Using mesh geometry data in Vulkan
No graphical application can survive without working with at least some geometry data. In this recipe, we will learn how to load meshes into Vulkan buffers using Assimp. We will use shader storage buffer objects (SSBOs) and implement the programmable vertex pulling (PVP) technique, similar to what we did in the Implementing programmable vertex pulling (PVP) in OpenGL recipe.
Getting ready
The implementation of programmable vertex pulling for Vulkan is quite similar to OpenGL's. Please revisit the Implementing programmable vertex pulling (PVP) in OpenGL recipe for more information. The complete source code for all the Vulkan recipes in this chapter can be found in Chapter3/VK02_DemoApp.
How to do it...
Let's load an indexed mesh with vertex and texture coordinates. The data format for the texture mesh is the same as it was in the OpenGL recipes:
- The following function loads a mesh via Assimp from a file into a Vulkan shader...
