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.
the depth of all drawables, so that it is always safe for RenderBin sort routines can use
these values directly.
Add an example of a RenderBin::SortCallback to sgv.cpp.
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.
removal of node which could have been removed.
Added so extra convinience methods to ClippingVolume and utilized them in the
CullVisitor to push and pop only culling planes that are active.
where it automatically resets the near and far to the values calculated
during cull traversal. The maths for converting the computed far and near
into clip coordinates was wrong, fixed this and the problem goes away.
culling to use the pixelSize method instead of a ratio of radius to
distance from eye point. setSmallFeatureCullingPixelSize() method
has also been added to provide the user with finer control of small
featyre culling.
the current projection matrix into CullVisitor itself. Similar code to
support this has been moved out of SceneView completely.
Added Matrix:: infront of the definition of the static
osg::Matrix::inverse(Matrix) method which was missing.
and CullVisitor so that the Viewport is now managed as part as the global
stateset so that it can be pushed and popped like the rest of state without
problems. This makes it easier to have multiple viewports within one
scene graph.
modelview matrix rathan than an identity matrix, this matrix is then modified
locally.
Changed the osg::Matrix set methods so they are inline.
Added a few useful comments to MemoryManager.cpp to help people understand
the assert's better.
which objects have values that vary over the lifetime of the object (DYNAMIC)
and ones that do not vary (STATIC). Removed the equivalent code in
osg::Transform, StateSet and StateAttribute, as these are now encompassed
by the new DataVariance field.
Removed MatrixMode enum from Matrix, and associated fields/parameters from
osg::Transfrom and osg::NodeVisitor, since MatrixMode was not providing
any useful functionality, but made the interface more complex (MatrixMode
was an experimental API)
Added ReferenceFrame field to osg::Transform which allows users to specify
transforms that are relative to their parents (the default, and previous behavior)
or absolute reference frame, which can be used for HUD's, camera relative
light sources etc etc. Note, the view frustum culling for absolute Transform
are disabled, and all their parents up to the root are also automatically
have view frustum culling disabled. However, once passed an absolute Transform
node culling will return to its default state of on, so you can still cull
underneath an absolute transform, its only the culling above which is disabled.
