Accurately Timing Video Frames: A Guide to 29.97 and 59.94 FPS

Understanding video frame rates can be tricky, especially if you come from a real-time graphics background where everything is measured in milliseconds. Most video formats use a simple frame rate of 30 frames per second (FPS), which translates to 33.3333 milliseconds per frame. However, when it comes to 29.97 and 59.94 FPS video, the timing is a bit more complicated.

Why Tipping Culture in Canada Needs to Go

Tipping culture is a contentious topic across the globe, and Canada is no exception.

Introduction to Shader Programming

Apparently, I said it would happen soon-ish, but totally forgot about mentioning it when the book was out almost an year ago. I guess I was just occupied with other things for the last 10 months.

New HLSL in this chapter ceil(): finds the smallest integer value greater than the input parameter.

05. Let's Add Colors to Objects: Diffuse/Specular Shader

Why do different objects have different colors? It is because they absorb and reflect different spectrums of incoming light. For example, a black surface looks black because it absorbs all the spectrums, and a white surface is white because it reflects everything. Likewise, a red surface reflects red spectrum while absorbing the others.

Future of Intro to Shader Programming Book

I have been posting the English version of my Intro to Shader Programming book in this blog. I intended to publish it some years ago, but I had more important things to occupy myself. I thought it was a bit too late to publish this book, but I got lucky this time.
