class | osg::Node |
class | osg::Drawable |
class | osg::Uniform |
class | osg::StateAttribute |
Stores a set of modes and attributes which represent a set of OpenGL state.
Notice that a StateSet
contains just a subset of the whole OpenGL state.
In OSG, each Drawable
and each Node
has a reference to a StateSet
. These StateSet
s can be shared between different Drawable
s and Node
s (that is, several Drawable
s and Node
s can reference the same StateSet
). Indeed, this practice is recommended whenever possible, as this minimizes expensive state changes in the graphics pipeline.

By default render bins will be nested within each other dependent upon where they are set in the scene graph.
This can be problematic if a transparent render bin is attached to an opaque render bin which is attached to another transparent render bin as these render bins will be sorted separately, giving the wrong draw ordering for back-to-front transparency. Therefore, to prevent render bins being nested, call setNestRenderBins(false).

void osg::StateSet::setRenderBinDetails | ( | int | binNum, |
const std::string & | binName, | ||
RenderBinMode | mode = USE_RENDERBIN_DETAILS |
||
) |
Set the render bin details.
|
inline |
Set the render bin mode.
void osg::StateSet::setRenderBinToInherit | ( | ) |
Set the render bin details to inherit.
void osg::StateSet::setRenderingHint | ( | int | hint | ) |
Set the RenderingHint
of this StateSet
.
RenderingHint
is used by the renderer to determine which draw bin to drop associated osg::Drawable
s in. Typically, users will set this to either StateSet::OPAQUE_BIN
or StateSet::TRANSPARENT_BIN
. Drawable
s in the opaque bin are sorted by their StateSet
, so that the number of expensive changes in the OpenGL state is minimized. Drawable
s in the transparent bin are sorted by depth, so that objects farther from the viewer are rendered first (and hence alpha blending works nicely for translucent objects).
void osg::StateSet::setTextureAttribute | ( | unsigned int | unit, |
StateAttribute * | attribute, | ||
StateAttribute::OverrideValue | value = StateAttribute::OFF |
||
) |
Set this StateSet to contain specified attribute and override flag.
void osg::StateSet::setTextureAttributeAndModes | ( | unsigned int | unit, |
StateAttribute * | attribute, | ||
StateAttribute::GLModeValue | value = StateAttribute::ON |
||
) |
Set this StateSet to contain specified attribute and set the associated GLMode's to specified value.
|
inline |
void osg::StateSet::setTextureMode | ( | unsigned int | unit, |
StateAttribute::GLMode | mode, | ||
StateAttribute::GLModeValue | value | ||
) |
|
inline |
|
virtual |
Set whether to use a mutex to ensure ref() and unref() are thread safe.
Reimplemented from osg::Object.
|
inline |
set the list of all Uniforms contained in this StateSet.
Set the Update Callback which allows users to attach customize the updating of an object during the update traversal.
|
inline |
Get whether the render bin details are set and should be used.
