如何使用卡通着色器将3D模型转换为专利图纸 [英] How to use toon shader to convert 3D models to patent drawings

问题描述

USPTO要求专利图纸必须是黑白线条图像.

USPTO requires patent drawings to be black and white lines images.

我正在使用Blender制作3D模型.起初我得到了这个:

I'm using blender to make 3D models. At first I got this:

问题是没有黑线的灰度级.有一个建议使用卡通着色器的答案. 将3D模型转换为专利图

The problem is it's grayscale with no black lines.There's a answer to suggest using toon shader. Convert 3D models to patent digrams

我在渲染"选项卡中检查了边缘"并将阈值"设置为最大255，我得到了:

I checked "Edge" and set "Threshold" to max 255 in "Render" tab, I got:

它越来越好，但需要绘制更多的边缘.我搜索并找到了> http://www.minimaexpresion.es/?p= 1070& lang = zh_CN ，那么我得到了:

It's getting better but need more edges to be drawn. I searched and found a tutorial http://www.minimaexpresion.es/?p=1070&lang=en , then I got:

这对我来说太复杂了，我不知道如何使用渲染层.所以我尝试了另一个教程 http://download.blender.org/documentation/oldsite/oldsite.blender3d.org/80_Blender%20tutorial%20Toon%20Shading.html ，它说我应该将具有不同颜色的不同材质分配给不同的对象，因此我尝试并获得了这:

It's too complicated for me and I don't know how to use render layers. So I tried another tutorial http://download.blender.org/documentation/oldsite/oldsite.blender3d.org/80_Blender%20tutorial%20Toon%20Shading.html , which says I should assign different materials with different colors to different objects, so I tried and got this:

只剩下一种拍摄方法:渲染图层.有没有简单的方法可以使其工作?我只想要这个并将其转换为带有黑白调色板的索引颜色:

It leaves only one way to give a shot: render layers. Is there any simple methods to make it work? I only want this and convert it to indexed colors with black and white palette:

自由式"只有一种关于线宽的选择:

And the "Freestyle" only has one option about line thickness:

推荐答案

您在第二张图片中很近.不用使用Edge后处理器，而是在渲染"面板中选中标记为自由样式"的框.

You were close in the second image. Instead of using the Edge postprocessor, look in the Render panel check the box labelled "Freestyle".

然后在渲染层"面板中，将为Freestyle提供一列可配置的选项，包括所需线条的粗细和渲染边缘所需的最小角度.

Then in the Render Layers panel there will be a list of configurable options for Freestyle, including how thick you want the lines and the minimum angle required to render an edge.

最好的结果是，如果您使用的大多数无阴影材料具有简单的纹理(纯色).

The best results are if you use mostly shadeless materials with simple textures (just solid colour).
