Luna::clamp

Float4 clamp(const Float4 &vec, const Float4 &vec_min, const Float4 &vec_max)

Clamps the vector to the specified range.

This function performs the following operations:

[Float3](struct_luna_1_1_float3.md) result;
result.[x](struct_luna_1_1_float3_1a6b05cac69c0301ab972c27ce208373be.md) = vec.x    > vec_min.x ? vec.x    : vec_min.x;
