Vulkan Cookbook

How to do it...

1. Prepare Vulkan resources as described in the Rendering a geometry with a vertex diffuse lighting recipe.
2. Load texture data from a file with a normal map (refer to the Loading texture data from a file recipe from Chapter 10, Helper Recipes).
3. Create a two-dimensional combined image sampler that has a color aspect and format (in example VK_FORMAT_R8G8B8A8_UNORM) and supports VK_IMAGE_USAGE_SAMPLED_BIT and VK_IMAGE_USAGE_TRANSFER_DST_BIT usages (refer to the Creating a combined image sampler recipe from Chapter 5, Descriptor Sets).
4. Copy data loaded from a normal map into the created image using a staging buffer (refer to the Using staging buffer to update an image with a device-local memory bound recipe from Chapter 4, Resources ...
