Game Design

长文：Fortnite堡垒之夜中的建造系统分析

• http://gamerboom.com/archives/95556

• 因为好奇曾经尝试玩过一周Fortnite，觉得其中建造系统确实给操作带来了另一个维度，但门槛有点高变化缺不多

• 正好读到这篇详细地讨论了这个

The Design is the Implementation

• http://www.gamasutra.com/blogs/DanielShumway/20180814/324413/The_Design_is_the_Implementation.php

• 貌似是Reset Hard这个游戏的开发日志，讨论了设计和实现的关系

• You should avoid thinking about your game's architecture as a completely separate concern from its design

• 里面的引用也很棒

"When you ask a programmer to design the algorithm itself, there are repeated confirmations and adjustments until you reach a satisfactory end result. That takes time and can get you distracted from what you originally wanted to do, so sometimes I design the algorithm myself here when I can, and ask them to implement it using the calculations. We try to convey non ambiguous ideas and make sure that the final implementation is as close as possible to the design of algorithm."

Interior Mapping

• 用raytrace来伪造窗户内部空间。虽然不是新东西了，spider-man一出又带了一波热度

Graphics

PBR missing rim darkening on non metallic rough surfaces

• https://computergraphics.stackexchange.com/questions/8057/pbr-missing-rim-darkening-on-non-metallic-rough-surfaces

• 大致看了下主要是常用的lambertian没有考虑fresnel和multi-scattering

• 用Disney或者Oren-Nayar的话会有一定程度但也不是完全解决

• 顺便强烈推介这个人的blog https://blog.demofox.org/

Why does graphics speak of “dielectrics” rather than insulators?

• https://computergraphics.stackexchange.com/questions/8052/why-does-graphics-speak-of-dielectrics-rather-than-insulators

• 为自己长久以来的疑惑给了个能接受的解答

• 搞Graphics其实不在意导不导电，盐水也导电但不是介电质

• 介电质影响Fresnel effect，也就是影响外观，对Graphics来说外观才是重点

• Stackexchange的Computer Graphics板块也活跃起来了真好

BREAKING DOWN BARRIERS – PART 5: BACK TO THE REAL WORLD

• https://mynameismjp.wordpress.com/2018/09/08/breaking-down-barriers-part-5-back-to-the-real-world/

• 结合前4篇的简化版GPU介绍了真实GPU的处理流程，并从WDDM的诞生和发展来补充说明了与GPU交互部分的变迁
