Vk-Bootstrap

A Vulkan utility library meant to jump start a Vulkan Application

This library simplifies the tedious process of:

• Instance Creation
• Physical Device Selection
• Device Creation
• Getting Queues
• Swapchain Creation

It also adds several conveniences for:

• enabling validation layers
• setting up a debug callback
• selecting a gpu based on a small set of common criteria

Example

#include "VkBootstrap.h"

void device_init()
{
    vkb::InstanceBuilder builder;
    builder.setup_validation_layers()
           .set_app_name ("example")
           .set_default_debug_messenger ();
    auto inst_ret = builder.build();
    if (!inst_ret.has_value()) {
        // error
    }
    vkb::Instance inst = inst_ret.value();

    vkb::PhysicalDeviceSelector selector{ inst };
    selector.set_surface (/* from user created window*/)
            .set_minimum_version (1, 0)
            .require_dedicated_transfer_queue();
    auto phys_ret = selector.select ();
    if (!phys_ret.has_value()) {
        // error
    }
    vkb::PhysicalDevice physical_device = phys_ret.value();

    vkb::DeviceBuilder device_builder{ physical_device };
    auto dev_ret = device_builder.build ();
    if (!dev_ret.has_value()){
        // error
    }
    vkb::Device device = dev_ret.value();

    VkQueue graphics_queue = get_queue_graphics(device).value();
    VkQueue compute_queue = get_queue_compute(device).value();
    VkQueue transfer_queue = get_queue_transfer(device).value();
}

Using this library

Simple

Copy the src/VkBootstrap.h and src/VkBootstrap.cpp into your project

With git-submodule + CMake

add this project as a git-submodule

git submodule add https://github.com/charles-lunarg/vk-bootstrap

Then add the project with cmake

add_subdirectory(vk-bootstrap)

Manually Building

git clone https://github.com/charles-lunarg/vk-bootstrap
cd vk-bootstrap
mkdir build
cd build
cmake ..

To test, glfw and Catch2 are needed and automatically included using git submodules.

In the project directory, run

git submodule update --init

to get the required dependencies for testing setup.

Then return to the build directory and enable tests with VK_BOOTSTRAP_TEST

cmake ../path/to/vk-bootstrap/ -DVK_BOOTSTRAP_TEST=ON

Todo's

• Package library to be usable
• More examples
• Testing
• Documenting API
• Fleshing out device configuration
