5b60708e80 From Sebastian Messerschmidt, "There was some small error due to MS non-conformity handling comments correctly." 2014-05-15 14:57:28 +00:00
Robert Osfield
20b9f3ff88 Added Node::asDrawable() and Node::asGeometry() methods to provide a low cost way of casting a node to Drawable and Geoemtry.
Changed the Group::computeBound() method so that it takes account of the a Drawable's BoundingBox.

12a737ae02 Changed the Node::ParentList to be a list of osg::Node rather than osg::Group, and added addChild, removeChild, replaceChild virtual method to Node to enable code
to user code compile with minimal modifications to account for the new change to the Node ParentList.

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.

2bb4e0566c From Pjotr Svetachov, "I had the osgvolume example crash on me when loading large volume
datasets due to an overflow in image.cpp after a unneeded cast from
unsigned int to int. Here is a small fix."

4994b806d2 From Pjotr Svetachov, "For me osgviewer.cpp and Renderer.cpp were not compiling (visual studio 2013 with profile GL2) because they were still using GLuintEXT. So I changed that, see the attached files.
I also noticed that the generated OpenGL header were not copied to the installation directory so my own application could not find it."

77f1c58345 From Lionel Lagarde, "In the ::apply method, when the image data need to be re-uploaded, the Texture2DArray checks if the TextureObject can be re-used. The test was made using the constant 1 instead of the real texture depth, so the TextureObject was never re-used." 2014-04-24 17:23:16 +00:00

a1342a6bf6 Added src/osg/OpenGL.in configuration file and include/osg/OpenGL header files 2014-04-23 19:30:33 +00:00
Robert Osfield
5597248895 Introduced new scheme for setting up which version of OpenGL/OpenGL ES the OSG is compiled for.
To select standard OpenGL 1/2 build with full backwards and forwards comtability use:

  ./configure
  make

OR

  ./configure -DOPENGL_PROFILE=GL2

To select OpenGL 3 core profile build using GL3/gl3.h header:

  ./configure -DOPENGL_PROFILE=GL3

To select OpenGL Arb core profile build using GL/glcorearb.h header:

  ./configure -DOPENGL_PROFILE=GLCORE

To select OpenGL ES 1.1 profile use:

  ./configure -DOPENGL_PROFILE=GLES1

To select OpenGL ES 2 profile use:

  ./configure -DOPENGL_PROFILE=GLES2


Using OPENGL_PROFILE will select all the appropriate features required so no other settings in cmake will need to be adjusted.
The new configuration options are stored in the include/osg/OpenGL header that deprecates the old include/osg/GL header.

5f8e2bda2f Added osg::CallbackObject to be used to extend C++ class from scripting languages by providing callback objects assigned to the osg::Object UserDataContainer, with the CallbackObject's Name used to map the "method" provided by the CallbackObject. The CallbackObject is implemented by the script engine to provide the neccessary glue to invoking the script with the appropriate input parameters and handling the output parameters.
To the Lua plugin added support for assigned lua functions to C++ osg::Objects via the new osg::CallbackObject mechanism.  To invoke the scripts function from C++ one must get the CallbackObject and call run on it.

Renamed ScriptCallback to ScriptNodeCallback to avoid possibly confusion between osg::CallbackObject and the ScriptNodeCallback.

5292c7ca50 From Laurens Voerman, "I experienced a crash in Geometry::fixDeprecatedData(), on certain files, and brought the problem down to a very simple test file, attached as test3.zip.
There are two problems:
1> for DrawElementsUShortPrimitiveType (and UInt) the source_pindex still equals -1 and causes a crash
     in DrawElementsUBytePrimitiveType source_pindex is incremented, and in DrawElementsU(Short/Int)PrimitiveType primitiveNum is incremented, but never used

2> The drawelements need to be rewritten as the vertices are reordered.

created a patch for osg stable branch(r14038): attached as Geometry-osg-3.2.zip
and for svn brach(r14044): attached as Geometry_osg_svn.zip"

70bfad0371 From Aurelien Albert, "In the "apply" method of osg::FrameBufferObject, the draw buffers are always enabled, even if the target is only "READ_FRAMEBUFFER".
This can lead to inconsistency if you bind a framebuffer with multiple attachments in DRAW mode and then a framebuffer with different attachment count in READ mode (for example to manually "blit" from a FBo to another).

