Project : step 2
Culture boxes and nutrients

Disclaimer: the automatically generated English translation is provided only for convenience and it may contain wording flaws. The original French document must be taken as reference!

Goal: To implement the environment in which our future bacteria will evolve. This will essentially involve culture boxes in which nutrients will grow.

Required concepts: classes, constructors/destructors, operator overloading, inheritance

These concepts are explained in lessons 16, 17, 18 & 19

Required files : partie2.zip

Setup

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 :

You will work on this step in the directory partie2/

As in the previous step, method prototypes and attribute declarations will be located in a file with the .hpp extension, while their definitions will be located in a file with the .cpp extension.

The project description is designed so that your project can compile with the file CmakeLists.txt provided in the folder src/partie2. To ensure that your classes are compatible with the test files provided, you must give your files the same name as the classes they contain. For example, the Nutrient class will be coded in the Nutrient.[hpp][cpp] files.

You must proceed in this manner throughout the project.

(If you do not choose this option, you will need to adapt the test files provided yourself).

General description of the classes to be produced

At this stage, we will begin by modelling the environment in which our future microorganisms will develop. We could simply model a single culture dish, but we will instead adopt a more general approach from the outset, enabling us to conduct several experiments simultaneously, using different culture dishes.

We will therefore start by modelling :

  1. the concept of a culture dish. This is the environment in which the microorganisms will evolve. You will grow nutrients generated at random locations in it;
  2. the laboratory (very basic). For now, this class will simply model the support on which the dishes are placed.

At this stage, you will begin to use your first graphical applications. A class Application.[hpp][cpp] is provided; it will serve as the basis for all your graphical simulation tests.

To summarise, here is the architecture you should have achieved at the end of this stage :

Modele

Let us now proceed to the beginning of the coding. In your programme, you will ensure that your classes are properly encapsulated, in particular by not giving public or protected access to your attributes. You will also systematically provide destructors.

The descriptions suggested below are minimal. This is a first draft that we will refine as the project progresses. You are also free to add any additional methods and attributes that you deem necessary.

Modules to be programmed

The parts (modules) to be implemented to complete this stage are as follows :

The various parts that will be proposed to you throughout the project are not generally all of the same difficulty or length. Familiarise yourself with each of them, at least in broad terms, before you begin programming this stage.

This stage does not present any major difficulties from a programming point of view. However, it will require you to make an effort to understand how the different "pieces of the puzzle" you need to complete fit together and to grasp the usefulness of the tools provided.

At the end of this stage, you will have a simulation environment where you can place nutrients in random locations in several culture boxes and watch them grow automatically :

← Manual addition of nutrient sources (using a key),
nutrient growth based on temperature
and management of multiple boxes, only one of which is visible at a time.
