This repository is a collection of simple applications using the Vulkan API. The source code is heavily commented and structured so that a beginner can start learning the basics of Vulkan.

The language used is C 11/14. All the code is available under the MIT license.

The code currently has been tested only on a Nvidia GTX 760 graphics card, using the official Vulkan drivers (Nvidia 364) on Linux Mint 17.3. The only windowing system currently supported is XCB; patches are welcome!

• 00 - Commons

  Not really a demo: it's a collection of functions common to all the other demos (object creation, initializations etc).

• 01 - Clearscreen

  This demo shows how to create a window using SDL2, create a Vulkan Instance, Physical Device, Device, Queue, Swapchain, Command Pool, Command Buffer, and submit commands to clear the screen with a specified RGB color.

• 02 - Triangle

  The famous Triangle "Hello World": this demo shows how to create a vertex buffer and transfer data to it, how to create a renderpass, a pipeline and framebuffers, and how to send simple drawing commands to the GPU.

• 03 - Double Buffering

  This demo shows how to enhance Demo 02 to do double buffering, so that the CPU can generate the next frame while the GPU renders/presents the previous one.

• 04 - Push Constants

  This demo adds Push Constants to Demo 03, to display a simple animation.

• 05 - Textures

  The classic rotating cube: this demo shows how to upload textures to the GPU and use them in rendering.

• 06 - Compute

  This demo shows how to use Vulkan's compute shaders, and how to synchronize the compute queue with the graphics queue to display the computed results.
