So I need to create a program that converts an image/scene into smiley faces. The basic idea is this; I will have a scene with an image in it, and I want to create a shader or script that can turn that image into an array of :) faces. Similar to this, except instead of hexagons it would be :)

I managed to create a simple shader that turns an image into a mosiac, but I don't know I how I would turn it to smileys from there. The mosiac code
Shader "STYLY/Examples/Mosaic" {
Properties{
_MainTex("Texture", 2D) = "white" {}
[Space]
_Color("Main Color", Color) = (1,1,1,1)
[HDR]_EmissionColor("Emission Color", Color) = (0,0,0,1)
_MosaicResolution("Mosaic Resolution", Range(2, 128)) = 32
_MosaicResolutionX("X Mosaic Resolution", Range(1, 4)) = 1
_MosaicResolutionY("Y Mosaic Resolution", Range(1, 4)) = 1
[Space]
_Glossiness("Smoothness", Range(0,1)) = 0
_Metallic("Metallic", Range(0,1)) = 0
}
SubShader{
Tags { "RenderType" = "Opaque" }
LOD 200
CGPROGRAM
#pragma surface surf Standard fullforwardshadows
#pragma target 3.0
sampler2D _MainTex;
struct Input {
float2 uv_MainTex;
};
half4 _Color;
half4 _EmissionColor;
half _Glossiness;
half _Metallic;
int _MosaicResolution;
int _MosaicResolutionX;
int _MosaicResolutionY;
#define MOSAIC (_MosaicResolution * float2(_MosaicResolutionX, _MosaicResolutionY))
// Surface Shader
void surf(Input IN, inout SurfaceOutputStandard o) {
float2 uv = IN.uv_MainTex;
uv = floor(uv * MOSAIC) / MOSAIC;
fixed4 c = tex2D(_MainTex, uv);
o.Albedo = c.rgb * _Color;
o.Emission = c.rgb * _EmissionColor;
o.Metallic = _Metallic;
o.Smoothness = _Glossiness;
o.Alpha = 1.0;
}
ENDCG
}
FallBack "Diffuse"
}
So my question is, how would I, instead of making the images squares, make them in the shape of :) ?
