04_texture_mapping

04_texture_mapping_win32

This basic Vulkan application follows the fourth chapter (Texture Mapping) of the excellent Vulkan Tutorial, building on the application at 03_uniform_buffers. It demonstrates:

• Loading the texture file, which is significantly different in Go from the C library used by the original tutorial
• Loading and transitioning the texture data to the GPU
• Creating an image sampler for the shader to use when accessing the texture
• Modifying the pipeline and shader to use the texture

This program (and all of the samples) were built both as a guide to using Vulkan with Go, and as a basic validation and test of the go-vk binding. Barring any design updates in go-vk as we move towards a 1.0 release (e.g. struct member naming conventions), this project should not have any material changes.

Building

Before running, be sure to go generate in the project root. This will compile the shaders with glslc.exe. That compiler is bundled with the Vulkan SDK. The go:generate annotations can be found in main.go.
