Intel Mesa Vulkan driver now supports shaderInt16
The Vulkan specification includes a number of optional features that drivers may or may not support, as described in chapter 30.1 Features. Applicatio

Working with lights and shadows – Part III: rendering the shadows
In the previous post in this series I introduced how to render the shadow map image, which is simply the depth information for the scene from the view

Working with lights and shadows – Part II: The shadow map
In the previous post we talked about the Phong lighting model as a means to represent light in a scene. Once we have light, we can think about impleme

Working with lights and shadows – Part I: Phong reflection model
Some time ago I promised to write a bit more about how shadow mapping works. It has taken me a while to bring myself to actually deliver on that front...
