CS2 Parser

A tool for parsing and visualizing Counter-Strike 2 physics files (.vmdl).

Overview

This project provides a library for parsing Counter-Strike 2 physics files and a 3D visualization tool to render the extracted geometry. It allows users to extract collision meshes from CS2 maps and visualize them in a 3D environment.

Project Structure

Core Library (/core)

The core library contains the parser implementation that can load and process CS2 physics files:

• cs2/parser.h: Defines the main classes for parsing CS2 physics files
  • Vec3: 3D vector representation
  • Triangle: Triangle mesh primitive
  • HullFile: Represents a physics hull with triangles
  • PhysicsFile: Main class for loading and processing physics files

Visualization Tool (/test)

The visualization tool uses DirectX 11 to render the extracted triangles:

• renderer.h: Defines the 3D rendering system
  • Camera: First-person camera for navigating the 3D scene
  • Renderer: DirectX 11 renderer implementation
  • Application: Windows application wrapper

Usage

Extracting Physics Data

cs2::PhysicsFile physics;
physics.load("path/to/world_physics.vmdl", "working/directory");
physics.displayStats();
physics.writeTriangles("output.tri");

Visualizing Extracted Data

Run the test application which loads the extracted triangle data and displays it in a 3D environment:

test.exe

Use WASD keys to move around, mouse to look, and mouse buttons to interact with the 3D view.

Building

The project requires:

• C++17 compatible compiler
• DirectX 11 SDK
• Windows OS
