FusionFrame-Engine

Fusion Frame engine is a framework type game engine that focuses on delivering a compact and easy-to-use interface for 3d game development while preserving speed. It also supports different physics algorithms to speed up the game development.

Rendering Abilities

• Deferred rendering(soon to be clustered deferred as well as forward+ as an option)
• Omnidirectional shadows for point lights
• Linear shadows for directional lights
• PBR-IBL shading
• HDRI and cubemap support
• Deferred and forward mesh instancing
• Compute shader based particle emitter
• Skeletal animation support
• Deferred ScreenSpace decals

Also planning to implement a voxel based GI soon.

Physics Abilities and Data Structures

• Oct/Quad tree for general object class
• Half-edge mesh structure
• Easy collision mesh creation from meshes and bounding boxes
• AABB and SAT collisions

Also using half-edge data structure , wrote couple of premature mesh algorithms like subdivision for triangular meshes. Mesh utility algorithms like quickhull to create collision boxes are also in the TO-DO list

Documentation

The overall API is pretty simple and user friendly. I'll try to demonstrate some of the functionality to get you started

• Initializing the window and the resources

const int width = 1000;
const int height = 1000;

FUSIONCORE::Window ApplicationWindow;
ApplicationWindow.InitializeWindow(width, height, 4, 6, false, "FusionFrame Engine");

FUSIONUTIL::InitializeEngineBuffers();
FUSIONUTIL::DefaultShaders Shaders;
FUSIONUTIL::InitializeDefaultShaders(Shaders);

• Importing a HDRI

FUSIONCORE::CubeMap cubemap(*Shaders.CubeMapShader);
FUSIONCORE::ImportCubeMap("Resources/rustig_koppie_puresky_2k.hdr", 1024, cubemap, Shaders);

• Engine supports both deferred and forward rendering so you can use a gbuffer to use deferred rendering.

const FUSIONUTIL::VideoMode mode = FUSIONUTIL::GetVideoMode(FUSIONUTIL::GetPrimaryMonitor());
FUSIONCORE::Gbuffer Gbuffer(mode.width, mode.height);
FUSIONCORE::FrameBuffer ScreenFrameBuffer(mode.width, mode.height);
