Detailed Description

Describes the memory layout of a single vertex in a VBO.

A VertexLayout is a list of VertexElements — each element maps one interleaved field (position, UV, normal …) to a numbered shader attribute.

The layout is created by Builder factory methods together with the vertex data and is then stored inside Mesh. When Mesh::Bind() is called, GraphicsAPI reads the layout to issue the matching glVertexAttribPointer calls, connecting the raw buffer bytes to the GLSL attribute slots.

Example interleaved vertex (pos + normal + UV) looks like:

| x y z | nx ny nz | u v | ← one vertex, stride = 8 floats

^--- offset 0 ---^--- offset 12 ---^--- offset 24
