PHP
Lesson 17 - This lesson is intended to get you aquainted with how to draw graphics using PHP. You’ll also learn how to color the vertices of a triangle.
Lesson 18 - In this lesson you’ll learn the basics of lighting. You’ll learn how to create and use a class in PHP and then how to apply N colored lights to a texture.
Lesson 19 - Now it’s time to introduce you to the concept of the normal and how it’s used to create more realistic lighting.
Lesson 20 - In this lesson we were going to learn about Perlin noise. But, after a bit of experimenting, the lesson learned is simply that PHP is not suited for Perlin noise. We’ll instead cover it when we hit C++.
Lesson 21 - In this lesson you will learn how to ray trace a sphere. It’s actually one of the easiest problems to solve according to Graphics Gems, page 388. It’s even easier when you have the answer right in front of you.
Lesson 22 - In this final PHP 3D tutorial we will explain how to set up and utilize a z-buffer so that multiple spheres can be rendered in any order and look correct.
