* src/osgPlugins/3ds/ReaderWriter3DS.cpp: From Farshid Lashkari,
|
||||
"The logic for handling opacity maps in the 3ds reader seems to
|
||||
be incorrect. It checks whether the diffuse texture contains
|
||||
transparency, instead of the opacity texture. If the diffuse does
|
||||
not contain an alpha channel it outputs the warning:
|
||||
|
||||
The plugin does not support images without alpha channel for
|
||||
opacity
|
||||
|
||||
This seems to indicate that the check for alpha should be against
|
||||
the opacity map. I've attached the updated file.

* src/osg/State.cpp: From Michael Bach Jensen and Robert Osfield,
|
||||
"As discussed
|
||||
(http://forum.openscenegraph.org/viewtopic.php?t=12027) here is
|
||||
my submission :-)
|
||||
|
||||
The following change to State.cpp fixes the case where textures
|
||||
in a stateset along with a compute shader program did not make
|
||||
those textures available to the shader, since it got evaluated
|
||||
before the texture bind(s)."
|
||||
|
||||
Note from Robert, Michael only change State::apply(StateSet*) so
|
||||
I also applied the same reversal in apply of texutre modes/state
|
||||
into the State::apply() method for consistency.

|
||||
* src/osgPlugins/ive/Text.cpp: Replaced the initialization of the
|
||||
strarray to use reseve instead of a initial size provided in the
|
||||
constructor as this was leading to a bug in output.

|
||||
|
||||
* src/osg/State.cpp: From Farshid Lashkari, "I just started looking
|
||||
into the shader composition feature. I enabled shader composition
|
||||
on the osg::State object and noticed a 6x increase in draw time.
|
||||
I figured that the default composer might have performance
|
||||
issues, so I created a custom ShaderComposer that overrides
|
||||
"getOrCreateProgram" and does nothing. This still resulted in a
|
||||
performance drop.
|
||||
|
||||
I looked into the "State::applyShaderComposition" method and
|
||||
noticed that it will print debug information to the osg::INFO
|
||||
stream. I commented that line out and the performance drop was
|
||||
gone.
|
||||
|
||||
I'm not sure if the printing was accidentally left in or is meant
|
||||
to be enabled. I've modified the function to only call the print
|
||||
function if INFO logging is enabled. I've attached the change."

* examples/osgphotoalbum/ImageReaderWriter.cpp, include/osg/Image,
|
||||
src/osg/Image.cpp, src/osgPlugins/dds/ReaderWriterDDS.cpp: From
|
||||
Marcin Prus and Robert Osfield, moved the key parts of the .dds
|
||||
plugins computeRowWidthInBytes implementation into the
|
||||
osg::Image::computeImageSizeInBytes(..) to
|
||||
address bugs in the computation of image size.

|

* src/osgPlugins/dds/ReaderWriterDDS.cpp: From Sukender, "Added
|
||||
".dds" file deletion on writing failure."

|
||||
|
||||
* src/osgPlugins/dds/ReaderWriterDDS.cpp: From Sukender, "Added
|
||||
vertical flipping to the writer depending on the
|
||||
Image::getOrigin() value (= flip the image when
|
||||
Image::BOTTOM_LEFT). Most of the time this will not change DDS
|
||||
writing (= no v-flip), as it seems images are rarely
|
||||
"BOTTOM_LEFT". To skip this behaviour, the "ddsNoAutoFlipWrite"
|
||||
option was added.
|
||||
I also moved a few lines of code about "dds_flip" option, and
|
||||
made options reading more like in other ReaderWriters."

|
||||
* src/osgPlugins/dds/ReaderWriterDDS.cpp: From Diane Delallée &
|
||||
Sukender, "Added some support of non-modulus-4 dimensions in
|
||||
S3TC-DXTC images (previous implementation seem just not to handle
|
||||
these properly).
|
||||
- Added missing packing value on S3TC images. Images are coded
|
||||
with 4x4 blocs, whatever the image size. So there is an
|
||||
horizontal packing of 4 pixels (2 bytes in DXT1, 4 bytes in
|
||||
DXT2-5).
|
||||
- Added crash guard against writing corrupted S3TC images.
|
||||
Notes:
|
||||
- What is missing is a support of "lines packing" in osg::Image
|
||||
(see code comments).
|
||||
- S3TC-DXTC vertical flipping crashes (access violation) with
|
||||
some unusual dimensions (see code). I could not implement missing
|
||||
cases, so I added guards to avoid crashing."

|

|
||||
* src/osg/Image.cpp, src/osg/dxtctool.cpp, src/osg/dxtctool.h: From
|
||||
Diane Delallée and Sukender, "1. Image.cpp
|
||||
Failure to perform a vertical flip on S3TC-DXTC now simply leaves
|
||||
the original image instead of corrupting it.
|
||||
Image.cpp was sometimes performing a "normal" (= for uncompressed
|
||||
images) vertical flip on S3TC-DXTC images, producing weird
|
||||
results.
|
||||
Actually, code was trying a "DXTC vertical flip" and relied on
|
||||
the result to call a "normal vertical flip". But when the "DXTC
|
||||
v-flip" encounters an error, this is is not necessarily because
|
||||
the image is not S3TC (ex: unhandled image dimensions)!
|
||||
So now the code simply does "if dxtc, then flip_dxtc; else
|
||||
flip_normal;".
|
||||
|
||||
Note from Robert Osfield, moved the isDXT function into the
|
||||
dxt_tool file and namespace.
