ab4398e440 From Farshid Lashkari, "I made a modification to the setClientActiveTextureUnit and 
setActiveTextureUnit methods of osg::State so they return false if the
texture unit is outside the range of allowable units for the driver.
Currently, the functions would return true even if the units are
invalid. This would cause the osg::State to become out of sync with
the actual driver state, which can cause some bugs in certain cases.

The change I made would verify that the unit passed to
setClientActiveTextureUnit is below GL_MAX_TEXTURE_COORDS, and the
unit passed to setActiveTextureUnit is below
max(GL_MAX_TEXTURE_COORDS,GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS). I
modeled this behavior from the OpenGL docs for these commands which
can be found here:

d8ee198735 From John Kelso, 
"Attached are updates of src/osg/Sequence.spp and include/osg/Sequence.

I've taken _sbegin/_send/_ubegin/_uend and _step our of the include file
and made them local variables in whatever method might need them.

I got rid of the _recalculate method as it was only getting used in
one place.

I also found a cut/paste bug in setMode's START case."

Note from Robert Osfield, Also includes some guards against crashes that was occuring in this new
code when handling empty Sequences.

a2ecb93c2b Converted osg::HeightField across to using a osg::FloatArray internally to enable 
it to be assigned as a vertex attribute array to an osg::Geometry.

Removed the osgTerrain::ArrayLayer as its no longer required thanks to the above change
which makes the osgTerrain::HeightFieldLayer more flexible.

Robert Osfield
7013c12a0d From Mike Wittman, "This is another weirdo change to support code generation. It brings all the Drawable::supports and Drawable::accepts overloads into the ShapeDrawable scope to avoid errors invoking the ones that are not defined in ShapeDrawable. Currently you'll get compilation errors if you pass a Drawable::AttributeFunctor or PrimitiveIndexFunctor to the "accept" function invoked on a ShapeDrawable pointer or reference, since those overloads are only defined in the base class. You'll also get the same error passing a PrimitiveIndexFunctor to the "supports" function. These errors occur because C++ function overload resolution does not cross inheritance boundaries." 2007-03-26 13:00:29 +00:00

579700bedf From Mike Wittman, " noticed that some type references of osg::Drawable::AttributeFunctor, osg::Drawable::ConstAttributeFunctor, and osg::StateAttribute::ModeUsage in osg and osgSim were not being properly reflected in osgIntrospection. This appears to be due to Doxygen not handling nested types from superclasses if they're not qualified when referenced in subclasses. 
These changes add the necessary superclass type qualification so that Doxygen now recognizes the references."

526ba8c506 From Stephan Huber, "I added a bool to GraphicsContext::Traits to indicate wether to use the 
multithreaded-opengl-engine on os x or not. I set its default to false,
perhaps other os x users can test this setting with their data/apps, to
see if we can enable it by default.

I changed also the borderless-window-type, so expos?works correctly."

daa54a3b09 From Farshid Lashkari, 
"I've made some changes to osg which I think make it easier to control
the render order of CameraNode's. Instead of using the built-in orders
(PRE_RENDER, POST_RENDER, NESTED_RENDER), you can specify an integer
order. Values less than zero are pre rendered in order. Values greater
than zero are post rendered in order. And a value of 0 is equivalent
to NESTED_RENDER.

The changes should be fully backward compatible. Also, I changed the
RenderStageList type from a vector to a list because I needed to be
able to insert values anywhere in the list.

The reason I made these changes was because I wanted to be able to set
the render order of a CameraNode at runtime without having to reorder
it in the scenegraph."

and later in the final submission message (relating to what has been finally been merged)    :

"I've rethought my implementation and came up with something a little
better. The setRenderOrder will continue to take an enum, but will
have an optional orderNum parameter which can be both positive and
negative. I think this method is more intuitive and flexible."
 2006-09-04 13:15:08 +00:00
Robert Osfield

0900857333 From Farshid Lashkari, 
"I was experiencing hard crashes of my application when using PBO's on
machines that don't support PBO's. I think osg incorrectly checks if
PBO's are supported.

I added a new method to the BufferObject::Extensions class which
returns if the "GL_ARB_pixel_buffer_object" string is supported. This
fixes the problem on my end. Machines without PBO support will
continue to work and machines with PBO support will still be able to
use it."

Robert Osfield
62edacece5 From David Guthrie, "I know there are 50,000 changes to osg/Math for OSX a day, but I 
think it can be simplified quite a bit.  The old code includes
<cmath> for pre-10.2 and anything using something other than g++ 4
and then uses std::isnan.  For the most current version, it leaves
out cmath and uses isnan().  std::isnan and cmath work for the
current version, so I just made it include cmath if __APPLE__ is
defined and removed the ifdef between versions of OS X for isnan
related things.

This way the code is all the same, and it's not fragile to someone
including <cmath> prior to including osg/Math."

be60b32add Fixed texture optimization problem associated with mixing already compiled scene graphs - resulting

"Attached is some fixes for Image::readImageFromCurrentTexture. It was
failing when used with a new Image object (some of the fields were

A new optional parameter was added to give the desired data type, which
defaults to GL_UNSIGNED_BYTE, so programs should only need a recompile
to work properly."

Robert Osfield
43f0efd6d2 Reorganised the Group::removeChild and Geode::removeDrawable methods so 
that removeChild(Node*), removeChild(uint) and equivilant Geode methods are
now inline methods, not designed to be overriden, and seperated out the
multiple remove method to be called removeChildren(uint, uint) which is
now the only virtual method.  There removeChildren is now the method to
override in subclasses.

This reorganisation requires some call code to be rename removeChild usage
to removeChildren.

2b61cf0a1e From Farshid Lashkari, "The following patch adds a multisample option to the 
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."

25abad8307 From Paul Martz, "I've attempted to make AutoTransform override computeBounds() to return 
an invalid bounding sphere if it hasn't seen a cull traversal yet. It

after a cull. There might be a better way? If so, let me know.

83d492162e Added the support in AnimationPathCallback for taking a pivot, axis and rotation rate 
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.

53e075f78b From Brad Colbert/Robert Osfield: added s/getSourceFormat and s/getSourceType to osg::Texture 
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.
