Detailed Description

This is a two-passes effect; the first pass renders the subgraph as usual while the second pass switches to wireframe mode, sets up lighting and material to obtain a fixed (user-defined) color and then renders the subgraph.

This effect uses the PolygonOffset attribute to avoid Z-fighting, so it requires at least OpenGL version 1.1.

bool osgFX::Scribe::define_techniques (   )  [protected, virtual]

abstract method to be implemented in derived classes; its purpose if to create the techniques that can be used for obtaining the desired effect. You will usually call addTechnique() inside this method. Implements osgFX::Effect.

const osg::Vec4 & osgFX::Scribe::getWireframeColor (   )  const [inline]

get the wireframe color

float osgFX::Scribe::getWireframeLineWidth (   )  const [inline]

get the wireframe line width
