Detailed Description

Visitor that locates effect textures and installs them into the scene graph.

Run this prior to running the Shader Generator to pick up normal maps, reflectivity maps, specular maps, ambient occlusion maps, and emissivity maps.

Member Function Documentation

void makVrv::DtOsgEffectTextureVisitor::reset

(

)

Resets the visitor to its initial state.

If you plan to use the same instance more than once, call reset() before each use.

unsigned makVrv::DtOsgEffectTextureVisitor::getNumEffectTexturesInstalled

(

)

const

After visiting, call this to see how many effect textures the visitor installed.

Calling reset() will reset this to zero.

bool makVrv::DtOsgEffectTextureVisitor::isEffectTexture

(

osg::Texture *

tex

)

const

Checks whether a texture is an effect texture.

virtual bool makVrv::DtOsgEffectTextureVisitor::checkAndSetIgnoreHint ( osg::Object *  obj, bool  val  )

virtual

Set the state of the ignore hint for a node Updated to be threadsafe and check the current value and set it in one call.

It returns the previous value of the ignore flag and changes it to be val. Use this to mark nodes as ignored for future texture finding traversals

virtual void makVrv::DtOsgEffectTextureVisitor::setIgnoreHint ( osg::Object *  obj, bool  val  )

virtual

Set the state of the ignore hint for a node Updated to be threadsafe Use this to mark nodes as ignored for future texture finding traversals.
