Houdini将几何体转为线的新方法Creative ways to turn geo to lines in Houdini

In this tutorial will be covering how to turn your geometry into lines. Then we will study a couple of different ways that you can make this lines become more interesting, change the form and shape that they have.

Good take aways from this tutorial are:
– Using the Curve tool. This is a great way to animate curves covering your geometry in multiple different ways.
– Applying and controlling the curve tool on high density meshes.
– Using the scatter sop and how to randomize the position of the points as it covers the geometry.
– Connect adjacent pieces : A very powerful tool for connecting the points through lines. Remember to change it to connect adjacent points.
– Use a Vop to control the color of the geometry by applying a noise. Plug the P to the Noise and the noise to the Cd.
– Then we isolat the red channel by applying a float to vector.
– Group expression for isolating the red only.
– Using a delete sop and making its points deleted based on the group we created, therefore deleting the reds or only the blacks.
– Then we use a poly wire and turn this into vdbs.
– We use the vdb – vdb smooth sdf and the Vdb convert to turn it back into polygons.

在本教程中,将介绍如何将几何图形变成直线。然后,我们将研究几种不同的方法,您可以使这些线条变得更有趣,更改其形状和形状。

本教程的主要收获是:
-使用曲线工具。这是一种以多种不同方式对覆盖几何图形的曲线进行动画处理的好方法。
-在高密度网格上应用和控制曲线工具。
-使用散点图,以及在覆盖几何图形时如何随机化点的位置。
-连接相邻的零件:一个非常强大的工具,用于通过线连接点。记住要更改它以连接相邻点。
-使用Vop通过施加噪声来控制几何图形的颜色。将P插入噪音,将噪音插入Cd。
-然后我们通过对向量应用浮点数来隔离红色通道。
-仅用于隔离红色的组表达式。
-使用删除工具,并根据我们创建的组将其点删除,因此删除红色或仅删除黑色。
-然后,我们使用多股线将其转换为vdbs。
-我们使用vdb-vdb smooth sdf和Vdb转换将其转换回多边形。
