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);
}
