Work Session 3

Super Mario Sunshine water

Goal

The goal of this work-session is to explore the power of textures. We will be using a texture as a lookup table to map values from our vertex lighting calculation onto a range authored by an artist.

Instructions

  1. Vertex Lighting:

    • Apply a simple vertex lighting effect. Because we are trying to achieve a stylized effect we’re going to use the diffuse portion of the Phong reflection model and ommit all specular lighting.

  2. Toonification:

    • To achieve the cel-shaded effect, we will sample from ZAtoon.png which will be used as a lookup map for our vertex lighting values.

  3. Color Tint:

    • Using the color palette mix between the highlight and shadow colors to give our object a stylized color tint.
