Environment Illumination

Environment Illumination is applicable for all the AR scenes with models except for video features.

Part 1. Introduction

Environment Illumination makes it possible for virtual models to reflect the real environment textures.

Adding realistic reflections to achieve more immersive AR experience.

This tutorial is mainly to introduce how to process in Unity environment.

We assume that readers have basic experience in app development and unity usage.

For more unity3d usage information, please visit the official website of unity3d documentation.

You need to install and prepare your development environment as below before you start.

Unity3D of this tutorial: Unity 2017.4.13

In this tutorial we will set up Environment Illumination based on "VOID SLAM(Markerless)".

If you're not familiar with VOID SLAM, we suggest you read “VOID SLAM (Markerless)” first.

Select ARCamera, and look up in the “Inspector” area on the right side, setup “Void AR Behaviour (Script)” properties.

Right click the “Assets”, select “Create” from pop menu, and click [ Material ].

Then you create a "New Material" under the Assets directory.

Expand “GameObject”, then left-click on “New Material”, hold it down and drag it onto the “Sphere” model.

Select Sphere, look up in the “Inspector” area on the right side, and expand the “New Material” setting.

Setup “Metallic” and “Smoothness” in Shader to add reflect attribute to models.

With higher Metallic level the reflection is more vivid, adjust the level as you need.

Build Process please refer to tutorial “VOID SLAM (Markerless)”.

After building, you can run it in your mobile device.
