Since I posted my Raytraced Audio video back in April, nearly everything has changed:
no more voxels - rays now collide against 3D primitives (meshes, spheres, cubes, etc)
no more basic reverb blending - reverb is now calculated using echograms, materials and energy-based models
basic occlusion and permeation system replaced with energy-based models and air absorptio...

Hi all, I'm working on a lot of different things and thought I'd give an update.
Also, welcome to all the new Patrons! We've had an influx over the past couple weeks as we've had a spike in YouTube views. I hope you all have access to the engine on GitHub, if not please let me know.
A lot of new code is being merged back to the main branch soon

Since audio raytracing is performed against voxels, I need a way to convert the 3D terrain, meshes and shapes in your games to voxels.
I had this working for my Raytraced Audio video:
This worked great, but it was slow. Each frame I was removing all the voxels, then converting each triangle in ...

I've started writing documentation for the engine and it's publicly available at https://publish.obsidian.md/ve. It's a work in progress, I'm working on it every night so check back daily for the latest updates.
My goal is for the engine to be intuitive to use, and provide plenty of examples to go with it. While this engine won't compete with Godot or Unreal, my hope is that it'll help you learn and experiment with O...

Hi all, I've been working on some exciting features and improvements for the next Raytraced Audio demo. Here's a recap of what I've done.
I've been researching how reverb parameters like diffusion/density/decay/etc are influenced by the materials and shape of the environment around you.
I'm now setting each reverb parameter based on:
materials around you
length of returning rays
standard deviation of the leng...

I’ve just recorded the final version of the script, which is my favourite part (to get out of the way) of making videos. I think by now I can say the entire script off by heart!
Thank you to Lachy, Outer Cloud and PyjamSy for teaching me all things audio: how far away to stand from the mic, the best mic settings, how to reduce echo, equalisation, and much more.

Thank you to everyone (Patrons, friends, family) who provided feedback on the the first draft. Here's the second draft, which addresses the feedback listed below.
I would love to hear your feedback on this version as well. It's a constant iterative process!

The initial segment about spatialised audio has been cut down heaps. This is because the video is about raytracing, but the raytracing segment starts at 2:40, which is too far in. In...

Hey everyone, I would love to get your feedback on the first draft of my Raytraced Audio video.
Because my script is constantly changing and the timing of the animations must match my voice, I don't polish the animations until the script is final. This draft has freeze frames, sharp transitions, and poor audio, so I'm not looking for feedback on:
transitions / overall video editing
audio / voiceover quality (emotion in my voice, background noise, echo)

Every year I look back at the things I've done, and it's never enough. There's so much more to learn and accomplish.
Let's look at some stats for 2024.
After 2.9 million views and 57,400 subscribers gained, I'm 85% of the way to my goal of getting a Silver Play Button (100,000 subscribers). I haven't worked on a video in 8 months - I need to get my act together!
Hi-res video and screenshots are available here
Most games use one of two rendering systems:
Forward Rendering - objects are rendered at full quality when they are first rendered
Deferred Rendering - objects are rendered quickly, then expensive effects are applied later on
Full-res images and bonus videos are available here.
Over the past 3 months I have reworked this engine into something that's fun and easy to use. OpenGL can be very tedious and my goal is to help you understand and enjoy using it.
The ultimate test of this engine's production-readiness was if it could power a...

The purpose of networking is to connect players together, then make them forget they live on opposite sides of the world.
I live in Australia, and the majority of Sector's Edge players lived in America and Europe. If I wanted to enjoy playing my own game, it needed to have good networking.
This article covers the main networking issues I faced while making Sector's Edge:
Ping calculation + fluctuation

2024-09-07 09:18:53 +0000 UTC View PostWhen people think of optimisation they usually think about fast 3D rendering, quick loading screens, powerful physics engines and small download sizes.
But one day I was profiling Sector's Edge and found that the user interface took the same amount of time to render as the 3D world. I was shocked - the UI was so simple but so slow!
It turns out that UI is still a form of rendering and requires the same optimisations as 3D rendering. OpenGL makes it easy to apply these optimisation...

The core feature in Sector's Edge is its destruction. When a building is no longer connected to the ground, it should come crashing down.
Buildings could be composed of hundreds of thousands of voxels, so we need an incredibly quick way of checking if a building is floating or not. I call these Floating Voxel Checks (FVC).
I was still in university when I was working on this back in 2020, so I killed 2 birds with 1 stone and did my computer science major project on FVCs.
