◆ PrintSelf()

void vtkOSPRayMaterialLibrary::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

◆ Fire()

void vtkOSPRayMaterialLibrary::Fire ( )

Called to kick off events in all followers.

◆ ReadFile()

bool vtkOSPRayMaterialLibrary::ReadFile ( const char *  FileName)

Reads the given file of materials and creates the in memory data structures needed to display objects with them.

Returns false only if file could not be meaningfully interpreted.

◆ WriteBuffer()

const char * vtkOSPRayMaterialLibrary::WriteBuffer ( bool  writeImageInline = true)

Serialize contents to an in memory buffer.

If writeImageInline, all textures are stored in a XML format. Else, store the texture using its filename stored in its TextureInfo struct. Warning: you must free the return value using delete.

◆ WriteFile()

void vtkOSPRayMaterialLibrary::WriteFile ( const std::string &  filename,
bool  writeImageInline = false 
)

Serialize contents to a file specified by filename.

If writeImageInline, all textures are stored in a XML format. Else, store the texture using its filename stored in its TextureInfo struct Warning: if filename exists, its content is discarded.

◆ ReadBuffer()

bool vtkOSPRayMaterialLibrary::ReadBuffer ( const char *  Buffer)

DeSerialize contents from an in memory buffer as ReadFile does from a file or set of files.

Returns false only if buffer could not be meaningfully interpreted.
