Implementation

• Lambert Lighting, Blinn-Phong Lighting and Custom Lighting models.
• Standard Surface Shaders in Unity using the #pragma directive to define the surface function and the lighting model.
• Setting the Albedo property from a texture.
• Normals implemented using a Normal Map or "Bump Map".
• Fresnel shader implemented doing the dot scalar multiplication between the Normal and the IN.viewDir.
• Environment Mapping using a SkyBox or Cube Map, then using the Unity provided worldRefl vector to derive the texel using texCUBE.
• Combine Normal Maps and Environment Mapping, using the Unity provided INTERNAL_DATA macro and the WorldReflectionVector()
• Using the Binn-Phong lighting model in a Standard Surface Shader.
• Implementing a Custom Lambert Lighting model.
• Toon Shading implemented with a ramped Lambert lighting model and an Outline shader implemented in a second Pass.
• Utilizing the Standard, physically correct lighting model.
• Writing a custom unlit shader for manual implementation of Lambert Lighting, Ambient Illumination and Shadow Casting/Receiving.
