Public Member Functions
template<typename T>
std::optional< glm::dvec3 >	operator() (const AccessorView< AccessorTypes::VEC3< T > > &value)
	Attempts to obtain a glm::dvec3 at the given index from an accessor over a vec3. The values will be cast to double and, if applicable, normalized based on std::numeric_limits<T>::max(). If the index is invalid, std::nullopt is returned instead.

Public Attributes
int64_t	index
	The index of the normal to obtain.

Detailed Description

Visitor that retrieves the normal from the given accessor type as a glm::dvec3.

There are technically no invalid normal values, so std::nullopt is used to denote an erroneous value.
