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 convenience for:

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

Example

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();

Building

Requires CMake and Vulkan installed on your system.

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

To test, glfw and Catch2 are used 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
