Get some parameters from shader matrix.

```hlsl

float3 cameraForward = -unity_MatrixV._m02_m12_m22;

float3 objectScale = float3(length(unity_ObjectToWorld._m00_m10_m20), 

                            length(unity_ObjectToWorld._m01_m11_m21),

			    length(unity_ObjectToWorld._m02_m12_m22));

float3 worldPosition = unity_ObjectToWorld._m03_m13_m23;

float4 clipPosition = UnityWorldToClipPos(unity_ObjectToWorld._m03_m13_m23);

float2 viewportPosition   = (clipPosition.xy + 1) * 0.5;

       viewportPosition.y = 1 - viewportPosition.y;

```
