1219a6d3bf Added more osg::Object::as*() methods and usage of these through the code base to avoid use of dynamic_cast<> when using UpdateVisitor/CullVisitor/EventVIisitor etc. 2016-01-20 15:13:19 +00:00

7409820a8f Added Simplifier::requiresDownSampling()/requiresDownSamplingImplementation() to make it possible for the
Simplfifer::ContinueSimplificationCallback to be able to decide whether up or downsampling is required,
removing the previous hardwards reliance on getSampleRatio<1.0.

dd996a3289 Introduced CMake option OSG_PROVIDE_READFILE option that defaults to ON, but when switched to OFF disables the building of the osgDB::read*File() methods,
forcing users to use osgDB::readRef*File() methods.  The later is preferable as it closes a potential threading bug when using paging databases in conjunction
with the osgDB::Registry Object Cache.  This threading bug occurs when one thread gets an object from the Cache via an osgDB::read*File() call where only
a pointer to the object is passed back, so taking a reference to the object is delayed till it gets reassigned to a ref_ptr<>, but at the same time another
thread calls a flush of the Object Cache deleting this object as it's referenceCount is now zero.  Using osgDB::readREf*File() makes sure the a ref_ptr<> is
passed back and the referenceCount never goes to zero.

To ensure the OSG builds when OSG_PROVIDE_READFILE is to OFF the many cases of osgDB::read*File() usage had to be replaced with a ref_ptr<> osgDB::readRef*File()
usage.  The avoid this change causing lots of other client code to be rewritten to handle the use of ref_ptr<> in place of C pointer I introduced a serious of
templte methods in various class to adapt ref_ptr<> to the underly C pointer to be passed to old OSG API's, example of this is found in include/osg/Group:

    bool addChild(Node* child); // old method which can only be used with a Node*

    tempalte<class T> bool addChild(const osg::ref_ptr<T>& child) { return addChild(child.get()); } // adapter template method

These changes together cover 149 modified files, so it's a large submission. This extent of changes are warrent to make use of the Object Cache
and multi-threaded loaded more robust.

a331680cec From Aurélien Chatelain, "the smoothing visitor did not handle shared arrays. It may leads to bad geometry arrays when a shared array is involved in the scene.
This submission adds shared array duplication (and moves the SharedArrayOptimizer declaration in MeshOptimizer to make it callable from the SmoothingVisitor)."

Submitted by Marc Helbling.
Edited by Robet Osfield to retain the usual OSG coding style.

58c47e9842 From Marc Helbling, "please find enclosed a submission that should improve the VertexAccessOrderVisitor (pre-transform) optimizer:
* it sorts primitives to keep "more complex" primitives first; maybe you'll prefer to have this as an option (but usually it should make more sense to pre-transform triangles before e.g. lines)
* currently, the visitor rely on TriangleIndexFunctor and does not take care of points and lines (see https://github.com/openscenegraph/osg/blob/master/include/osg/TriangleIndexFunctor#L124-130). This can lead to issues e.g. if you store the wireframe lines along with some triangles: the triangles will be reindexed but not the line. I've therefore added osg/include/TriangleLinePointIndexFunctor to index triangles, lines and points and derived VertexReorder from this class.
* to avoid issues, shared arrays are duplicated. However, in some cases (e.g. an UV channel shared in the geometry only) this is not required. I'm adding a SharedArrayOptimizer to optimize this: it looks for duplicated UVs before the array duplication and deduplicate arrays after.

117869d154 From Marc Helbling, "please find the mergeTriangleStrip code merged in osgUtil::TriStripVisitor.
I've removed the references to DrawArrays as we should no longer produce any.

Note that:
* as the name suggest, it only works for triangle strips but could probably be easily extended to quads
* the resulting primitive is not highly optimized; we could probably sort the strips in order to minimize the number of primitive restart
* as we may merge DrawElementsUInt and DrawElementUShort, the code will only generate DrawElementsUInt"

b2c7bacfe9 From Farshid Lashkari, "As discussed, I've added the ability to handle Drawable objects within the NodeVisitor class. Here is an overview of the changes:
- Added apply(Drawable) and apply(Geometry) to NodeVisitor

- Added accept(NodeVisitor) method to Drawable/Geometry

- Added traverse(NodeVisitor) to Geode which calls accept(NodeVisitor) on all Drawables

- Updated CullVisitor to use new apply(Drawable) to handle drawables. The apply(Billboard) method still manually handles the drawables since it is depends on the billboard settings. I needed to disable the traverse within billboard to prevent duplicate traversal of drawables.

- Update other osgUtil node visitors (GLObjectsVisitor, IncrementalCompileOperation, ..) to use new apply(Drawable) method.

f537ece404 From Leandro Motto Barros,
"I've made a few changes to osgUtil::PolytopeIntersector so that it
actually uses double precision floating point numbers everywhere (as
long as OSG_USE_FLOAT_PLANE is not defined).

I needed double precision intersections in a project I am working on.
These changes fixed the problems I was having -- this is all testing I
have done.

