Is it possible to have a SoA Vertex Buffer in DirectX 11?

Hi! I'm wondering if it is possible to structure a Vertex Buffer in a SoA approach like this { x1, x2, x3 . . . xn, y1, y2, y3 . . . yn, z1, z2, z3 . . . zn } instead of the traditional AoS approach { x1, y1, z1, x2, y2, z2, x3, y3, z3 . . . xn, yn,…

How can I properly manage data in modern OpenGL while considering performance?

In modern OpenGL (3.x+), you create buffer objects which contain vertex attributes, such as positions, colors, normals, texture coordinatess, & indices. These buffers are then assigned to a corresponding vertex array object (VAO) which essentially…
