+### Торическая земля:
+- **Ландшафт** (max 1.25)
+    - Генерируется по карте высот (позиции вершин, нормали и текстурные координаты) (0.5)
+    - Текстурируется набором тайлов (0.25)
+        - переключение по высоте/нормали либо по карте материалов (+0.25)
+        - detail текстура при приближении (+0.25)
+- **Торический ландшафт** (1)
+    - Карта высот применяется к тору, как к базовой поверхности.
+- **Управляемая 3D модель** (1/1.25)
+    - Перемещается по поверхности торического ландшафта
+    - Ориентирована по карте высот
+    - "Приклеена" к карте высот
+    - Камера крепится к модели
+        - "Пружинная" камера (+0.25)
+- **Источники света** (0.25/1.25)
+    - Фары/источник света, связанный с объектом, без теней (0.25)
+    - Направленный (солнце) + тени
+        - без каскадов (только объекта на ландшафт) (0.5)
+        - с каскадами (тени от ландшафта и объекта с самозатенением) (1)
+
+## Запуск 
+Собираем проект:
+1) Windows `build.bat` 
+2) Linux `build.sh`
+
+Далее запускаем `build/Task-3-3Dscene`
