description: this file contains the definition of the step function for float, float2, float3, and float4 types, to match GLSL's behavior.
|
|
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);
