Overview

This guide describes how to improve a device's battery life by reducing device energy use, increasing application performance, and preventing thermal throttling by using specific aspects of 3D rendering to accelerate performance in 2D applications.

This guide was created to help application developers learn how to optimize the performance of their 2D application on a mobile device.

By the end of this guide, you will understand the main causes for inefficiencies in 2D rendering, how to exploit the 3D Depth Testing tool for performance gains, the benefits of combining 2D sprites and 3D geometry in a 2D scene, and how to combine this technique for 2D User Interfaces (UI) in 3D scenes.

Before you begin

Before starting this guide, we recommend that you have a firm understanding of the following concepts:

  • Back-to-front render ordering.
  • Front-to-back render ordering.
