes, so their members data are correctly deleted.
- changed some methods signatures to pass arguments by reference instead of
by value. The performance and memory usage are enhanced (the reader was
clogging the heap when reading some large DXF files)
The updated files have been compiled and tested with a variety of DXF files
on XP with VS2003, but the changes should not disturb any other compiler."
Performance tests on big models did not indicate any performance penalty in using doubles over floats,
so the move to doubles should mainly impact precision improvements for whole earth databases.
Also made improvements to osgUtil::PlaneIntersector and osgSim::ElevationSlice classes
Under this mode, each 4x4 texel block can selectively use an alpha component or none. When alpha-enabled blocks are present, this is not reported in the DDPF_ALPHAPIXELS bit in the pixel format flags causing the reader-writer to report the file as a 3-components file (GL_COMPRESSED_RGB_S3TC_DXT1_EXT). The fix requires looking at each 4x4 texel block to detect the presence of 1-bit alpha encoding. When such a block is found, the internal & pixel formats are reported as GL_COMPRESSED_RGBA_S3TC_DXT1_EXT instead.
See http://msdn.microsoft.com/library/default.asp?url=/library/en-us/directx9_c/Opaque_and_1_Bit_Alpha_Textures.asp for more information."
following improvements:
- When all unsupported entities (SOLIDS, TEXT, ...) have been filtered out
from a block, dxfInsert::drawScene() was crashing because it assumed that
the block was not empty. It now returns silently so the other blocks can
still be imported.
- The DXF reader assumed all vertices were read first, then the face
indices. But, from the DXF "documentation" (www.autodesk.com/dxf) :
"Polyface meshes created with the PFACE command are always generated with
all the vertex coordinate entities first, followed by the face definition
entities. The code within AutoCAD that processes polyface meshes requires
this ordering. Programs that generate polyface meshes in DXF should generate
all the vertices then all the faces. However, programs that read polyface
meshes from DXF should be tolerant of odd vertex and face ordering."
So now the importer ignores the posted number of vertices and face indices,
and uses the size of the lists instead."
