AoS and SoA

Structure of arrays

• easier manipulation with packed SIMD instructions in most instruction set architectures

• allowing more data to fit onto a single cache line.

struct pointlist3D {
    float x[N];
    float y[N];
    float z[N];
};
struct pointlist3D points;
float get_point_x(int i) { return points.x[i]; }

Array of structures

struct point3D {
    float x;
    float y;
    float z;
};
struct point3D points[N];
float get_point_x(int i) { return points[i].x; }