On some ATI cards (at least RADEON HD) this also leads to an "incomplete " FBO status

I've added a test to enable drawbuffers only if target is "DRAW" or "READ_DRAW", this solves my problems on ATI cards."

d8482ef1ba From Kristofer Tingdahl,"we have a bunch of classes that inherit osg::Node, and they create their own, internal geometry which is passed into the render bucket at the cull-traversal. Last week, we realised that these classes are not accounted for when doing an ComputeBoundVisitor- traversal, as there is no specialization in ComputeBoundVisitor for them.
One solution is naturally to create a new class that would inherit the osg::ComputeBoundVisitor, and use that. I don't like that idea as the ComputeBoundVisitor does actually have what I need - it is only hidden in a protected function.

I am therefor suggesting a slight generalization of the ComputeBoundVisitor with the attached patch, which is tested.

The patch has two parts:
we add applyBBox() so that one can use that in a customized traverse-function and add a bbox to the visitor. I considered calling this function expandByBBox(), but I though  applyBBox was better.
The MatrixStack is made available to the outside world. That enables a traverse-function to do whatever it wishes.
I do actually only need one of the two, as I can implement what I wish either way, but adding getMatrixStack() will make more generic expansions possible.
"

From Robert Osfield, changed the name of the new applyBBox(..) method to applyBoundingBox(..) to keep it's naming more consistent with the rest of the OSG.

c45f3aa4fb Merged changes to DisplaySettings from Stephan Huber in prep for controlling the menu hiding behaviour under OSX.
Added new WindowSystemInterface::setDisplaySettings() method to provide a mechanism for passing settings onto the WindowSystemInterface so it can then set up the system appropriately.

Added assignment of the DisplaySettings to the WindowSystemInterface in Viewer/ComppsiteViewer::realize().

68c22efa58 From Thomas Hogarth, "Attached is a small build fix for PointSprite when compiling under GLES2 (r13788)
GL_POINT_SPRITE_OES does not exist in GLES2, instead you just draw using GL_POINTS then use gl_PointSize in a vertex shader to set the size."

d304ed7d73 From Farshid Lashkari, "I have a scene that makes heavy use of the StateSet::compare method and my profiler showed that a lot of time was being spent inside it. I made a small change to the method so that it performs a quick size comparison between the attribute/mode lists and bin mode before iterating through all the attributes. This made a noticeable improvement in my scene. I've attached the change." 2013-09-30 18:15:51 +00:00

e9697859bd From Colin McDonald, "Add test for GL_EXT_framebuffer_object extension : osg uses osg::FBOExtensions to check if Frame Buffer Objects are
available.  But this just checks if the fbo functions can be called.
It doesn't check if the OpenGL renderer supports fbos.  For indirect
rendering on linux the client side capability may be different from
the display server, which can lead to mipmapped textures failing to
render.  I've added a fbo extension check.

df48d440e4 From Colin McDonald, "Attached are some fixes to build osg using the Solaris Studio compiler.
I've also checked the modified files still build ok with other
compilers (Linux gcc, Windows Visual Studio).

osgDB/OutputStream.cpp and osgPlugins/lws/SceneLoader.cpp require
stdlib.h for atoi use.

In osg/Uniform.cpp the compiler complains that base_class is unknown
unless I add a class name qualifier.

Not a build fix, but I spotted a typo in osgUtil/SceneView."

bd7ec9c5f7 Added initial cut of basic scripting support, introducing an osg::Script object to wrap up the individual scripts, osg::ScriptCallback for assigning a Script as node callback and an osg::ScriptEngine base class that plugins implement to provided support for specific scripting languages.
Provided are lua, python and V8 (for javascript) plugins that just open up enough of a link to the respective libs to run a script, there is no scene graph <-> script communication in current implementation.

837a680849 From Tom Jolley, "I found a couple more bugs after closely looking at the small piece of deprecated geometry in my model. There were problems with more than one primitive in a couple places. The first was the number of vertices were not being accumulated for DrawArraysPrimitiveType (caused another crash). The second is I had to move target_vindex and source_pindex before the PrimitiveSetList loop so they don't get reset on the next primitive (otherwise you end up with a lot of zeros in per vertex lists)." 2013-08-01 10:00:31 +00:00
