OpenSynaps - Hypnosis game

Introduction

OpenSynaps aims to create new states of consciousness to remedy disorders and fears. The applications make available various combined mental techniques such as breathing, relaxation, alpha waves, subliminal and operant conditioning. Thanks to the possibilities offered by Virtual Reality and its immediate immersion features, these techniques have a direct impact on the conscious and subconscious mind. OpenSynaps programs are also available as mobile applications.

Technologies used

This application was developed natively in C# using the Unity game engine.

As the use of virtual reality requires maintaining a very high image refresh rate (over 60 frames per second), particular attention had to be paid to optimization and performance, especially as the power of the Oculus Go corresponds to that of a cell phone.

The applications were developed in Unity. Particular attention was paid to performance. As the Oculus Go is a mobile virtual reality headset, the performance available is limited. What's more, when used intensively, it tends to heat up and shut down.

To alleviate these problems, the application was optimized by drastically reducing the number of Draw Calls and Graphics Passes. A number of graphics techniques were used: Static batching, Dynamic batching, Multithread rendering, Textures atlases, ASTC textures compression, Tree billboard, Meshbaking, Unlit texture, Static lightmap, Mesh terrain.
