Detailed Description

template<typename FieldType>
class ignition::msgs::PointCloudPackedIterator< FieldType >

Class that can iterate over a PointCloudPacked message.

E.g, you create your message and reserve space for data as follows:

ignition::msgs::PointCloudPacked pcMsg;
ignition::msgs::InitPointCloudPacked(pcMsg, "my_new_frame", false,
    {{"a", PointCloudPacked::Field::FLOAT32}});
pcMsg.mutable_data()->resize(numPts * pcMsg.point_step());

For iterating over "a", you do :

ignition::msgs::PointCloudPackedIterator<float> iterA(pcMsg, "a");

And then access it through iterA[0] or *iterA.

For iterating over RGBA, you can access each element as uint8_t:

ignition::msgs::PointCloudPackedIterator<uint8_t> iterR(pcMsg, "r");
ignition::msgs::PointCloudPackedIterator<uint8_t> iterG(pcMsg, "g");
ignition::msgs::PointCloudPackedIterator<uint8_t> iterB(pcMsg, "b");
ignition::msgs::PointCloudPackedIterator<uint8_t> iterA(pcMsg, "a");
