No idea if any of this mechanical parroting will make any sense or yield fruit,
but I have a little time before heading out for the night.

"Show a code sketch of the decoupling and Suggest tests for each module"


raytracer in POV-Ray, followed by test suggestions for each module.

Code Sketch: Modular Decoupling
1. SceneGraph Module (Neutral Representation)

// scenegraph/Scene.h
#pragma once
#include <vector>
#include <memory>
#include "Object.h"
#include "Camera.h"
#include "Light.h"

class Scene {
public:
    std::vector<std::shared_ptr<Object>> objects;
    std::vector<std::shared_ptr<Light>> lights;
    std::shared_ptr<Camera> camera;

    void AddObject(std::shared_ptr<Object> obj);
    void AddLight(std::shared_ptr<Light> light);
    void SetCamera(std::shared_ptr<Camera> cam);
};


2. Parser Module (No Rendering Dependencies)

// parser/SceneParser.h
#pragma once
#include <string>
#include "../scenegraph/Scene.h"

class SceneParser {
public:
    static std::shared_ptr<Scene> ParseFromFile(const std::string& filename);


3. Adapter Module (SceneGraph → Core Raytracer)

// adapter/SceneAdapter.h
#pragma once
#include "../scenegraph/Scene.h"
#include "../core/RenderScene.h"

class SceneAdapter {
public:
    static std::shared_ptr<RenderScene> ConvertToRenderScene(const
std::shared_ptr<Scene>& scene);
};

4. Raytracer Module (No Parser Dependencies)

// core/RenderScene.h
#pragma once
#include <vector>
#include "RenderableObject.h"
#include "LightSource.h"
#include "Camera.h"

class RenderScene {
public:
    std::vector<RenderableObject> renderables;
    std::vector<LightSource> lights;
    Camera camera;

    void Render();
};

 Suggested Tests for Each Module
🔹 Parser Module


Unit Tests

Parse valid scene file → returns correct SceneGraph structure.
Parse invalid syntax → throws descriptive error.
Parse edge cases (empty file, nested macros, etc.).



Mock Tests

Mock file input and assert SceneGraph output structure.




🔹 SceneGraph Module


Unit Tests

Add/remove objects and lights.
Validate camera assignment.
Ensure deep copies or shared_ptrs behave correctly.



Integration Tests

Construct a Scene manually and verify structure.




🔹 Adapter Module


Unit Tests

Convert SceneGraph with known contents → RenderScene with expected
renderables.
Handle missing camera or lights gracefully.



Mock Tests

Mock SceneGraph and assert correct RenderScene output.




🔹 Raytracer Module


Unit Tests

RenderScene::Render() with minimal scene → produces image buffer.
Test bounding volume hierarchy, intersection logic, shading.



Performance Tests

Render large scenes and measure frame time.
