osg::DisplaySettings class. OsgCameraGroup will now read the setting
from the DisplaySettings instead of hardcoding the value. I added the
following commandline option to be able to set the multisample value:
--samples <num>
One thing to note, OsgCameraGroup would previously check if the
computer is an SGI and set multisample to 4. I retained this check in
DisplaySettings to be backwards compatible."
keyboard and mouse events.
Added osgGA::EventQueue class to support a thread safe event queue and adaption
of keyboard and mouse events.
Removed osgProducer::EventAdapter as GUIEventAdapter replaces it.
Adapted osgProducer and examples to work with the new changes to osgGA.
an invalid bounding sphere if it hasn't seen a cull traversal yet. It
depends on _firstTimeToSetEyePoint, which is initially true, then false
after a cull. There might be a better way? If so, let me know.
This change does resolve the issue I had encountered with auto scale to
screen and incorrect culling."
Added better handling in computeIntersections(..) of nodes that are internal
to the scene graph, correctly accounting for the accumulated transforms.
Changed the EventVisitor so that it only traveses active children rather than
all children.
Updated wrappers.
Normally the automatic setup is useful, but in the case of the .osg support this automatic
update was forcing premature loading of imagery that wasn't necessarily, and can lead to
reports of looking for files that arn't present.
change of ' ' to GUIEventAdapter::KEY_Space, fix to url in Matrix_implementation.cpp.
Syntax fixes by Robert Osfield to above submission fix inconsistencies with normal
OSG coding style.
methods, two that takes an index,two that takes a key value. Updated the ViewEventHandler
so the it now uses the getMatrixManipulatorWithIndex() method to avoid previous ambiguity.
I spent some more time debugging and it turns out there was a bug in
the ParticleSystem::update_bounds function. When the bound is being
reset, both the min and max are being set to the same postion without
the radius being subtracted/added to it. When there is only one
particle alive in the system this causes it to be culled by small
feature culling. I've modifed the function so that when the bound is
reset, the radius is subtracted/added to the position. This fixes my
problem."
paramters in its constructor to allow it to be used to create rotations around a point.
This provides the same interface and functionality as osgUtil::TransformCallback but
has the advantage and AnimationPathCallback is fully supported by the .osg and .ive file formats.
along with support for this Texture1D, 2D, 3D, TextureCubeMap and TextureRectangle. The
new SourceFormat and SourceType parameters are only used when no osg::Image is assigned to
an osg::Texture, and main use is for render to texture effects.
Added support for --hdr option in osgprerender, which utilises the new Texture::setSourceFormat/Type() methods.
readFontStream() to load fonts from a std::istream, rather than from the
local filesystem by name. Such a call may be used, for example, if the
user has a font fetched over a network, or a font available in memory
without a correspondng filename.
The changes implement the new function by following the corresponding code
for readFontFile(). readFontStream() reads a stream into memory, and
holds that memory for FreeType.
As a basic test, I mangled the osgtext example to use
readFontStream(std::ifstream("font")) in lieu of a readFontFile call, and
the modified example ran completely."
SGIX_blend_alpha_minmax and EXT_blend_logic_op extensions. It is
tested with the osgblendequation example. If the extensions are not
supported, a WARN level notification is generated."
the viewport, the clear colour and the subgraph needing rendered. This is done
transparently so all existing functionality will behave as before. What it does
add is the ability to set a SceneView directly by a single osg::CameraNode when required.
into line with OpenGL shader languague conventions.
From Robert Osfield, changed the SceneView::ActiveUnforms enum to from INVERSE_VIEW_MATRIX_UNIFORM
VIEW_MATRIX_INVERSE_UNIFORM to be convistent with the above change.
Fix to the update of the error metrics on the edges in the simplification mesh that are affected by an edge collapse.
Addition of 'n' and 'p' keyboard control in osgsimplifier example to allow users to control the sample ratio manually.
1. type converters created automatically by the I_BaseType macro use
static_cast<> even for base-to-derived conversions. dynamic_cast<> should be
used instead.
2. as a consequence of the above fix, I_BaseType must now differentiate
between polymorphic and non-polymorphic base classes, because the latter
can't be dynamic_cast'd to derived classes. Some template magic (see
is_polymorphic<> in ReflectionMacros) is used to detect polymorphism at
compile time (I'm NOT sure it works on all platforms as it's partly
implementation-dependent. Please test!).
