pxr_half::half GfHalf
A 16-bit floating point data type.
Definition: half.h:43
A metafunction which is equivalent to std::is_floating_point but allows for additional specialization...
Definition: traits.h:57
std::enable_if< std::is_same< Half, half >::value, size_t >::type hash_value(const Half &h)
Overload hash_value for half.
