Standard Geometry Shader Example

================================

![gif](https://i.imgur.com/hGtXkA7.gif)

This is an example that shows how to implement a geometry shader that is

compatible with the standard lighting model in Unity.

Writing geometry shaders is hard

--------------------------------

Implementing a geometry shader in Unity is not easy as it seems because

[surface shaders] don't allow geometry stage customization -- This means that

you have to implement the whole lighting passes by yourself without the help of

surface shaders.

This example shows the minimum implementation of vertex/geometry/fragment

shader set that provides a custom geometry modification along with the standard

lighting features.

[surface shaders]: https://docs.unity3d.com/Manual/SL-SurfaceShaders.html

Limitations

-----------

To make the example as simple as possible, some features are intensionally

omitted from the shader.

- No forward rendering support (!)

- No lightmap support

- No shadowmask support

- No motion vectors support

- No GPU instancing support

- It hasn't been tested with XR.

It's not impossible to add these features to the shader, that might be pretty

troublesome though.
