LYGIA Shader Library

Dependencies:

• lygia/math/make.cuh

Use:

<float> step(<float> a, <float> b);

<float2> step(<float2> a, <float2> b);

<float3> step(<float3> a, <float3> b);

<float4> step(<float4> a, <float4> b);

<float2> step(<float2> a, <float> b);

<float3> step(<float3> a, <float> b);

<float4> step(<float4> a, <float> b);
