This part of the tutorial presented a way to use textures (combined image samplers, in fact) inside shaders. To do this we created an image and allocated and bound a memory to it. We also created an image view. Next, we copied data from a staging buffer to the image to initialize its contents. We also created a sampler object that defined a way in which image data was read inside shaders.
This code and accompanying article (see References below) cover development of a flocking algorithm, which is then demonstrated as schools of fish via two applications. The first application was developed to run on a multi-threaded CPU, and the second to perform physics calculations on the GPU.
This software example demonstrates how to use multi-core technologies to edit images. There are two parts to this project, a .NET Windows application front end written using C# and Windows Presentation Foundation (WPF) and a C++ DLL which is responsible for the actual manipulation of the image.
