MWRender::AlphaFader::AlphaFader ( float *  alphaUpdate )

inline

Parameters

alphaUpdate

variable which to update with alpha value

Member Function Documentation

virtual void MWRender::AlphaFader::apply ( osg::StateSet *  stateset, osg::NodeVisitor *  nv  )

inlinevirtual

Apply state - to override in derived classes

Note

Due to the double buffering approach you have to apply all state even if it has not changed since the last frame.

Reimplemented from SceneUtil::StateSetUpdater.

Reimplemented in MWRender::RainFader.

Here is the caller graph for this function:

void MWRender::AlphaFader::setAlpha ( float  alpha )

inline

virtual void MWRender::AlphaFader::setDefaults ( osg::StateSet *  stateset )

inlinevirtual

Set default state - optionally override in derived classes

May be used e.g. to allocate StateAttributes.
