PRPG

In progress

PRPG (Procedural RPG) is a small C++ project demonstrating procedural generation, rendering, and lightweight LLM integration for in-game behaviors. It's intended as a prototype and research playground for procedural world generation, NPC behaviors, and integration with local model runtimes.

What it is

PRPG is a prototype application that generates procedural roads, terrain and simple city elements, renders them with OpenGL, and experiments with local LLM integration (via `llama`/`ggml`) for NPC/dialogue behaviors.

Features

Procedural road / terrain generation utilities
Deferred OpenGL renderer and skybox
Basic entity system including `player` and `npc` entities
Asset loaders for images, glTF models and simple shaders
Optional local model support using `llama` / `ggml` (model files included under `models/`)

Planned

Improved building generation (procedural placement of building elements like windows, corners, and higher-quality models)
Textured roads and terrains
NPC animations, movements, and richer dialogues
Improved NPC AI and dialogue pipelines
More procedural city elements (traffic simulation)
Save/load functionality for world state and NPC interactions
Performance optimizations and better resource management

Technologies

C++17
CMake (build system)
vcpkg (dependency management)
OpenGL + glad + glm (rendering)
SDL2 + SDL2_ttf (windowing/input and fonts)
nlohmann_json (config / serialization)
llama / ggml / gguf (local model runtimes - optional)
