+# nuklear glfw vulkan
+
+## Theory of operation
+
+The nuklear glfw vulkan integration creates an independent graphics pipeline that will render the nuklear UI to separate render targets.
+The application is responsible to fully manage these render targets. So it must ensure they are properly sized (and resized when requested).
+
+Furthermore it is assumed that you will have a swap chain in place and the number of nuklear overlay images and number of swap chain images match.
+
+This is how you can integrate it in your application:
+
+```
+/*
+Setup: overlay_images have been created and their number match with the number
+of the swap_chain_images of your application. The overlay_images in this
+example have the same format as your swap_chain images (optional)
+*/
+    struct nk_context *ctx = nk_glfw3_init(
+        demo.win, demo.device, demo.physical_device, demo.indices.graphics,
+        demo.overlay_image_views, demo.swap_chain_images_len,
+        demo.swap_chain_image_format, NK_GLFW3_INSTALL_CALLBACKS,
+        MAX_VERTEX_BUFFER, MAX_ELEMENT_BUFFER);
+[...]
+/*
+in your draw loop draw you can then render to the overlay image at
+`image_index`
+your own application can then wait for the semaphore and produce
+the swap_chain_image at `image_index`
+this should simply sample from the overlay_image (see example)
+*/
+nk_semaphore semaphore =
+    nk_glfw3_render(demo.graphics_queue, image_index,
+                    demo.image_available, NK_ANTI_ALIASING_ON);
+    if (!render(&demo, &bg, nk_semaphore, image_index)) {
+        fprintf(stderr, "render failed\n");
+        return false;
+    }
+```
+
+You must call `nk_glfw3_resize` whenever the size of the overlay_images resize.
+
+## Using images
+
+Images can be used by providing a VkImageView as an nk_image_ptr to nuklear:
+
+```
+img = nk_image_ptr(demo.demo_texture_image_view);
+```
+
+Note that they must have SHADER_READ_OPTIMAL layout
+
+It is currently not possible to specify how they are being sampled. The nuklear glfw vulkan integration uses a fixed sampler that does linear filtering.

+Contrary to OpenGL Vulkan needs precompiled shaders in the SPIR-V format which makes it a bit more difficult to inline the shadercode.
+
+After executing `make` the result should be a self contained `nuklear_glfw_vulkan.h`. Copy the result file to the parent directory and the "release" should be done.
+
+You will need to have `xxd`, `glslc` and `awk` installed for this.
