Generated Code Example

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

Default

void Unity_Reciprocal_float4(float4 In, out float4 Out)
{
    Out = 1.0/In;
}

Fast (Requires Shader Model 5)

void Unity_Reciprocal_Fast_float4(float4 In, out float4 Out)
{
    Out = rcp(In);
}
