Vulkan bindings for JavaScript

node-vulkan

This is a Vulkan API for node.js.

The bindings are machine generated and provide an API to interact from JavaScript with the low-level interface of Vulkan. The API of this project strives to be as close as possible to Vulkan's original API.

Note: This is an early experiment, use with honor!

Preview:

Structure:

generator: code for binding generation
generated: the generated binding code
examples: contains a triangle and cube demo
lib: required third party libs

Requirements:

node.js >= v10.9.0

Generator:

Installation:

Windows:

Make sure you have either Visual Studio >= 15 installed or use

npm install --global --production windows-build-tools

Install the Vulkan SDK from here

Clone this repo

git clone git@github.com:maierfelix/node-vulkan.git

Install dependencies

npm install

API:

Syntax:

npm run [script] [flag] [value]

Flags:

 [-vkversion] [version]: The vulkan version to generate bindings for

Usage:

Generation:

You can specify a version to generate bindings for like this:

npm run generate -vkversion=1.1.82

Make sure the specified version to generate bindings for can be found here
The binding specification file gets auto-downloaded and is stored in generate/specifications/{vkversion}.xml
The generated bindings can then be found in generated/{vkversion}/

Building:

You can build the generated bindings like this:

npm run build -vkversion=1.1.82

The compiled bindings can then be found in generated/{vkversion}/build

Syntactic Sugar:

The API gives you some sugar to write things quicker, but still gives you the option to write everything explicitly

sType auto-filling

sType members get auto-filled, but you can still set them yourself

let appInfo = new VkApplicationInfo();
appInfo.sType = VK_STRUCTURE_TYPE_APPLICATION_INFO;

Becomes:

let appInfo = new VkApplicationInfo(); // sType auto-filled

Object based Structure creation

Instead of:

let offset = new VkOffset2D();
offset.x = 0;
offset.y = 0;
let extent = new VkExtent2D();
extent.width = 640; extent.height = 480;
let renderArea = new VkRect2D();
renderArea.offset = offset;
renderArea.extent = extent;

You can write:

let renderArea = new VkRect2D({
  offset: new VkOffset2D({ x: 0, y: 0 }),
  extent: new VkExtent2D({ width: 640, height: 480 })
});
