+# 📜 План разработки проекта DOOM 3D (Full 3D WebGL)
+
+**Цель:** Создать полноценный браузерный 3D ретро-шутер в стиле DOOM / Quake на базе **Three.js** (с поддержкой полной трехмерности: многоуровневые карты, перепады высот, лестницы, прыжки, объемные комнаты, освещение и физика коллизий) с аутентичным 2D ретро-HUD.
+
+Доступ по URL: [ai.qpid.pro/doom/](https://ai.qpid.pro/doom/)
+
+---
+
+## 🛠️ Стек технологий
+- **3D Графика & Рендеринг:** Three.js (WebGL / WebGPU) — полноценный 3D пайплайн, шейдеры, динамический свет, тени, партиклы.
+- **Физика и Коллизии:** Octree / Capsule Collider (быстрые коллизии для FPS со сложной геометрией, ступенями, склонами и прыжками) или Rapier3D.
+- **2D HUD / UI:** 2D Canvas / DOM Overlay в аутентичном стиле Doom (панель состояния, анимированное лицо Doomguy, прицел, всплывающие сообщения).
+- **Звук:** Web Audio API (пространственный 3D позиционный звук, ретро-SFX, саундтрек).
+
+---
+
+## 🗺️ Этапы разработки (Roadmap)
+
+### 🔹 Этап 1: 3D Движок и Базовая физика перемещения
+- [ ] Инициализация Three.js сцены, камеры от первого лица (FPS Camera) и рендерера с поддержкой адаптивного разрешения и пикселизации (ретро-эффект).
+- [ ] Захват курсора (Pointer Lock API) и плавный обзор мышью с настраиваемой чувствительностью.
+- [ ] Физический контроллер игрока (FPS Controller):
+  - Перемещение WASD (ходьба, бег с зажатым Shift)
+  - Прыжки, гравитация, падение
+  - Подъем по ступеням и пандусам (step-climbing)
+  - Collision Detection на базе Octree / Capsule против сложной 3D геометрии.
+- [ ] Мобильное управление: виртуальные стики перемещения и обзора + кнопки стрельбы и прыжка.
+
+---
+
+### 🔹 Этап 2: 3D Уровни и Геометрия (Многоэтажность и Архитектура)
+- [ ] Модульный 3D генератор / загрузчик уровней:
+  - Многоуровневые здания, мосты, тоннели, шахты лифтов, балконы и открытые арены.
+  - Поддержка форматов GLTF / OBJ / кастомных воксельных и блочных карт.
+- [ ] Освещение и атмосфера:
+  - Динамические точечные источники света (факелы, мигающие лампы, лава).
+  - Ambient Occlusion, туман (Fog) и затемнение глубины.
+- [ ] Интерактивные 3D объекты:
+  - Раздвижные и подъемные двери с коллизиями.
+  - Настенные переключатели и рубильники.
+  - Платформы и движущиеся лифты.
+
+---
+
+### 🔹 Этап 3: Оружие от 1-го лица и Боевая система
+- [ ] Рендеринг оружия в руках (3D модели / анимированные спрайты с эффектом присутствия):
+  - Кулак / Бензопила
+  - Пистолет (Pistol)
+  - Дробовик (Shotgun / Super Shotgun)
+  - Скорострельный пулемет (Chaingun)
+  - Ракетница (Rocket Launcher)
+  - Плазменная пушка (Plasma Gun / BFG 9000).
+- [ ] Визуальные и физические эффекты стрельбы:
+  - Отдача камеры, покачивание оружия при ходьбе (Weapon Bobbing).
+  - Вспышки дула (Muzzle Flash) с динамическим освещением комнат.
+  - Hitscan лучи с трассерами и искрами/следами от пуль на стенах (Bullet Decals).
+  - Физические 3D снаряды (ракеты, плазменные шары) с частицами дыма и взрывами с радиусом поражения.
+
+---
+
+### 🔹 Этап 4: 3D Враги и ИИ (AI)
+- [ ] Модели / 3D-биллборды классических монстров (Зомби-стрелки, Импы, Демоны, Какодемоны).
+- [ ] Пространственный 3D ИИ с навигацией (Raycast Line of Sight, NavMesh / 3D Waypoints):
+  - Поиск пути с учетом высот и лестниц.
+  - Состояния: Патруль $\rightarrow$ Обнаружение $\rightarrow$ Преследование $\rightarrow$ Атака (дальняя/ближняя) $\rightarrow$ Уклонение $\rightarrow$ Смерть.
+- [ ] 3D Ragdoll / физика отлетающих частиц и анимации гибели монстров.
+
+---
+
+### 🔹 Этап 5: Предметы, Лут и Интерактивность
+- [ ] 3D вращающиеся предметы с мягким свечением:
+  - Аптечки и стимуляторы (Health).
+  - Броня и сферы бессмертия (Armor / Soulsphere).
+  - Коробки с патронами, гильзами и батареями.
+  - Цветные ключ-карты доступа (Red, Blue, Yellow).
+- [ ] Взрывающиеся токсичные бочки (Explosive Barrels) с цепной детонацией.
+
+---
+
+### 🔹 Этап 6: Аутентичный HUD и Интерфейс
+- [ ] Классическая статус-панель в стиле DOOM:
+  - Значения здоровья (HEALTH), брони (ARMOR), патронов (AMMO).
+  - Анимированный аватар Doomguy (эмоции, ранения, оскал при стрельбе).
+  - Индикаторы собранных ключей доступа.
+- [ ] Прицел, всплывающие уведомления о подборе предметов («Picked up a shotgun!») и экран получения урона (красная вспышка).
+- [ ] Экран паузы, меню настроек (FOV, чувствительность, звук, ретро-фильтры).
+
+---
+
+### 🔹 Этап 7: Пространственный Звук и Саундтрек
+- [ ] Web Audio 3D Positional Audio (звук шагов и рычания монстров позиционируется в 3D пространстве).
+- [ ] Звуки выстрелов, перезарядки, взрывов, открывания тяжелых железных дверей.
+- [ ] Динамичный рок / метал саундтрек.
+
+---
+
+### 🔹 Этап 8: Оптимизация, Полировка и Деплой
+- [ ] Стабильные 60+ FPS (Frustum Culling, Instanced Meshes для повторяющихся элементов).
+- [ ] Шейдер пикселизации / CRT-монитора (опциональный ретро-фильтр).
+- [ ] Проверка и тестирование по адресу `https://ai.qpid.pro/doom/`.
