Assumptions and prerequisitesĮach lesson in this series builds on the lesson before it.
In OpenGL ES 2, we need to implement our own lighting algorithms, so we will learn how the math works and how we can apply it to our scenes. In this lesson, we’re going to learn how to implement Lambertian reflectance using shaders, otherwise known as your standard diffuse lighting.
Welcome to the second tutorial for Android.
