e51c7f1587 Added support for AbortRendering flag pointer in osg::State which is used 
by osgUtil::RenderLeaf to test if any abort state has been set, if so it
doesn't do any further drawing.

The osgProducer::Viewer has been set up to set the osg::State's it manages
with their AbortRendering flag pointers set to the osgProducer::Viewer::_done
memeber varaible.  Now when escape is pressed the rendering is aborted early.
 2003-03-11 15:25:49 +00:00

image goes out of scope.

Port the image plugins across to specify the new AllocationMode, and converted
them across to using new/delete in place of malloc/free.
 2003-02-25 11:56:18 +00:00

the draw() method has been removed, leaving on the call in SceneView.
 2003-01-24 09:11:05 +00:00

f36bc69c58 Made the more of the OSG's referenced object desctructors protected to ensure 
that they arn't created on the stack inappropriately.

Split the implemention of Matrix up so that it is a simple no referenced counted
class and can be safefly created on the stack.  To support referenced counting a
seperate subclass now exists, this is RefMatrix which inherits from both Matrix and
Object.

Robert Osfield
bfd614f907 Fixed the names of the ControlPoint parameters so they weren't capitals, to avoid 
the clash with the parameter type itself.

Addd a PER_PRIMTIIVE_SET handling to the existing PER_PRIMTIIVE code, this code

Robert Osfield
7d6197441e Added Neil Salter's osgUtx library into the distribution, have put all the 
orignal seperate headers and source into include/osg/UnitTestFrameWork
and src/osg/UnitTestFramework.cpp respectively.  I have done this to
keep the include and source directories focused on the scene graph rather
than the test framework.

Have added a very simple unit test to Vec3.cpp, which are optionally
compiled in with the OSG_COMPILE_UNIT_TESTS define, which is only
currently defined in debug builds under unix.  It should be fine to
add it in under Windows project files as well.

Finally, a new demo app osgunittests runs the tests and reports success
or failure of the tests.
 2002-08-28 14:26:09 +00:00
Robert Osfield
bff4728eac Commented out the #define TEXTURE_USE_DEPRECATED_API from includ/osg/Texture

should have been doing.
 2002-08-22 08:14:38 +00:00
Robert Osfield
c2c6bb5ca6 Moved the include<osg/GLExtensions> from the State header into State.cpp, and

Robert Osfield
22d54f05e4 Added DOFTransform, MatrixTransform and PositionAttitudeTransform to NodeVisitor. 
Added osg::Matrix/Quat::makeRotate(angle1,axis1,angle2,axis2,angle3,axis3) and

Made osg::Matrix/Quat::makeRotate(heading,pitch,roll) and
osg::Matrix::rotate(heading,pitch,roll) all deprecated API.

Fixed the Quat*Quat & Quat*=Quat multiplication methods so that they multiplied
in the correct order - they were reversed originally due to the Quat code being
based on code example which used the v' = M v ordering, rather than the OSG's
v' = v M ordering.

Robert Osfield
29490a8c1c Updates to DOFTransform so that its overrides the traverse() and compute*() methods 
rather than depending upon callbacks for animating and compute matrices.  Merged the
put/inverseput code between Sasa's and Ferndinand's DOF code.

From Bora Utka, Added support to osg::Sequence/OpenFlight AnimNode to the flt plugin.
 2002-08-12 13:42:43 +00:00

7010c1c4f8 Removed dependency of the new osg::DOFTransform and osg::Sequence Node's 
on osgUtil by implementing a NodeVisitor::VisitorType enum, and associated
g/setVisitorType.  This allows callbacks to querry the visitor/traversal
type without doing down cast's to specific visitor subclasses such as
osgUtil::AppVisitor/CullVisitor.
 2002-08-11 21:26:58 +00:00

call dirtyBound() instead of reseting the local bound flag, this ensures
the updates are propagated upwards through into the parents.

b9b013e15b Changed the support for anisotropic filtering in osg::Texture so that it 
is now controlled via the setMaxAnisotropy(float) method, and is set up
independently for the mag filter mode, which it previously was done.

fd788daa69 Added support to StateAttribute/State to support PROTECTED flag for modes and attributes 
so that they cannot be overriden from above via the OVERRIDE flag.  This is
useful for things like manipulators that have handles display in the scene, you
might want to prevent their state being affected by other overriding of
light, wireframe modes etc.

6b59f66d80 Checked in new methods for setting up texture subloading, these allow the 
user to control which parts on an image are subloaded from, and how big
the initial texture is.

05472135b0 Added set/getUnrefImageOnApply() methods and associated flag and 
code in Texture::apply() to set the _image to 0 on apply.  Note,
this will only work when you have a single graphics context, as
with multiple graphics contexts one can't delete the image after
the first apply, as there will be more than one texture object to
update.

3cba9a52ef Updates NEWS file for 0.9.0 release. 
Added default computeBound() implementation to osg::Drawable which uses
a PrimtiveFunctor to compute the bounding box in a generic way, that
will work for all Drawable subclasses that implement the accept(PrimitiveFunctor&).

ff8b4c001d Rewrote the osg::Drawable::AttributeFunctor and PrimtiveFunctor to make 
them more consistent with each other. This does mean an API change, so
dependanct code in the OSG has been updated accordingly.

8036901ea1 Rewrote osg:Statistics so that it is PrimitiveFunctor as is now completely 
decoupled from osg::Drawable.  The Drawable::getStats() virtual method
no longer exists.

Updated the Viewer to use the osg::Statistics incarnation and reformated stats
to clean it up.

7a8eeb3c92 Converted the osg::Material::set/getShininess option to use the standard 
OpenGL range of 0.0 to 128.0 instead of the previous normalised shiniess
range. This brings it inline with the way the rest of the OSG uses a
1 to 1 mapping to OpenGL.

Converted the various loaders to use the new range, which is almost all
cases was simply removing the /128.0f which was required before!

than a GLuint as do previously.

Cleaned up some of the paramters in osg::Vec4.
