先上图,等会再将研究心得发布,如果想一起研究我有源代码,要的回复
附上shader代码:
Shader "Toon/Basic Outline" {
Properties {
_Color ("Main Color", Color) = (.5,.5,.5,1)
_OutlineColor ("Outline Color", Color) = (0,1,0,1)
_Outline ("Outline width", Range (0.005, 0.01)) = .001
_MainTex ("Texture", 2D) = "white" {}
_BumpMap ("Bumpmap", 2D) = "bump" {}
}

#include "UnityCG.cginc"
struct appdata {
float4 vertex : POSITION;
float3 normal : NORMAL;
};
struct v2f {
float4 pos : POSITION;
float4 color : COLOR;
};
uniform float _Outline;
uniform float4 _OutlineColor;
v2f vert(appdata v) {
v2f o;
o.pos = mul(UNITY_MATRIX_MVP, v.vertex);
float3 norm = mul ((float3x3)UNITY_MATRIX_IT_MV, v.normal);
float2 offset = TransformViewToProjection(norm.xy);
o.pos.xy += offset * o.pos.z * _Outline;
o.color = _OutlineColor;
return o;
}
