Detailed Description

Abstract class to look in the stateset and collect textures specified via its template The effect texture visitor installs effect textures during loading Indirect rendering needs to know which effect textures these are (so it can install its indirect rendering based shaders, etc).

These are slightly different in case of point features, cdb, etc This abstract class allows you to handle these abstractly

Member Function Documentation

virtual void makVrv::DtIndirectTextureCollectionPolicy::collectTextures ( DtIndirectGeometryTextures *  texturePointers, const osg::StateSet *  stateSet, const std::string &  modelName  ) const

pure virtual

inherited class must implement the found textures go into texturePointers pass in the model name to improve the error messages

Implemented in makVrv::DtIndirectDefaultTextureCollectionPolicy, and makVrv::oe::CDB::DtCDBTextureCollectionPolicy.

virtual const DtIndirectEffectTexturesTemplate& makVrv::DtIndirectTextureCollectionPolicy::effectTexturesTemplate ( void  ) const

virtual

access the template

virtual const std::string& makVrv::DtIndirectTextureCollectionPolicy::glslTextureDeclarationHashDefine ( const DtIndirectEffectTexturesTemplate &  effectTexturesState ) const

pure virtual

access the the texture declaration (effectively the texture declaration in the shader) The types of effect textures are different in the case of cdb vs point features vs byo Therefore, the corresponding texture structure declarations used by the indirect rendering shaders are different.

This function abstractly allows you to query the declarations in each policy type. This texture declaration is built off of the corresponding DtIndirectEffectTexturesTemplate which is different in each concrete policy type

Implemented in makVrv::DtIndirectDefaultTextureCollectionPolicy, and makVrv::oe::CDB::DtCDBTextureCollectionPolicy.

virtual void makVrv::DtIndirectTextureCollectionPolicy::printHashDefineDetails ( const DtIndirectEffectTexturesTemplate &  effectTexturesState ) const

pure virtual

Implemented in makVrv::DtIndirectDefaultTextureCollectionPolicy, and makVrv::oe::CDB::DtCDBTextureCollectionPolicy.

virtual std::string makVrv::DtIndirectTextureCollectionPolicy::hashKey ( const DtIndirectEffectTexturesTemplate &  effectTexturesState ) const

virtual

utility for creating a hash key from a textures template
