Vertex

struct glen::Vertex

Individual vertex. Basic building block of a mesh. Contains various attributes which are useful for sending to the shader A vertex is structured in the following way:

Tuple location	Type	Name
0	Vec3	Position coordinates
1	Vec3	Color
2	Vec3	Normals
3	Vec2	UV Coordinates
4	Int	ID
5	Vec3	Tangent
6	Vec3	Bitangent
