Introduction

The Vulkan Samples is collection of resources to help you develop optimized Vulkan applications.

If you are new to Vulkan the API samples are the right place to start. Additionally you may find the following links useful:

• Vulkan Guide
• Get Started in Vulkan

Performance samples show the recommended best practice together with real-time profiling information. They are more advanced but also contain a detailed tutorial with more in-detail explanations.

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

Samples

• Listing of all samples available in this repository

General information

• Project Basics
  • Controls
  • Debug window
  • Create a Sample
• Vulkan Essentials
  • How does Vulkan compare to OpenGL ES? What should you expect when targeting Vulkan?
• Misc
  • Driver version
  • Memory limits

Setup

Clone the repo with submodules using the following command:

git clone --recurse-submodules https://github.com/KhronosGroup/Vulkan-Samples.git
cd Vulkan-Samples

Follow build instructions for your platform below.

Build

Supported Platforms

• Windows - Build Guide
• Linux - Build Guide
• macOS - Build Guide
• Android - Build Guide

Usage

The following shows some example command line usage on how to configure and run the Vulkan Samples.

# Run Swapchain Images sample
vulkan_samples swapchain_images

# Run AFBC sample in benchmark mode for 5000 frames
vulkan_samples --sample afbc --benchmark 5000

# Run bonza test offscreen
vulkan_samples --test bonza --hide

# Run all the performance samples
vulkan_samples --batch performance

# Run Swapchain Images sample on an Android device
adb shell am start-activity -n com.khronos.vulkan_samples/com.khronos.vulkan_samples.SampleLauncherActivity -e sample swapchain_images
