GFX 1.0.6

GFX Game Engine

Welcome to the GFX Game Engine – an open-source framework designed to make game development simple, powerful, and accessible.

If you have any questions about GFX, join our community on Discord.

Overview

The GFX Game Engine is a lightweight framework for creating 2D and 3D games in C# with .NET 8. It includes modules for rendering, graphics, animation, and audio.

Why Choose GFX?

• Effortless creation of 2D and 3D scenes
• Custom behavior system for defining game logic
• Powerful physics simulation using BulletSharp (a Bullet3 wrapper)
• Support for multiple 3D model formats via Assimp integration
• Rendering powered by OpenGL through OpenTK
• 3D audio support with OpenAL (coming soon)
• Open-source and MIT-licensed for unlimited creative freedom

Core Features

Rendering

GFX utilizes OpenGL 4.5 via OpenTK for high-performance rendering, with full support for custom shaders and materials. Supported 3D file formats include Wavefront (.obj), FBX, Collada, and GLTF. Future roadmap: support for Vulkan and DirectX 12.

• Multiple Lights in 2D & 3D Scenes – Support for multiple light sources in both 2D and 3D environments, with realistic lighting behavior (not just blending).
• Experimental PBR Rendering – Initial integration of Physically Based Rendering (PBR) for primitives.
• Specular Glossiness Shader Optimizations – Performance and visual improvements for specular lighting.
• Frustum Culling for Lights – Efficiently cull light sources outside of the view frustum for better performance.
• Instanced Rendering (2D & 3D) – Enhanced rendering performance for multiple identical objects.
• Support for SSBOs & ArrayBuffers – New support for Shader Storage Buffer Objects (SSBOs) and ArrayBuffers in the rendering pipeline.

Physics

Physics in GFX are powered by BulletSharp, a .NET wrapper for the robust Bullet Physics library. Features include:

• PhysicHandler3D and PhysicHandler2D for seamless simulations.
• New Rigidbodies and Triggers for advanced 3D physics.
• 2D Physics Integration – Fully integrated 2D physics system.

Audio

• 3D Sound via OpenAL – Spatial audio support for more immersive soundscapes. (OpenAL must be installed or the DLL manually included.)

Lighting Management

• Light Manager – New system for managing lights in both 2D and 3D scenes.
• Clustered Frustum Culling (2D & 3D) – Optimized light culling system to improve rendering performance.

Getting Started

Installation Guide for GFX (.NET 8)

1. Install the GFX NuGet Package dotnet add package GFX
