Learn how to add realism to a 3D model by using Normal Mapping techniques. Learn how to calculate the tangent and bitagent vectors necessary to create a Normal Map space.
A skybox is a panoramic view representing a scenery. It can add realism to your game at a low performance cost. Learn what a skybox is, how it works and how to implement it using OpenGL ES.
Learn how to simulate light in OpenGL shaders and light up a 3D model. Learn how the four categories of light: diffuse, specular, ambient and emissive interacts differently with surfaces in computer graphics.
Before a 3D character appears on a screen, it is transformed into several coordinate systems. Learn more about the main coordinate system transformations a character goes through.
Learn about OpenGL Shaders, how they transmit data from the CPU to the GPU. Learn how they are compiled and linked. How they are used to apply textures to 3D models and how they can light a scene.
