custom operators and changing topology

Hi

I'm trying to read geometry (from a stream) using a custom operator.

as long as there's no topology changes all works fine and the mesh is read and animated.

when the topology changes softimage crashes.

I understand I need to classify that operator siClassifTopo, but not sure how to do that in c++

(the c++ methods for CreateParamDef in factory don't have the option to specify the classification that the object model has).

what would be the right way to go about it?

Cheers

Ran

XSIFactory.CreateParamDef() is for creating parameters the user interacts with in the operator’s PPG.

Defining the data type your operator reads/writes is done via port connections. CustomOperator.AddInputPort() and CustomOperator.AddOutputPort(), for example.

Thank you Matt

the issue is not defining the data type, the problem I'm facing is trying to let softimage treat my customOperator as one that is changing topology.

one of the advice I found online was defining the first parameters on that operator as "siClassIfTopo", that method is valid for the object model but not in the c++ signature.

Scripting and C++ are not 1:1. It might not be necessary to set parameter classification to ‘siClassifTopo’ in C++.

I don’t know the answer.

I’m on 2013 SP1, but those new methods are not shown in the SDK manuals. I think they were added in 2014.

Hi Ran,

Which Softimage version are you using?

Since 2013 SP1, there’re two new C++ APIs introduced, to allow the creation of paramdef with a specified classification.

1. Factory::CreateParamDef

CreateParamDef (const CString &in_scriptname, CValue::DataType in_type, siParamClassification in_classification, INT in_capabilities, const CString&in_name, const CString &in_description, const CValue &in_default, const CValue &in_min, const CValue &in_max, const CValue &in_suggestedmin, constCValue &in_suggestedmax, CStatus *pst=0)

2. CustomProperty::AddParameter

AddParameter (const CString &in_scriptname, CValue::DataType in_type, siParamClassification in_classification, INT in_capabilities, constCString &in_name, const CString &in_description, const CValue &in_default, const CValue &in_min, const CValue &in_max, const CValue&in_suggestedmin, const CValue &in_suggestedmax, Parameter &io_parameter)

Thanks,

Joany

Hi Matt,

We didn't update docs for service pack release.

You can see their introduced version is v11.1(2013) in 2014 sdk manual.

11.1 means 2013 SP1.

Thanks,
Joany

For the record, SDK updates like this are pretty important. I would like to request the docs be updated with reach release whether it be a main release, service pack, or subscription advantage pack.

In this particular scenario, if I had to write the custom topology operator, I would be following the 2013 SP1 documentation only to encounter errors from improper use (because SDK doesn’t match the manuals), or would pull out hair wondering why my operator is behaving in a flakey manner.

It’s important the documentation be matched with the software we’re using.

Thank you.

Hi Matt,

Thanks for your comments. We will work with doc team to see what’s going on if there are sdk changes in SP.
Normally, in SP release, SDK wouldn’t be changed except the bug fixing (But support backward-compatibility).
This is very particular/rare case that happened in 2013 SP1.

Back to this question, you may try to use CComAPIHandler, to call APIs provided by Object Model.

Joany
