Houdini程序化样条线建模教程 Houdini蜂窝蜂巢程序建模教程 Houdini Procedural Spline Modeling

本套CG教程，已翻译成中文，请享用。

Houdini中Vops VEX用于项目教学，讲解Houdini中程序化建模的步骤流程，包括样条线风格建模，制作复杂的自然生物模型，学习矩阵和旋转运算分配方法，高效学习两个不同类型的黄蜂巢的程序模型生成技术。相对于普通模型数据的顶点，边，面（本质上是顶点和索引），还专有法线的记录方属式，vdb更加适用于烟雾和流体这样形状复杂的物体，它的记录方式是把一团物体拆分成很多个小方块的单位，然后对每一个单位记录密度、速度以及还有各种自定义属性值。

FXPHD – HOU120 – Houdini Procedural Spline Modeling. Solid geometry foundations are the key to being an efficient junior artist, a solid mid-level artist, and diving into advanced setups as a senior. A good knowledge and understanding of proceduralism, vector math, rotation, and population, and look development will benefit any Houdini FX TD at any level.

This course will guide you through two procedural generation exercises of wasp nest formations. Starting from a thorough analysis of reference and a set of creative objectives, you will use Houdini’s proceduralism to produce a completely procedural as well as realistic end result.Techniques involved will use both low-level foundations and modern VDB and surfacing methods including: Vops and VEX for vector math. Matrix and rotational operations. Distribution methods. Fracturing and surfacing. Geometry optimization. Efficient copy techniques. Terrain adaptation. Noise algorithms and properties.
