### Separate nodes for better readability
|
||||
|
||||
```c++ {.bad}
|
||||
CalculatorGraphConfig BuildGraph() {
|
||||
Graph graph;
|
||||
|

// Inputs.
|

|
||||
Stream<B> b = node1.Out("OUTPUT").Cast<B>();
|
||||
auto& node2 = graph.AddNode("Calculator2");
|
||||

|
||||
Stream<C> c = node2.Out("OUTPUT").Cast<C>();
|
||||
auto& node3 = graph.AddNode("Calculator3");
|
||||
b.ConnectTo(node3.In("INPUT_B"));
|
||||
c.ConnectTo(node3.In("INPUT_C"));
|
||||
Stream<D> d = node3.Out("OUTPUT").Cast<D>();
|
||||
auto& node4 = graph.AddNode("Calculator4");
|
||||
b.ConnectTo(node4.In("INPUT_B"));
|
||||
c.ConnectTo(node4.In("INPUT_C"));
|
||||
d.ConnectTo(node4.In("INPUT_D"));
|
||||
Stream<E> e = node4.Out("OUTPUT").Cast<E>();
|
||||
// Outputs.
|
||||
b.SetName("b").ConnectTo(graph.Out(0));
|
||||
c.SetName("c").ConnectTo(graph.Out(1));
|
||||
d.SetName("d").ConnectTo(graph.Out(2));
|
||||
e.SetName("e").ConnectTo(graph.Out(3));
|
||||
|
||||
return graph.GetConfig();
|
||||
}
|
||||
```
|
||||
|
||||
In the above code, it can be hard to grasp the idea where each node begins and
|
||||
ends. To improve this and help your code readers, you can simply have blank
|
||||
lines before and after each node:
|
||||
|
||||
```c++ {.good}
|
||||
CalculatorGraphConfig BuildGraph() {
|
||||
Graph graph;
|
||||
|
||||
// Inputs.
|
||||
Stream<A> a = graph.In(0).Cast<A>();
|
||||
|
||||
auto& node1 = graph.AddNode("Calculator1");
|
||||
a.ConnectTo(node1.In("INPUT"));
|
||||
Stream<B> b = node1.Out("OUTPUT").Cast<B>();
|
||||
|
||||
auto& node2 = graph.AddNode("Calculator2");
|
||||
b.ConnectTo(node2.In("INPUT"));
|
||||
Stream<C> c = node2.Out("OUTPUT").Cast<C>();
|
||||
|
||||
auto& node3 = graph.AddNode("Calculator3");
|
||||
b.ConnectTo(node3.In("INPUT_B"));
|
||||
c.ConnectTo(node3.In("INPUT_C"));
|
||||
Stream<D> d = node3.Out("OUTPUT").Cast<D>();
|
||||
|
||||
auto& node4 = graph.AddNode("Calculator4");
|
||||
b.ConnectTo(node4.In("INPUT_B"));
|
||||
c.ConnectTo(node4.In("INPUT_C"));
|
||||
d.ConnectTo(node4.In("INPUT_D"));
|
||||
Stream<E> e = node4.Out("OUTPUT").Cast<E>();
|
||||
|
||||
// Outputs.
|
||||
b.SetName("b").ConnectTo(graph.Out(0));
|
||||
c.SetName("c").ConnectTo(graph.Out(1));
|
||||
d.SetName("d").ConnectTo(graph.Out(2));
|
||||
e.SetName("e").ConnectTo(graph.Out(3));
|
||||
|
||||
return graph.GetConfig();
|
||||
}
|
||||
```
|
||||
|
||||
Also, the above representation matches `CalculatorGraphConfig` proto
|
||||
representation better.
|
||||
|
||||
If you extract nodes into utility functions, they are scoped within functions
|
||||
already and it's clear where they begin and end, so it's completely fine to
|
||||
have:
|
||||
|
||||
```c++ {.good}
|
||||
CalculatorGraphConfig BuildGraph() {
|
||||
Graph graph;
|
||||
|
||||
// Inputs.
|
||||
Stream<A> a = graph.In(0).Cast<A>();
|
||||
|
||||
Stream<B> b = RunCalculator1(a, graph);
|
||||
Stream<C> c = RunCalculator2(b, graph);
|
||||
Stream<D> d = RunCalculator3(b, c, graph);
|
||||
Stream<E> e = RunCalculator4(b, c, d, graph);
|
||||
|
||||
// Outputs.
|
||||
b.SetName("b").ConnectTo(graph.Out(0));

c.SetName("c").ConnectTo(graph.Out(1));

d.SetName("d").ConnectTo(graph.Out(2));
|
||||
e.SetName("e").ConnectTo(graph.Out(3));

// Procrustes solver using the screen runtime landmarks.

// On this iteration, screen landmarks are used instead of unprojected

// metric landmarks as it is not safe to unproject due to the relative
|

// nature of the input screen landmark Z coordinate.
|

//
|

// (3) Use the canonical-to-runtime scale from (2) to unproject the screen
|

// landmarks. The result is referenced as "intermediate landmarks" because
|
||||
// they are the first estimation of the resuling metric landmarks, but are
|
||||
// not quite there yet.
|

//
|
||||
// (4) Estimate a canonical-to-runtime landmark set scale by running the
|
||||
// Procrustes solver using the intermediate runtime landmarks.
|
||||
//
|
||||
// (5) Use the product of the scale factors from (2) and (4) to unproject
|
||||
// the screen landmarks the second time. This is the second and the final
|
||||
// estimation of the metric landmarks.
|
||||
//

// transformation matrix to align the runtime metric face landmarks with
|
||||
// the canonical metric face landmarks.
|

//
|
