Detailed Description

Reads data from a geometry file.

The ReadGeo creates one of these for each file it reads. Each different file type is a different subclass. Each subclass defines a Reader_Description object, all of these are searched to figure out what subclass to use.

The base class for GeoReader both provides default implementations and serves as the "NullReader" that is used when the type cannot be figured out.

Constructor & Destructor Documentation

GeoReader()

GeoReader::GeoReader

(

ReadGeo *

i

)

Subclasses should have constructors that match Reader_Description::constructor.

~GeoReader()

GeoReader::~GeoReader ( )

virtual

The destructor must close any files (even though the ReadGeo may have opened them).

Member Function Documentation

_open()

void GeoReader::_open ( )

virtual

This is called before the first call to geometry_engine(). It should do any expensive setup.

filename()

const char * DD::Image::GeoReader::filename ( ) const

inline

The filename

readTextureWCoord()

bool DD::Image::GeoReader::readTextureWCoord ( )

inline

read texture texture w coord

References DD::Image::ReadGeo::readTextureWCoord().

enableAxisKnob()

virtual bool DD::Image::GeoReader::enableAxisKnob ( )

inlinevirtual

enable the axis knob or knot for the current plugin This is a temporary hack fix until per-mesh animation over-rides can be introduced.

get_geometry_hash()

virtual void DD::Image::GeoReader::get_geometry_hash ( Hash *  geo_hash )

pure virtual

Get the geometry hash.

Referenced by DD::Image::ReadGeo::get_geometry_hash().

knob_changed()

virtual int DD::Image::GeoReader::knob_changed ( Knob *  k )

pure virtual

Implements the knob_changed callback for readers.

_validate()

virtual void DD::Image::GeoReader::_validate ( const bool  for_real )

pure virtual

Implements the _validate callback for readers.

append()

virtual void DD::Image::GeoReader::append ( Hash &  newHash )

pure virtual

Has the state chnaged?

default_material_iop()

virtual Iop * DD::Image::GeoReader::default_material_iop ( ) const

inlinevirtual

Default material
