搭建工程
新建工程，安裝Universal RP，我的Unity版本是2022.2

記得勾選DepthTexture和OpaqueTexture，之後會用到

新建Shader

添加UV，法線等信息，用於後續計算
struct appdata
{
float4 vertex : POSITION;
float2 uv : TEXCOORD0;
float3 normal : NORMAL;
};
struct v2f
{
float4 vertex : SV_POSITION;
float2 uv : TEXCOORD1;
float3 normal : TEXCOORD2;
float3 worldPos : TEXCOORD3;
float4 screenPos : TEXCOORD4;
float4 localPos : TEXCOORD5;
};
v2f vert (appdata v)
{
v2f o;
o.vertex = TransformObjectToHClip(v.vertex.xyz);
o.uv = v.uv;
o.normal = TransformObjectToWorldNormal(v.normal);
o.worldPos = TransformObjectToWorld(v.vertex.xyz);
o.localPos = v.vertex;
o.screenPos = o.vertex;
#if UNITY_UV_STARTS_AT_TOP
o.screenPos.y *= -1;
#endif
return o;
}
