N=N1+N2

WebGL model數個參數

例如color和texture

webgl buffer種類

1.attribute

2.uniform

3.varying

shader有兩種

vertex shader和fragment shader

lights material → uniform

Normal attribute → vertex normal

vertex attribute → vertex coordinate

Shading & lighting是interchanged ambiguous

Lambertian reflection model

Phong reflection model

Lambertian reflectance

Specular reflection

ESSL (OpenGL ES Shading Language)

attribute 用於vertex shader和application之間

uniform的值value在object being processed物件處理中不改變其值

varying linkage a vertex shader 和a fragment shader

const->compile time constant

alpha透明度

vFinalColor[3]=1.0

vFinalColor.a=1.0

vFinalColor.w=1.0

vec3 vec4有3個與4個element元素
