VOPs の紹介

このチュートリアルは VOP ネットワークの紹介ですが、単一チュートリアルでカバーするには大きすぎるテーマです。アトリビュート VOP を見ながら、ポイントアトリビュートの作成と操作方法、演算ノード、ノイズやパターンで位置やカラーを操作してローポリゴンの小さな惑星を作成し、ノイズを元にした大陸や海洋の生成、pscale アトリビュートを使ったポイントに配置した形状のスケールの設定方法を説明します。

Houdini Kitchen tutorials are aimed at experienced 3D artists who are new to Houdini, and focus on creating procedural geometry for video games. Each tutorial covers a single node or concept, and will usually finish with a demonstration of how that tool might be used in asset creation. There are easier ways to use Houdini – commonly used nodes can be set up automatically using shelf tools, and useful networks are now embedded in higher level nodes – but I believe that to be able to fully harness the power of Houdini it is important to understand the basics. I have worked as a Technical Artist in the Video Game industry for 15 years, and my credits include Killzone 2 & 3, The Getaway 1 & 2 and Playstation VR Worlds. I have been learning Houdini since 2005, and have been using it in production for the last 5 years. I also have a degree in Archaeology and have completed several 3D projects for the British Museum.

    Great series. No fuzz, clear explanatory language and you always learn a bit more than what the topic of the tut actually is.
    Thanks!

    Hi Susie,
    first of all: this is the best Tutorial Series I've ever worked my way through. Not just "hey, follow my steps" but packed with a lot of fundamentals that I miss elsewhere.

    I have a question regarding the CopyToPoints Node - around min 30-34 (working with Houdini 18.0.597 on Windows 10).
    Taking into account that ^ does prevent the specified Attribute from being copied/applied to the Geometry - how comes that ^pscale does not have any effect on the result?
    Just as expected, if I disable the Bind-Node in the VOP, all Trees have a uniform scale. However, I would expect the same to happen if I remove this attribute from the CopyToPoints by adding ^pscale to the list (which is the default with the newer nodes). Technically speaking, I see the effect in the Geometry Spreadsheet as pscale is not included in the spreadsheet anymore. But why don't I see this effect in the scene view?
    Help ^^

    Thanks a lot :)
