使用SpeedTree创建高分辨率的自定义树模型

通过Jean-Michel Bihorel的中级教程，了解如何使用SpeedTree和Houdini生成外观复杂的树。从简单的生成规则开始，然后深入到SpeedTree和Houdini中更高级的树生成领域，Jean-Michel教授了生成英雄树资产所需的每个步骤——非常适合在电影中使用。

在整个研讨会中，Jean-Michel分享了如何创建由程序生成器扩展的手绘分支的混合，以及如何使用网格力来获得逼真的结果。他还揭示了如何在Houdini中设置和导出树叶作为点云，以便管理更优化的设置，以及基于太阳方向对树叶几何体的生成和放置进行更好的程序控制。The Gnomon Workshop – Creating High-Resolution Custom Trees Using SpeedTree

对于那些不想将树资源导出到Houdini的人，Jean-Michel还提供了将树导出到其他软件(在这种情况下是Maya)的指导，以及如何让着色器在其他软件包中工作的建议。

在本教程结束时，你应该可以轻松地生成从任何表面生长的各种树木，包括从树木生长各种其他植被。您还将深入了解如何在软件之间导入和导出资产。

虽然这不是一个入门教程，你不需要成为一个SpeedTree的专家。

Discover how to generate complex-looking trees using SpeedTree and Houdini, with this intermediate-level tutorial by Jean-Michel Bihorel. Starting from simple generating rules before deep-diving into more advanced areas of tree generation in SpeedTree and Houdini, Jean-Michel teaches every step needed to generate a hero tree asset — perfect for use in a cinematic.

Throughout the workshop, Jean-Michel shares how to create a mixture of hand-drawn branches extended by procedural generators, as well as how to use the mesh forces for realistic results. He also reveals how to set up and export a leaf as a point cloud in Houdini in order to manage a more optimized setup, as well as great procedural control over the leaf geometry generation and placement based on the direction of the sun.

For those that don’t want to export their tree assets to Houdini, Jean-Michel also provides guidance for exporting your trees into other software — in this case, Maya — along with advice for how to get your shaders working in other software packages.

By the end of this tutorial, you should feel comfortable generating a variety of trees growing from any surface, including growing a variety of other vegetation from trees as well. You will also develop a solid understanding of how to deal with importing and exporting your assets between software.

While this is not an introductory-level tutorial, you are not required to be a SpeedTree expert in order to follow along.
