Required concepts: classes, constructors/destructors, inheritance, polymorphism

Required files : partie3.zip

Setup

• Setup for Linux/macOS (in French);
• Setup for Windows (in French).

The archive provided for this step contains a new version of the file CmakeLists.txt which allows you to compile the material in this section. It also contains :

• A new version of the file res/app.json containing additional parameters .
• A new version of the file Utility.[hpp][cpp] where a function is added to facilitate the drawing a the bacteria's sinusoidal flagellum.
• Utilities for numerical integration src/Utility/DiffEqSolver.[hpp][cpp].
• Various test files located in the subdirectory src/Tests.
• A new simulation kernel Application.[hpp][cpp] from which all your graphical simulation tests will be derived.
• New resources in the directory res/.

General description of the classes to be created

This important step will allow you to begin modeling an initial type of bacteria, single-flagellated bacteria. You will anticipate the presence of other types of bacteria and propose a generic model of bacteria in general, allowing you to group together all the elements they have in common.

Among the characteristics of bacteria, some may mutate over time. Utility classes will be introduced to manage mutable parameters (whose values change randomly over time).

Finally, you will apply your new knowledge of polymorphism to differentiate between nutrient sources. Nutrient sources may develop spontaneously, without manual intervention.

To summarize, here is the essence of the architecture you should have achieved by the end of this stage:

Let's now begin coding. In your program, be sure to encapsulate your classes properly, in particular by not making your attributes public or protected (unless explicitly stated otherwise in the problem statement). You should also always include destructors.

Modules to be programmed

The components (modules) that need to be implemented to complete this step are as follows:

• Differentiation of nutrient sources
• Mutable parameters
• General bacteria
• Single-flagellated bacteria (uniform linear movement)

At the end of this step, the features needed to simulate the basic movement of single-flagellated bacteria as well as nutrient consumption will be available. Nutrients can be automatically generated
