# 3D Design Guidelines

The 3D Design Guidelines are a resource to help you design and build jaw-dropping 3D experiences. They contain the most helpful tips and tricks we've discovered over the years building and reviewing countless Looking Glass apps.

As "hologram development" is a relatively new field, these guidelines are by no means an exhaustive list, so we expect this document to evolve as we continue to learn.

**NOTE**: this guide is tailored to developing in Unity. That said, all the principles covered in this guide apply in other development contexts, whether or not the implementation details are similar.

## Topics

* [Scene Composition](/keyconcepts/3d-design-guidelines/scene-composition.md): How to compose a scene that takes advantage of the optical properties of the Looking Glass
* [Lighting](/keyconcepts/3d-design-guidelines/lighting.md): How to cleverly light your scene so that it pops into the third dimension
* [Materials and Textures](/keyconcepts/3d-design-guidelines/materials-textures.md): A review of properties that are important in creating the illusion of 3D
* [Post Processing](/keyconcepts/3d-design-guidelines/post-processing.md): How to use post-processing and other camera effects
* [Performance](/keyconcepts/3d-design-guidelines/performance.md): Benchmark information on when the illusion starts to break down
