Detailed Description

Describes one interleaved vertex attribute within a VBO.

Maps directly to a glVertexAttribPointer call:

• index → attrib location in the vertex shader.
• size → component count (1–4).
• type → GL data type (typically GL_FLOAT).
• offset → byte offset from the start of the vertex struct.
