========================================================
Projekt: gamematrix (C++ Library)
Rolle: Projektleiter
Datei: requirements.txt
Datum: 10.11.2025
Team: ShehiBr (fuh wit yuh buh)
========================================================
# ----------------------------
# 1. Projektziel
# ----------------------------
Beschreiben Sie hier kurz das Ziel des Projekts:
Ziel: Die Bibliothek gamematrix um grundlegende 3D-Transformationsfunktionen zu erweitern,
die später über pybind11 in Python eingebunden werden können.
# ----------------------------
# 2. Funktionale Anforderungen
# ----------------------------
Listen Sie alle Funktionen auf, die die Bibliothek bereitstellen soll.
Tragen Sie ein: Funktion, Eingabe, Ausgabe, kurze Beschreibung
| Funktion | Eingabe | Ausgabe | Kurzbeschreibung |
|---------------|------------------------------------|-----------------------|----------------------------------------|
| matmul | 4x4 Matrix A, 4x4 Matrix B | 4x4 Matrix | Multipliziert 2 Matrizen |
| translate | 3D Vektor | 4x4 Matrix | Liefert eine Übersetzungs Matrix |
| rot3D | Winkel in °, Rotationsachse (x/y/z)| 4x4 Matrix | Liefert eine Rotationsmatrix |
| identity (optional)| --- | 4x4 Matrix | Liefert eine Einheitsmatrix |
| _____________ | __________________________________ | ____________________ | ______________________________ |
| _____________ | __________________________________ | ____________________ | ______________________________ |
# ----------------------------
# 3. Nicht-funktionale Anforderungen
# ----------------------------
(z. B. Performance, Lesbarkeit, Wartbarkeit, Python-Kompatibilität via pybind11)
- ____________________________________________________________
- ____________________________________________________________
- ____________________________________________________________
# ----------------------------
# 4. Annahmen / Einschränkungen
# ----------------------------
(z. B. alle Matrizen sind 4x4, Winkel in Grad, nur double)
- Alle Matrizen sind 4x4
- Winkel werden in Grad angegeben
- Keine Skalierung, nur Rotation und Translation
# ----------------------------
# 5. Abnahmekriterien
# ----------------------------
Wie soll geprüft werden, dass die Anforderungen erfüllt sind?
(z. B. Unit-Tests, Beispielrotationen, Matrizenmultiplikation)
- Alle Matrixfunktionen liefern korrekte Ergebnisse bei Testeingaben
- Vergleich mit bekannten Referenzwerten (Rotation 90° um x-Achse, etc.)
- Kompilierbarkeit der Bibliothek und Integration in das Spielprojekt
========================================================
Hinweis:
- Diese Datei wird vom Projektleiter erstellt und gepflegt.
- Jede Phase des Projekts soll hier dokumentiert werden.

Projekt: gamematrix (C++ Library)
Rolle: Architekt
Datei: design.txt
Datum: ____________________
Team: ____________________
========================================================
# ----------------------------
# 1. Projektstruktur / Namespace
# ----------------------------
Namespace: _______________________________________________
Ziel: Saubere Trennung der Bibliothek, Vermeidung von Namenskonflikten.
Beispiel:
namespace Matrix3D {
// Funktionen, ggf Klasse(n)
}
# ----------------------------
# 2. Datenstrukturen / Klassen
# ----------------------------
Listen Sie die Klassen oder Structs auf, die verwendet werden:
| Name | Typ | Beschreibung |
|--------|------------------------------------------|--------------|
| Vec3 | struct Vec3 | 3D-Vektor (x, y, z) |
| Mat4 | std::array<std::array<double,4>,4> | 4x4-Matrix (homogen) |
| ______ | ________ | ___________________ |
| ______ | ________ | ___________________ |
# ----------------------------
# 3. Operatoren / Templates
# ----------------------------
Welche Operatoren oder Templates sollen definiert werden?
- Templates für unterschiedliche Datentypen? ☐ Ja ☐ Nein
- Operatoren:
- Mat4 * Mat4
- Mat4 * Vec3
# ----------------------------
# 4. Funktionen / Schnittstellen
# ----------------------------
Liste der Funktionen mit Eingabe/Ausgabe und kurzer Beschreibung:
| Funktion | Eingabe | Ausgabe | Kurzbeschreibung |
|---------------|------------------------------------|-----------------------|----------------------------------------|
| matmul | Mat4 A, Mat4 B | Mat4 | Matrixmultiplikation 4x4 |
| translate | Vec3 pos | Mat4 | Verschiebungstransformation |
| rot3D | double angle_deg, char axis | Mat4 | Rotation um Achse x/y/z |
| identity (optional)| --- | Mat4 | Identitätsmatrix |
| _____________ | __________________________________ | ____________________ | ______________________________ |
# ----------------------------
# 5. Designentscheidungen / Hinweise
# ----------------------------
- Rückgabe der Matrizen per Wert oder Referenz? ___________
- Verwendung von std::array oder std::vector? ___________
- Homogene Koordinaten für Translation / Rotation (4x4)? ☐ Ja ☐ Nein
- Weitere Designüberlegungen: ___________________________
# ----------------------------
# 6. Deliverables / Milestones
# ----------------------------
- design.txt fertig und im Branch architect committed
- Übergabe an Entwickler für Implementierung
========================================================
Hinweis:
- Dieses Dokument dient als Grundlage für die Implementierung.
- Alle Designentscheidungen sollen klar nachvollziehbar sein.
========================================================
