Displaying dynamic detail with LODs

An LOD chain is simply a collection of versions of a single mesh, all optimized to be viewed at different distances. If the player is far away from the mesh, it can be rendered using the mesh with the smallest level of detail because the player can't see details from far away anyway. As the player gets closer, the LOD chain replaces the mesh with others in the chain that get progressively more detailed.

To see this technique in action, we'll tweak some Simplygon settings that will enable us to write out several different LODs in a chain at one time.

Delete your old compressed StanfordBunny mesh, leaving just the original behind. Reselect the original in your Hierarchy and go back to the Simplygon menu, but select the Advanced Settings tab instead of the Quick Start tab this time.

Under the LOD Chain Settings menu, you'll see a property called #LODs, which tells Simplygon how many different levels of detail to render. Set this value to 4 and...

Donovan

Jack Donovan is a 24-year-old software engineer living in Brooklyn, New York. He graduated from Champlain College in Burlington, Vermont with a BS in game programming and soon after joined IrisVR, a startup founded in Burlington to create oneclick software for architects to visualize models in virtual reality. IrisVR moved to New York City after being accepted into the startup incubator program Techstars and has since moved to an independent office in NoHo, where Jack continues to work. Jack also wrote OUYA Game Development By Example, a book focused on the basics of developing games for the Android-powered OUYA console. Both books use the Unity3D engine for development, which Jack has been using to develop games and software in since 2010.
