Unity3D，圆框的边缘，立方体吗? [英] Unity3D, round the edges of a box, cube?

问题描述

在示例中，将立方体的矩形上的边缘圆角的常用方法是什么?

What's the usual way to round the edges on a cube, a rectangular object as in the examples?

理想的结果看起来与这些图像非常相似.

The ideal result would look pretty much exactly like these images.

(自然地，您实际上可以使用具有精心倒圆的边缘和角落的网格，但是要花费很多时间才能做到这一点.)

(Naturally, you could literally use a mesh that has carefully rounded edges and corners, but it takes many tris to achieve that.)

请注意，当然是 NON 着色器方法...

Note, of course for a NON-shader approach...

添加两个小扁平盒，然后在两侧之间简单地进行新的正常中途，即45度:

Add two small flat boxes and simply make that new normal halfway, i.e., 45 degrees, between the two sides:

那会完美地画出来...

That would be drawn perfectly round ...

下面的GDG提供了一篇文章，其中有人断言，即使不使用着色器方法，这的确是最好的方法.

GDG below has provided an article where someone asserts that this is indeed the best way, if not using a shader approach.

我真的很想知道如何使用着色器做到这一点.

I'm really wondering how to do this with a shader though.

注意-有关非着色方法的详细教程，

推荐答案

使用递减阴影，您可以像在

Using deferred shading you may access G-buffer to locate and round edges like it done in this paper. Though it is a post-processing technique so it is able to emulate roundness in a limits of some pixels.
