LEngine: Forward Rendering Engine DirectX11

tl;dr Watch 1 minute reel!

LEngine is a based on PBR and IBL created in DirectX11 using DirectXTK (newer version of deprecated D3DX). Allows to generate materails through UE4-like system using only visual tools. Managing scene using only visual tools. Full postprocess stack with antialiasing options.

Gallery:

PBR IBL - metallic/roughness comparision

Multiple point light - changing position

Multiple point light - changing color

Materials created using Materials Editor system

Main Features:

• Physically Based Rendering pipeline (metallic workflow)
• Image Based diffuse/specular Lighting (Skybox IBL)
• Multiple directional lights; Multiple editable point lights
• Full postprocess stack: SSAO, LUT, Bloom, Chromatic Aberration, Grain
• Antialiasing: FXAA, SSAA
• Material system - sharing material between objects to reduce rendering costs
• Generating materials through UE4-like editor
• Managing scene: adding new models, changing transforms, moving on scene, adding point lights
• Raypicking OBB
• Importing .obj/.fbx files and storing them in binary format for further usage

• HybridRenderingEngine - my personal source of motivation and mine of great references and ideas
• OBB thread - helpful thread for understanding OBB (in that case, transforming AABB ray and origin to OBB space to perform raypicking)
• FXAA implementation - blogpost explaining simple FXAA implementation without using original NVidia FXAA white paper
• ogldev OpenGL Tutorials - nice blog, mostly useful for simple lights implementations
• MJP explaining MSAA - very theoritical discussion about MSAA including signal processing. Very nice to understand how clever it is (check his other blogpost, he's great!)
• TheEvilBanana Github - some version of lighting were based on that. It's good and easy to implement
