# 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
## Example
```cpp
vkbs::InstanceBuilder builder;
builder.setup_validation_layers()
.set_app_name ("example")
.set_default_debug_messenger ();
auto inst_ret = builder.build ();
vkbs::Instance inst;
if (inst_ret.has_value()) {
// successfully created instance
inst = inst_ret.value();
}
vkbs::PhysicalDeviceSelector(inst);
selector.set_surface (/* from user created window*/)
.set_minimum_version (1, 0)
.require_dedicated_transfer_queue();
auto phys_ret = selector.select ();
vkbs::PhysicalDevice phys;
if (phys_ret.has_value()) {
// successfully selected a sufficient physical device
phys = phys_ret.value();
}
vkbs::DeviceBuilder device_builder(phys_dev);
auto dev_ret = device_builder.build ();
if(dev_ret.has_value()){
// successfully created a vulkan device
}
```
## Building
Requires CMake and Vulkan installed on your system.
```bash
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
```bash
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`
```bash
cmake ../path/to/vk-bootstrap/ -DVK_BOOTSTRAP_TEST=ON
```
