As always writing to the list and a quick bike ride are a cure to all
softimage related ailments.
For anyone coming upon this on a google search, here is the code that got
it to work:
(This is just the code from the Evaluate callback.)
case ID_OUT_DecPointPositionArray :
{
// Get the output port array ...
CDataArray2DVector3f outData( in_ctxt );
// Get the input data buffers for each port
CDataArray2DCustomType EncodedGoalData( in_ctxt, ID_IN_EncodedGoalArray );
// We need a CIndexSet to iterate over the data
CIndexSet indexSet( in_ctxt );
for(CIndexSet::Iterator it = indexSet.Begin(); it.HasNext(); it.Next())
{
// Add code to set output port...
CDataArray2DCustomType::Accessor EncodedGoalDataSubArray =
EncodedGoalData[it];
GoalData* pBufferEncodedGoal;
ULONG nSizeEncodedGoal;
EncodedGoalDataSubArray.GetData( it,(const
CDataArray2DCustomType::TData**)&pBufferEncodedGoal, nSizeEncodedGoal );
CDataArray2DVector3f::Accessor outDataSubArray = outData.Resize(it,
EncodedGoalDataSubArray.GetCount());
for (ULONG i=0; i<EncodedGoalDataSubArray.GetCount(); i++)
{
if (nSizeEncodedGoal)
{
outDataSubArray[i].PutX(pBufferEncodedGoal->PointPosition.GetX());
outDataSubArray[i].PutY(pBufferEncodedGoal->PointPosition.GetY());
outDataSubArray[i].PutZ(pBufferEncodedGoal->PointPosition.GetZ());
}
else
{
outDataSubArray[i] = MATH::CVector3f( 0, 0, 0 );
}
}
}
}
break;
Have a good evening everyone!
