建立一個sphere，scale的x,y,z分別設定為30

建立一個SurfaceShader，右鍵Assets–>Create–>Shader–>InsideVisible

Shader "Custom/InsideVisible" {
 
Properties {
	_MainTex ("Base (RGB)", 2D) = "white" {}
}
 
SubShader {
	Tags { "RenderType"="Opaque"
 
 }
	Cull front    // ADDED BY BERNIE, TO FLIP THE SURFACES
	LOD 100
	
	Pass {  
		CGPROGRAM
			#pragma vertex vert
			#pragma fragment frag
			
			#include "UnityCG.cginc"
 
			struct appdata_t {
				float4 vertex : POSITION;
				float2 texcoord : TEXCOORD0;
			};
 
			struct v2f {
				float4 vertex :
 
 SV_POSITION;
				half2 texcoord : TEXCOORD0;
			};
 
			sampler2D _MainTex;
			float4 _MainTex_ST;
			
			v2f vert (appdata_t v)
			{
				v2f o;
				o.vertex = UnityObjectToClipPos(v.vertex);
				// ADDED BY BERNIE:
				v.texcoord.x = 1 - v.texcoord.x;				
				o.texcoord = TRANSFORM_TEX(v.texcoord, _MainTex)
 
;
				return o;
			}
			
			fixed4 frag (v2f i) : SV_Target
			{
				fixed4 col = tex2D(_MainTex, i.texcoord);
				return col;
			}
		ENDCG
	}
}
}

把sphere的shader設定為Custom/InsideVisible
