ICG 2017 Fall Homework1 Guidance
網媒所碩二 陳卓晗
Requirements
Flat, Gouraud, and Phong shading with Phong illumination model i n shaders. You can demonstrate the three shading computation in a single object. (3pts)
Enable multiple shaders and transformation on multiple objects in a scene. You are free to use those provided model files and arrange them to form the scene on your own style. You must show the thre e shading simultaneously on different objects in your scene. (3pts)
More than 2 objects & more than 2 light sources
Bonus: Special effects on animation

Shading
Flat Shading: Constant normal on the whole surface
Gouraud Shading: Different vertex normal, interpolated ve rtex color on a fragment
Phong Shading: Different vertex normal, interpolated vert
ex normal on a fragment

Shaders
// gl_Position is a built-in variable, it is the output of the vertex shader
// another output pass to fragment shader
// gl_FragColor is a built-in variable, it is the output of the fragment shader
