Introduction

The Vulkan Best Practice for Mobile Developers is collection of resources to help you develop optimized Vulkan applications for mobile platforms.

Goals

• Create a collection of resources that demonstrate best-practice recommendations in Vulkan
• Create tutorials that explain the implementation of best-practices and include performance analysis guides
• Create a framework that can be used as reference material and also as a sandbox for advanced experimentation with Vulkan

Disclaimer: This project covers advanced Vulkan concepts. If you are new to Vulkan here are a few links to get you started:

• Beginners Guide to Vulkan
• Get Started in Vulkan

Tutorials

• General
  • Controls
  • Create a Sample
• Vulkan Essentials
  • How does Vulkan compare to OpenGL ES? What should you expect when targeting Vulkan?
• Vulkan Swapchains
  More detailed look at swapchains, and how you might want to use them
  • Appropriate use of N-buffering
  • Appropriate use of surface rotation
• Pipelines
  • Use of pipeline caches to avoid startup latency
• Render Passes
  • Appropriate use of load/store operations, and use of transient attachments
• Render Subpasses
  • Benefits of subpasses over multiple render passes, use of transient attachments, and G-buffer recommended size
• Command Buffers
  • Allocation and management of command buffers
• AFBC
  • Appropriate use of AFBC

Setup

Clone the repo with submodules using the following command:

git clone --recurse-submodules https://github.com/ARM-software/vulkan_best_practice_for_mobile_developers.git
