find minimum and maximum coordinates of screen
Answers
This code in C# would provide you with the desired ans: struct appdata { float4 vertex : POSITION; float2 uv : TEXCOORD0; }; struct v2f { float2 uv : TEXCOORD0; float4 vertex : SV_POSITION; float4 screenPos : TEXCOORD1; }; v2f vert (appdata v) { v2f o; o.vertex = UnityObjectToClipPos(v.vertex); o.uv = v.uv; o.screenPos = ComputeScreenPos(o.vertex); return o; } fixed4 frag (v2f i) : SV_Target { float2 screenPos = i.screenPos.xy / i.screenPos.w; fixed4 col = fixed4(screenPos.xxx, 1); return col; }
