Game Engine Programming 075.1 - Image based lighting

✅ Support Game Engine Series https://patreon.com/gameengineseries or https://ko-fi.com/gameengineseries In the last two episodes we looked at the theory and implementation of environment cube map pre-filtering for image based lighting. We implemented support for pre-filtered environment maps and wrote compute shaders for pre-filtering the diffuse and specular components, except for the BRDF look-up texture. So that's what we start with in this episode. 🟥(Red Episode) The assets I used in this video are available for Patreon and Ko-fi supporters of the channel: https://www.patreon.com/collection/270663 https://ko-fi.com/gameengineseries/shop ✅ Donations: https://www.paypal.com/paypalme/arashkhatami https://ko-fi.com/gameengineseries ✅ Discord https://discord.gg/75ZmXwz ✅ Twitter https://twitter.com/PrimalNippleMan 🐱 Mr. Frummel & Louis' unreal adventures https://instagram.com/mr.frummel 💜 Big thanks to Tribal Elders: Von Bismarck, Lester Lin, Zachary Shrout 💚 Big thanks to Chief patrons: Simon, Eero Laine, deathcat00 🧡 Big thanks to Shaman patrons: Shaun Mitchell, Talis Lincoln, Miime, Timmy Jenkins, David Ducados, Soheb Bhimani, Wladimir Termont Further reading: HLSL Constant Buffer Layout Visualizer: https://maraneshi.github.io/HLSL-ConstantBufferLayoutVisualizer/ Image-based Lighting (IBL) of PBR Materials [Shaders Monthly #11]: https://youtu.be/MkFS6lw6aEs?si=m5OK7V0Q4yVEnXeH Real Shading in Unreal Engine 4: https://cdn2.unrealengine.com/Resources/files/2013SiggraphPresentationsNotes-26915738.pdf Siggraph 2014 : Moving Frostbite to Physically based rendering: https://seblagarde.wordpress.com/wp-content/uploads/2015/07/course_notes_moving_frostbite_to_pbr_v32.pdf IBL in Filament rendering engine: https://google.github.io/filament/Filament.html#lighting/imagebasedlights/processinglightprobes 00:00 - intro by Arash Khatami ------------------------------------------------------------- #PrimalEngine #GameEngineSeries #GameEngineProgramming #TheGameEngineProgrammingSeries
