Rendering Case Study & Theory

The term is bandied about a lot, often generating confusion as to what exactly it means. The short answer is:

We cover the basics of art content creation, some of the reasoning behind various PBR standards (without getting too technical), and squash some common misconceptions.

I love physically-based rendering, and one of the most important aspects is making sure all your lighting is energy-conserving.

Recently at work I was chatting with a colleague, and the topic of energy conservation for specular reflections came up.

This tutorial discusses the GGX Shading Model which more closely
mimics the look of real reflections on rough surfaces.

Optimizing Mobile Gaming Graphics

Modern graphics hardware requires a high a mount of memory bandwidth as part of rendering operations.

This article contains information about performance optimization of Unity3D games for android.

Optimize, optimize, optimize! There are so many valuable tips and know-how on how to optimize your project in Unity.

One of the fundamental problems in computer graphics is
generating accurate soft shadows from area light sources.

SIGGRAPH 2013

This blog demonstrates an effective and low cost technique to implement reflections when developing games for mobile devices.

Some time ago I did an investigation on if/how Unity can be used as a FX Composer replacement, using the free version as a test.

Clouds are lovely and fluffy and rather difficult to make.

I didn’t really plan to write this post as I’m quite busy preparing for Siggraph and enjoying awesome Montreal summer, but after 3 similar discussion with friends developers I realized that the sim…

Hair rendering technique using polygonal a hair model

The shading performance of modern GPUs, coupled with advances in 3D scanning technology, research in rendering of subsurface scattering effects…

A little while ago I was doing some research into the state-of-the-art for approximating subsurface scattering effects in real-time (mainly for skin rendering)…

Hi everybody, my name is Adam Homoki, live in Budapest, Hungary. After high school, I became a Cad-Cam technician and started working as a draftsman. It didn’t last very long…

Triplanar mapping is a great solution for dealing with texturing on complex geometry that is difficult or impossible to use traditional UVs for with out obvious stretching and/or texture seams.

To review: procedural UVs are amazing and you should consider using them in your games. Now, the old triplanar shader I posted was grea…

In this 2013 GDC session, thatgamecompany’s John Edwards covers all the technical details of the final sand implementation in Journey…

I wanted to go over how I set up different shaders in Redshift, however due to the vast quantity of shaders I used, I thought I would take a few of my main ones- for me these are the cloth texture …

Create outline shaders for Unity that have a stable screen-space width, specified in pixels, regardless of distance from the camera.

Emma Koch discussed her career in 3D and shared her approach to sketching and watercolor effects in her amazing fan arts.

In this article, we will try to explore an anti-aliasing method that works well with deferred shading called temporal anti-aliasing.

So this is going to be part 1 of a two parter that will cover how I created my Slope Aware Rainy Surface Material Function in UE4.
