Adeon18 / LRNEngine

A DirextX11 Graphics Engine that I wrote in order to learn Computer Graphics as part of my Dragons Lake Render Internship

LRNEngine

Description

This is my LRNEngine(LeaRNEngine) that I created in order to learn Compute Graphics and Rendering techniques as a part of my Dragons Lake Render Internship. The engine uses the DirectX11 graphics API.

Requirements

Everything already comes with the engine.

• DirectX11
• assimp
• DirectXTex
• DirectXMath
• spdlog
• imgui

Instalation

Download Repo with all the submodules.

git clone https://github.com/Adeon18/LRNEngine.git --recurse-submodules

You can manually connect assimp to be built with the engine, or(recommended) install assimp via vcpkg.

And you're done!

Functionality

The engine implements the following rendering techniques:

• Camera, use LMB to rotate it and WASD, Space Left Ctrl to move
• Object dragging - RMB on model to drag it along the plane, parallel to camera
• Instanced Rendering
• Tesselation
• Model loading via assimp
• Debug normal and vireframe visualization via Geometry Shader
• Directional Lights, Point Lights
• Flashlight - press F to attach/deattach
• HDR and Aces Tonemapping
• PBR and IBL(Cubemaps are precomputed, to compute them yourself enable BAKE_CUBEMAPS in include/config.hpp
• NVidia FXAA 3.11
• Deferred Rendering
• Physically Based Bloom
• Decals that attach to models, press G to cast a decal at mouse pointer
• Model Spawn, press N to spawn a model in front of camera
• CPU particles, press H to spawn a smoke emitter that can be dragged with a mouse
• Model Destruction with GPU particles with lighting and screen space collision, press Del to destroy a model
• Imgui menu that can help dynamically configure a lot of the graphics and logic
• Logging with the help of a spdlog library
