Anti-aliased Alpha Test: The Esoteric Alpha To Coverage
Aliasing is the bane of VR. We have several tools we use to try to remove, or at least reduce aliasing in real time graphics today. Tools like super sampling, temporal anti-aliasing (TAA), and multi sample anti-aliasing (MSAA). They all have their pros and cons, but there’s one tool I don’t feel like gets the use and respect it deserves. That tool is a feature of MSAA, Alpha to Coverage. This arti

The blog at the bottom of the sea
In this post I’ll be showing two different ways to scale points along a specific direction (a vector). There isn’t anything novel here, but it gives an example of the type of math encountered in game development, and how you might approach a solution. The first method involves matrices, and the second involves vector projections. … Continue reading → The C++ code that implements this blog post and

Unity でレイマーチングするシェーダを簡単に作成できるツールを作ってみた - 凹みTips
はじめに レイマーチングとはポリゴンではなく、距離関数（distance function）と呼ばれる数式を元にオブジェクトをレンダリングする方法です。ポリゴンを使わないのでモーフィングや複雑な図形もシンプルな数式で記述することが可能で、GPU のコストが高いという欠点もありますが、面白い見た目を簡単に作り出すことが出来ます。 例えばこれらはキューブのポリゴン（12 ポリゴン）を変形させたものです。 Unity で Command Buffer を使って Raymarching をしてみた - 凹みTips Unity でオブジェクトスペースのレイマーチをやってみた - 凹みTips 最近のエントリもレイマーチングの内容を中心に書いてきました。というのもレイマーチングを積極的に使ったゲームを作りたいなー、と思っているからです。しかしながら、オブジェクトの形状ごとにシェーダを作成しなければな

SIGGRAPH 2016 Course: Physically Based Shading in Theory and Practice
© Disney/Pixar 2016. Course Description Physically based shading has transformed the way we approach production rendering and simplified the lives of artists in the process. By adhering to physically based, energy-conserving models, one can easily create realistic materials that maintain their properties under a variety of lighting conditions. In contrast, traditional ad hoc models have required e
Physics and Math of Shading | SIGGRAPH Courses
Physically based shading models are increasingly important in both film and game production. In this talk, Naty Hoffman (2K Games) provides an introduction to the topic, describing the underlying physics and showing how it relates to the mathematical models used for shading. This talk is an excerpt from the Physically Based Shading in Theory and Practice course at SIGGRAPH 2015. PRESENTER Naty H
