(

)

const -> std::optional<std::span<const GlmVecType>>

Get zero-copy span view of GLM vector data.

Template Parameters

GlmVecType

GLM type (glm::vec2, glm::vec3, glm::vec4)

Returns

Optional span pointing to variant's internal memory

Returns std::nullopt if variant doesn't contain exactly GlmVecType
