# Programming tasks for ECG

This repository includes my solutions to the tasks
for the module [*Einführung in die Computergraphik* (Introduction to computer graphics)](https://tu-dresden.de/ing/informatik/smt/cgv/studium/lehrveranstaltungen/ss2023/ecg)
in the summer semester 2023 at the [TU Dresden](https://tu-dresden.de/).

Each exercise includes a separate `readme.txt`
that describes things specific to how I implemented the task.
However, those documents are in German, which is a requirement.

## Usage

### Build

To build a specific exercise,
you can use [Nix](https://nixos.org/) with flake support:

```bash
nix build -L .#u01
```

You can also manually invoke CMake.
This requires you to have all dependencies installed.
Because this is not my preferred way, there is no canonical list of dependencies,
but you can find them in `flake.nix`.

### Development

You can use `nix develop` or [`direnv`](https://direnv.net/).

To create a `compile_commands.json` for `ccls` (or similar),
create a `build` directory inside the exercise directory,
and from that, execute:

```bash
cmake .. -DCMAKE_BUILD_TYPE=Debug -DCMAKE_EXPORT_COMPILE_COMMANDS=YES
ln -sf build/compile_commands.json ..
```

## Licence

Depending on the file,
[GPL-3.0-or-later](https://spdx.org/licenses/GPL-3.0-or-later.html)
or [LGPL-3.0-or-later](https://spdx.org/licenses/LGPL-3.0-or-later.html)
or “Copyright (C) CGV TU Dresden - All Rights Reserved”.

The published version only includes files under free software licences.
Sadly, that makes them very incomplete,
because most implementations done by me are in files from the template,
which makes my additions a derivative work.

All files not marked differently are released under GPL-3.0-or-later.
