lygia/math/frac)this file contains the definition of the floor function for float, vec2, vec33, and float4 types, to match HLSL's behavior.
Use:
<float|vec2|vec3|vec4> frac(<float|vec2|vec3|vec4> X)
#ifndef FNC_FRAC
#define FNC_FRAC
#define frac(X) fract(X)
#endif
Dependencies:
Use:
<float2|float3|float4> frac(<float2|float3|float4> value);
#ifndef FNC_FRAC
#define FNC_FRAC
inline __host__ __device__ float frac(float v) { return v - floorf(v); }
inline __host__ __device__ float2 frac(float2 v) { return make_float2(frac(v.x), frac(v.y)); }
inline __host__ __device__ float3 frac(float3 v) { return make_float3(frac(v.x), frac(v.y), frac(v.z)); }
inline __host__ __device__ float4 frac(float4 v) { return make_float4(frac(v.x), frac(v.y), frac(v.z), frac(v.w)); }