3. predefined custom property getters/setters/counters/etc. (as those
defined for STL containers) only work on Value objects that contain
non-pointer instances. This was an unwanted restriction that no longer
exists.
Wrappers will need to be recompiled. This is a good time to give them a
fresh update with genwrapper.
NOTE: fix#1 should get rid of those crashes and strange behaviours that
some users noticed while using osgIntrospection through osgTcl or in their
own code."
option for using or not using geom's indices for tangent space vectors
generation. now, Ruben's code is also used (it was disabled before). in
order to keep backward compatibility, the compute method behaves as before
in default case."
Spelling fixes in include/osg/LOD
Negated priority in PagedLOD when using _rangeMode==PIXEL_SIZE_ON_SCREEN
Added clampedPixelSize() methods to CullStack and CullingSet to return fabs()ed values.
Changed LOD and PagedLOD ::traverse to use clampedPixelSize() methods.
From Robert Osfield, tweaks of the above to use osg::buffer_object and a local struct to store
initialized to help with multi-thread and out of order context usage.
the intersection between an indivual geometry and the sphere segment.
Converted the terrain in osgspheresegment to be an osg::Geometry based
drawable rather than a osg::ShapeDrawable/osg::HeightField one to make it
more practicle to use as a test for the new SphereSegment intersection code.
the names of the operations to be logged for stats purposes, or used when
do searches of the operation list. The keep member variable tells the graphics
thread run loop wether to remove the entry from the list once its been called.
the position of the emitter in the previous frame and the new position in the new
frame, the number of particles added also scales up to compensate for this movement.
"I've added a Plane constructor which accepts a normal and a point.
I also removed calculateUpperLowerBBCorners() from the Plane(const
Vec3& v1, const Vec3& v2, const Vec3& v3) since the constructor is
using the function set(const Vec3& v1, const Vec3& v2, const Vec3& v3)
which already computes the upper and lower bounding box."
Added osgcamera example that uses osg::GraphicsContext to create the required
window for rendering too, will eventually use osg::CameraNode to replace usage
of osgUtil::SceneView.
"My patch is a slight refactoring of the mac specific code in
Registry.cpp and FileUtils.cpp, specifically around the library and
resource file path initilialization methods. This patch cleans up a
lot of the mac specific code by moving repeated code into separate
local functions in FileUtils.cpp that are only compiled on mac builds.
It also adds one function to the API,
appendPlatformSpecificResourceFilePaths in FileUtils. This function
will mirror the already existing
appendPlatformSpecificLibraryFilePaths except for resource file paths.
Currently this function is empty except when built on the mac, in
which case it will add the application bundle's internal Resources
folder and the bundle's parent folder. Previously this code was
implemented as a separate mac specific #ifdef block in Registry.cpp
around the initDataFilePathList method. However, it now is implemented
in appendPlatformSpecificResourceFilePaths in FileUtils.cpp and the
initDataFilePathList method is now the same on all platforms. This
patch should behave the same as before on non-mac platforms.
This patch already includes the fix that Eric mentioned earlier. This
patch is based off of the 0.99 release code. I have tested this patch
using the following testing scheme:
Make a proper bundled application.
While Run from the Finder:
Test that it finds plugins in its internal plugins path.
Test that it finds resources in its internal resources path.
Test that it finds resources in the bundle's parent directory
Test that it finds plugins in the user's Application Support Directory
Test that it finds plugins in the system's Application Support Directory
Test that it finds plugins in the Network Application Support Directory
Check the plugin and resource path lists after they have been
initialized to see if they are in the correct order
While Run from the command line (both from it's parent directory and
from inside the /Contents/MacOS directory) and repeat the above tests.
Check that it also finds plugins and resources within the paths
defined by various environment variables.
Now, Make an application that is NOT bundled/command line only
Test that it does NOT try to look in an internal bundle
plugin/resource directory for plugins or resources.
Test that it finds plugins/resources in the paths defined by the
environment variables.
"
Added options into osgprerender for controlling how to do the pre rendering i.e.
--fbo, --pbuffer, --fb --window, and also added the option for controlling the
window size with --width and --height.
