ExamplesCppCompoundObject

Overview

This example creates a CompoundObject, assigns some data to it and then saves the object to disk as an attribute cache.

Provided the data contained within a CompoundObject is interpolatable itself, then using an InterpolatedCache object to read the object back in will give the expected, interpolated, CompoundObject.

Code

#include <OpenEXR/ImathVec.h>;#include <IECore/CompoundObject.h>;#include <IECore/VectorTypedData.h>;#include <IECore/AttributeCache.h>;usingnamespaceIECore;
intmain( intargc, char*argv[] )
{
//createourcontainerCompoundObjectPtrcontainer( newCompoundObject() );
//createanarrayofintsIntVectorDataPtrint_data( newIntVectorData() );
int_data->writable().push_back( 1 );
int_data->writable().push_back( 2 );
int_data->writable().push_back( 3 );
//createanarrayofV3fsV3fVectorDataPtrvec_data( newV3fVectorData() );
vec_data->writable().push_back( Imath::V3f(1,1,1) );
vec_data->writable().push_back( Imath::V3f(2,2,2) );
vec_data->writable().push_back( Imath::V3f(3,3,3) );
