iiinova — where your digital self keeps evolving

Started working on a Vulkan renderer last November but I didn't have much time to work on it due to school. I made good progress lately so I thought I'd share my progress on here since I've been "absent" for a while. I got Sponza running at ~3ms @1080p. 1 Dir Light and IBL, nothing too fancy 😄

Foam has been added and that concludes the programming work for this project, as this is the last week. There is a chance that I can take this project over into the next one, where together with a bunch of other Programmers we will develop a specific genre game engine. Looking forward to it 😁

A small update on my Water Rendering journey. I've been busy with shading and researching how I can go from Oceans to Rivers with the integration of flow maps. I don't think I will have enough time to move to Rivers due to time constraints for the project, so I will stick to Oceans for now :P

I'm a bit late, but happy new year everyone! To celebrate another full rotation around the sun, enjoy this meme:

I've been silent for a while, mainly because I didn't have anything interesting to show. I was busy the last couple of days implementing the Tessendorf Model for Ocean Rendering. Massive thanks to @acerola.gg for his videos which helped me a lot! Here's a video of my implementation:

Engine update time! #graphics #vulkan - Implemented uniform buffer objects - Learned about descriptor sets, layouts and pools - Textured quad - Name still hasn't changed due to lack of a better name🫠

A bit of an update on my Vulkan Engine: - I named it "Molten" (turns out there is a library already called moltenvk 😡) - Made some abstractions the other day so I don't stare at 1k lines of code in one file - Got Vertex Buffers up and running today - The repo is public. Feel free to give feedback!

Turns out that 2 major events happened today... First, Trump wins the election unexpectedly, and then the more important one is that I finally managed to get a triangle on screen in my first Vulkan project. Only took ~900 lines of code 😅

"And so... it begins..." - some guy in a movie, probably First time trying Vulkan. If you have any tips for a Vulkan noob, lemme know :)

Also, obligatory Lightsaber render:

Finally managed to get IBL implemented. Granted, without the pre-filtering steps. I ran into this issue where the BRDF LUT was creating some artifacts on the Damaged Helmet. I then decided to take a less "correct" approach and not use the pre-filtered BRDF in the Specular calculation. Here it is:

Going into the final week of the first project of Year 2, I thought I should share what I've been working on. I've been making a PBR renderer for the first time, with the target platform being the PS5. Obviously, I am still lacking IBL so that's what I will be working on this week :)

Ever since I was a kid I thought the Knights Templar were cool. A couple of weeks ago I decided I wanted to get more educated on the topic so I ordered a book. Today, it has finally arrived 😄
