One of those classic setups again! This time we’re combining custom point advection with a few nifty techniques in Houdini to analyze how our base geometry is shaped and where its edges are. Also we’ll talk briefly about a basic rendering setup in Octane.

00:00 – Intro
00:23 – Base Setup
01:48 – VDB + Triangular Remeshing
02:55 – Measuring Curvature + Gradient
04:00 – Orthogonal Vectors Using Cross Product
06:36 – Scattering Points Onto Edges
09:32 – Setting Up Advection Solver
12:40 – Points to Lines
13:15 – Width Attribute For Rendering
14:35 – Setting Up Octane Render
17:17 – Infamous Last Words

又是那些经典的设置之一！这次我们将自定义点平流与 Houdini 中的一些漂亮技术相结合，以分析我们的基础几何形状是如何形成的以及它的边缘在哪里。我们还将简要讨论 Octane 中的基本渲染设置。

00:00 – 介绍
00:23 – 基础设置
01:48 – VDB + 三角形网格重新划分
02:55 – 测量曲率 + 梯度
04:00 – 使用叉积的正交向量
06:36 – 将点分散到边缘
09:32 – 设置对流求解器
12:40 – 点到线
13:15 – 渲染的宽度属性
14:35 – 设置 Octane 渲染
17:17 – 臭名昭著的遗言
