毛发渲染总结 - 知乎 - 知乎专栏
毛发的渲染技法有很多。 我们主要讨论模型和着色的方案。 一.毛发模型方案. 1.1 Shell Based Fur. 这类毛发可以参考GFur Pro插件。 这类毛发技术使用的是多层渲染。 如下图所示，只要这些面片距离足够的近，我们就有一种是单根头发的错觉。 这类技术的问题是如果我们需要长的毛发，那么我们就需要非常多的截面，性能受到的影响就越大。 当然我们并不是一个面片一个面片进行绘制，密集毛发是通过在单个多边形上绘制多个毛发横截面来实现的。 如果我们以一个球体为 …
Strand based hair rendering实践——总体流程 - 知乎 - 知乎专栏
2021年1月2日 — 渲染. 我们选择的光照模型是Marschner。. 选择的光源衰减算法是套用了DOM方式的Dual Scattering算法。. 为了避免半透明排序的问题，我们的发丝采用不透明渲染。. 这带来的另一个问题是由于发丝非常细，其宽度通常无法占用一个完整像素，所以必须进行抗锯齿处理 ...
[siggraph19]寒霜引擎中strand-based(基于线)的头发渲染 - 知乎
这篇可以说把hair render往前推进了一步，主要亮点： 开始使用线来做头发渲染(strand based)，这个也构成了头发品质飞跃的一个好的基础; 进一步处理头发中multiple scattering的问题; 头发在游戏中渲染的简要历史
Real-Time Hair Rendering with Hair Meshes - ACM Digital Library
Hair meshes are known to be effective for modeling and animating hair in computer graphics. We present how the hair mesh structure can be used for efficiently rendering strand-based hair models on the GPU with on-the-fly geometry generation that provides orders of magnitude reduction in storage and memory bandwidth.
Accelerating Hair Rendering by Learning High-Order Scattered …
A renderer to path trace hair by using learnt approximations of high order radiance. The renderer provides control over it's bias (w.r.t. ground truth path tracing) and the speedup. In essence, more speedup results in more bias and vice versa.
GitHub - CaffeineViking/vkhr: Real-Time Hybrid Hair Rendering …
It's capable of rendering strand-based hair geometry in real-time, even for fully simulated hair styles with over 100,000 strands. Our hybrid rendering pipeline scales in the performance/quality domain by using a rasterizer for closeup shots and a raymarcher for level of detail minification.
How I Color/Render Hair - YouTube
How I Color/Render Hair. Finally making one of the most requested contents over the years: Rendering hair!! My workflow is a bit chaotic; but I try my best to explain the basics and make it...
GaussianHair: Hair Modeling and Rendering with Light-aware …
This paper presents GaussianHair, a novel explicit hair representation. It enables comprehensive modeling of hair geometry and appearance from images, fostering innovative illumination effects and dynamic animation capabilities.
Hair Rendering and Modelling – An Intro | 头发渲染与建模 – 简介
2019年3月31日 — Physically Based Hair Shading in Unreal 官方示例Realistic Character中便用了这个光照模型。 论文最主要的贡献是从微观模型角度对毛发的光照做了分析，并用设备测量了光照的分布，和模拟结果对比证明建模很有效。
Learn How to Render Hair with These Tutorials - Cubebrush
From curly to straight, thick to thin, and long to short, different hair textures, densities, patterns, and lengths require unique approaches to rendering. This helpful tutorial will help you establish the different approaches and tools necessary when producing a …
