Fluxions 5.0 begins
Well, Fluxions 4.0 didn’t exactly work out. I spent the better part of the last few years focusing on learning Metal. I learned a lot and I think that’ll feed into the next version of my hobby rendering engine. This time I’m going to work on embracing ray tracing and both Metal and Direct3D 12.…

LibXOR Colors
The LibXOR colors is a set of sixteen core colors which are designed to be mixed in a 16-bit format for pixel art purposes. They are originally for a work-in-progress graphics library called LibXOR–which has been paused for a little bit of time. Nonetheless, I love these colors and my desire is for them to…

Working with Vulkan
So, work on Fluxions 4.0 has begun. I started out by digging into Kristian Høgsberg Kristensens’ vkCube source code. I think he did a good job laying out all the essential pieces. Vulkan like OpenGL is a C library at heart. Instead of many state calls, you need to fill in data structures with all…

Fluxions Engine 3.0: The History of a Research Graphics Engine
The first graphics engine I wrote was in the late 1990s which I originally named KA3D — short for Kick-Ass 3D. But, I couldn’t commit to this name because it had a slight hint of profanity which I am generally uncomfortable with. So I changed it to Fluxions after the Method of Fluxions which Isaac…

Gamedev This Year
Furtual Rabbit was my first game in a year. It was revealing how out of practice I had gotten. It might be time to start doing more One Hour Game Jams. On the other hand, I got a lot of experience with computer graphics and simulation techniques which was my main focus during the academic…

Conversion between specular exponent, specular roughness, and specular glossiness
[mathjax] Ever need to convert between specular exponent, roughness, and glossiness? for the Blinn-Phong BRDF, these three values represent the same concept. Specular Exponent is the actual value used to compute the BRDF. Let’s call that variable . The roughness and glossiness values are numbers between 0 and 1 and they are additive inverses of…