Notice that I have changed
osgUtil::PolytopeIntersector::Intersection's members to use doubles
(osg::Vec3d, instead of osg::Vec3). I could have added #ifdef's there
too, but I think it is better to not change the types of stuff in the
public interface depending on some preprocessor definition.

The modified files are attached. A diff also follows, for those who like it."

With the following changes from Robert Osfield:

"I've just reviewed your changes and have just tweaked them a little to
streamline them.  What I have done in the PolytopeIntersector header
is add:

       typedef osg::Plane::Vec3_type Vec3_type;

And then use this typedef in the definition of the vertices rather
then Vec3d as you did.  Next changes were to PolytopeInteresector.cpp
where to the PolytopeIntersectorUtils defintions of the Vec3_type, and
value_type which now simply read:

   typedef osg::Plane::Vec3_type Vec3_type;
   typedef Vec3_type::value_type value_type;

This way I was able to complete avoid any if def's and have essential
the same implementation as you achieved.  Changes now checked into
svn/trunk."

52270c9656 From David Fries, "Of the two ways to use the Tessellator object, only
retessellatePolygons was applying the winding and boundary option.
Moved the gluTessProperty calls into beginTessellation().

There's a comment typo fix, removing an unused VertexPointList
typedef, and allocates one _tobj instead of one per tesellation.
Protections were added to check that _tobj was allocated in the few
remaining places it wasn't being checked.

---
On a side note, I would like to avoid the 'new Vec3d' in
Tessellator::addVertex for each call to
gluTessVertex(tess, location, data).
The RedBook leaves it ambiguous if the location pointer must
remain valid after gluTessVertex or not.
http://www.opengl.org/sdk/docs/man/xhtml/gluTessVertex.xml
says that changing location is not safe, so being conservative, I'll
leave it as is, even though the Mesa GLU library copies the data not
the pointer, so it is currently safe."

147fdd0430 From Sukender, "1. More handled cases in MergeGeometryVisitor
- Algorithm doesn't try to merge double and single precision arrays together
- Algorithm doesn't try to merge incompatible geometries (ex: one with "vertices + texoords", and another with only vertices)

2. Better TextureAtlasBuilder
Algorithm is still sub-optimal, but it now tries to fill more blanks, using "unused space in the current line".
(Don't know if I already submitted it, but I guess not)
One day, someone should try to find a good solution to this NP-problem... For instance : http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.140.200&rep=rep1&type=pdf

b55f75111e Added support for using a custom osg::Geometry that attempts to force the OpenGL driver
to download the texture object to graphics card.

Calling IncrementalCompileOperation::assignForceTextureDownloadGeometry() assigns a geometry
to the job.

7c38643a77 From Tim Moore, "I noticed that the "Materials" statistic in the camera scene stats display seemed to be identical to the number of drawables. In fact, it displays the nummat member of osgUtil::Statistics, but that variable has nothing to do with materials. nummat tracks the number of matrices associated with Drawable objects in a RenderBin; as I understand it, Drawables pretty much always have a model-view matrix tied to them in RenderBins, so this statistic doesn't seem very useful. So, I added statistics for the number of StateGraph objects in RenderBins and also for the number of Drawables in the "fine grain ordering" of RenderBins. The latter corresponds to the number of Drawables in the scene that are sorted by some criteria other than graphics state; usually that is distance for semi-transparent objects, though it could be traversal order. These two statistics give an idea of the number of graphic state changes happening in a visible scene: each StateGraph implies a state change, and there could be a change for each sorted object too. You can also subtract the number of sorted Drawables from the total number of Drawables and get an idea of how many Drawables are being drawn for each StateGraph.

b1658ee6df From Farshid Lashkari, "I noticed that osg::State::getInitialViewMatrix returns the monocular view matrix when rendering in stereo. I've made some changes to osgUtil::RenderStage & SceneView so that it will return the correct view matrix depending on which eye is currently being rendered." & "I made a small change to the previous patch so that osg::State::getInitialViewMatrix works correctly with pre/post render stages as well." 2010-04-19 14:49:42 +00:00

7a44b43474 From Time Moore, "This submission implements 3 optimizations for meshes. INDEX_MESH turns DrawArrays style geometry into DrawElements, uniquifying the vertices in the process. This is useful for certain loaders, like ac3d, which just spit out DrawArrays. VERTEX_POSTTRANSFORM and VERTEX_PRETRANSFORM optimize mesh triangle and vertex order for the caches on a modern GPU, using Tom Forsyth's algorithm. I describe this and the big difference it makes (38% improvement on a very large mesh) in my blog,

3f65f4f80b From Wojciech Lewandowski, support for FBO's without colour or depth attachments.
Note from Robert Osfield, I've temporarily re-enabled the old focing of of color and depth attachment to avoid regressions on some OpenGL driver.  We'll revist this once
we have a mechanism for controlling this override at runtime.

aa69137fb8 Added collateReferencesToDependentCameras() and clearReferencesToDependentCameras() methods into RenderStage and SceneView, and use
of these methods in src/osgViewer/Renderer.cpp to make sure that the draw thread keeps references to all in scene graph Cameras
that are being used by the drawing threads, to keep the Camera's alive even when the main thread removes these Cameras from the scene graph.
