Normal Reconstruct Z Node

Description

Derives the correct Z value for generated normal maps using a given X and Y value from input In.

Ports

Name	Direction	Type	Description
In	Input	Vector 2	Normal X and Y value
Out	Output	Vector 3	Output value

Generated Code Example

The following example code represents one possible outcome of this node.

void Unity_NormalReconstructZ_float(float2 In, out float3 Out)
{
    float reconstructZ = sqrt(1.0 - saturate(dot(In.xy, In.xy)));
    float3 normalVector = float3(In.x, In.y, reconstructZ);
    Out = normalize(normalVector);
}
