This commit lays the foundational groundwork for the Vulkan rendering backend.
Key changes include:
1. **Platform Layer (`rcore_desktop_glfw.c`):**
* `InitPlatformVulkan`: Implemented to correctly create a `VkInstance` with necessary GLFW extensions and validation layers (if `RLGL_ENABLE_VULKAN_DEBUG` is defined). It also creates a `VkSurfaceKHR` using GLFW. These handles are passed to the core Vulkan layer.
* `ClosePlatformVulkan`: Updated to properly destroy the `VkInstance` and `VkSurfaceKHR`.
2. **Vulkan Abstraction Layer (`rlvk.c`, `rlvk.h`):**
* `rlvkInit`: Implemented the core Vulkan setup:
* Physical device selection (preferring discrete GPUs).
* Logical device creation with graphics and present queues, and swapchain extension.
* Swapchain creation (images, image views).
* Render pass creation (with color and depth attachments).
* Depth buffer resource creation (image, memory, image view).
* Framebuffer creation for each swapchain image.
* Command pool and command buffer allocation (one per swapchain image).
* Synchronization primitives (semaphores for image acquisition/render completion, fences for command buffer completion).
* `rlvkClose`: Updated to destroy all Vulkan resources created in `rlvkInit` in the correct order.
* `rlvkBeginDrawing`: Implemented to handle frame synchronization (wait for fence, acquire next swapchain image), begin the command buffer, and begin the render pass (using the clear color set by `rlvkClearBackground`). Viewport and scissor are set.
* `rlvkEndDrawing`: Implemented to end the render pass, end and submit the command buffer (signaling appropriate semaphores and fence), and present the image. Handles frame advancement.
* `rlvkClearBackground`: Implemented to store the clear color you provide, which is then used by `rlvkBeginDrawing`.
With these changes, a raylib application compiled with `GRAPHICS_API_VULKAN` can initialize a Vulkan context, open a window, clear the background to a specified color, and shut down cleanly. Actual object rendering (shapes, textures, models) is not yet implemented in Vulkan and will be part of subsequent work.

raylib is a simple and easy-to-use library to enjoy videogames programming.
raylib is highly inspired by Borland BGI graphics lib and by XNA framework and it's especially well suited for prototyping, tooling, graphical applications, embedded systems and education.
NOTE for ADVENTURERS: raylib is a programming library to enjoy videogames programming; no fancy interface, no visual helpers, no debug button... just coding in the most pure spartan-programmers way.

basic example
This is a basic raylib example, it creates a window and draws the text "Congrats! You created your first window!" in the middle of the screen. Check this example running live on web here.
#include "raylib.h"
int main(void)
{
InitWindow(800, 450, "raylib [core] example - basic window");
while (!WindowShouldClose())
{
BeginDrawing();
ClearBackground(RAYWHITE);
DrawText("Congrats! You created your first window!", 190, 200, 20, LIGHTGRAY);
EndDrawing();
}
CloseWindow();
return 0;
}
build and installation
raylib binary releases for Windows, Linux, macOS, Android and HTML5 are available at the Github Releases page.
raylib is also available via multiple package managers on multiple OS distributions.
Installing and building raylib on multiple platforms
raylib Wiki contains detailed instructions on building and usage on multiple platforms.
- Working on Windows
- Working on macOS
- Working on GNU Linux
- Working on Chrome OS
- Working on FreeBSD
- Working on Raspberry Pi
- Working for Android
- Working for Web (HTML5)
- Working anywhere with CMake
Note that the Wiki is open for edit, if you find some issues while building raylib for your target platform, feel free to edit the Wiki or open an issue related to it.
Setup raylib with multiple IDEs
raylib has been developed on Windows platform using Notepad++ and MinGW GCC compiler but it can be used with other IDEs on multiple platforms.
Projects directory contains several ready-to-use project templates to build raylib and code examples with multiple IDEs.
Note that there are lots of IDEs supported, some of the provided templates could require some review, so please, if you find some issue with a template or you think they could be improved, feel free to send a PR or open a related issue.
learning and docs
raylib is designed to be learned using the examples as the main reference. There is no standard API documentation but there is a cheatsheet containing all the functions available on the library a short description of each one of them, input parameters and result value names should be intuitive enough to understand how each function works.
Some additional documentation about raylib design can be found in raylib GitHub Wiki. Here are the relevant links:
- raylib cheatsheet
- raylib architecture
- raylib library design
- raylib examples collection
- raylib games collection
