Detailed Description

Converter class to transform MaterialX document objects into Protobuf MaterialXDocument messages.

• Traverses the MaterialX document structure and constructs the corresponding Protobuf message hierarchy.
• Handles attributes and child elements recursively.
• Usage: MaterialXToProtobuf converter; MaterialXDocument pb_doc = converter.convert(mx_doc);
• Where mx_doc is a MaterialX document pointer.

convertElement()

MaterialXElement MaterialXToProtobuf::convertElement ( mx::ElementPtr mx_elem )

private

Parameters

mx_elem

The MaterialX element to convert.

Returns

The resulting Protobuf MaterialXElement message.

                                                                         {
    MaterialXElement pb_elem;
    
    pb_elem.set_name(mx_elem->getName());
    pb_elem.set_type(mx_elem->getCategory());
    
    // Copy all attributes preserving order
    for (const std::string& name : mx_elem->getAttributeNames()) {
        Attribute* attr = pb_elem.add_attributes();

    }
    
    // Recursively convert children
    for (mx::ElementPtr child : mx_elem->getChildren()) {
