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 - ( In.x * In.x + In.y * In.y));
    float3 normalVector = float3(In.x, In.y, reconstructZ);
    Out = normalize(normalVector);
}
