1. A PVRShaman (.POD) workspace is provided as an example in the Chapter_10/PVR_LinearFog folder that demonstrates the fog computation. Figure 10-4 is a screenshot of the workspace. PVRShaman is a shader development integrated development environment (IDE) that is part of the Imagination Technologies PowerVR SDK downloadable from http://powervrinsider.com/. Several subsequent examples in the book use PVRShaman to demonstrate various shading techniques.
2.
In this section, we provide an example 364 Chapter 14: Advanced Programming with OpenGL ES 3.0 of evaluating ambient, diffuse, and specular lighting on a per-fragment basis. This example is a PVRShaman workspace that can be found in Chapter_14/PVR_PerFragmentLighting, as pictured in Figure 14-1. Several of the examples in this chapter make use of PVRShaman, a shader development integrated development environment (IDE) that is part of the Imagination Technologies PowerVR SDK (downloadable from http://powervrinsider.com/).
