## Repositories
|
|
|
|
Besides the current repository, you will also need to clone or download the following repositories:
|
|
|
|
* [shared_sources](https://github.com/nvpro-samples/shared_sources): The primary framework that all samples depend on.
|
|
* [shared_external](https://github.com/nvpro-samples/shared_external): Third party libraries that are provided pre-compiled, mostly for Windows x64 / MSVC.
|
|
|
|
The directory structure should be looking like this:
|
|
|
|
~~~~
|
|
C:\Vulkan\nvpro-samples
|
|
|
|
|
+---shared_external
|
|
+---shared_sources
|
|
+---vk_raytracing_tutorial_KHR
|
|
| +---ray_tracing__simple
|
|
| +---ray_tracing_...
|
|
| \---...
|
|

## Latest Vulkan SDK
|
|
|
|
This repository tries to always be up to date with the latest Vulkan SDK, therefore we suggest to download and install it.
|
|
|
|
**Vulkan SDK**: https://vulkan.lunarg.com/sdk/home
|
|
|
|
|
|
## Beta Installation
|
|
|
|
KHR ray tracing is still in Beta, therefore you will need the latest
|
|
Vulkan driver.
|
|
|
|
**Latest driver**: https://developer.nvidia.com/vulkan-driver
|
|
|
|
|
|
## CMake
|
|
|
|
The CMakefile will use other makefiles from `shared_sources` and look for Vulkan environment variables for the installation of the SDK. Therefore, it is important to have all the above installed before running Cmake in the
|
|
`vk_raytracing_tutorial_KHR` directory.
|
|
|
|
**_Note_**: If you are using your own Vulkan header files, it is possible to overide the default search path.
|
|
Modify `VULKAN > VULKAN_HEADERS_OVERRIDE_INCLUDE_DIR` to the path to beta vulkan headers.
|

|
## Starting From Extra Tutorial
|
|
|
|
All _extra_ tutorials are starting from the end result of the _first tutorial_. The directory of the _extra_ tutorials is the end result of doing it.
|
|
|
|
To start the tutorial from the begining.
|
|
|
|
* Make a copy of the ray_tutorial__simple (backup)
|
|
* Follow the tutorial by modifying ray_tutorial__simple |
