How can I implement triple buffering to reduce latency in my project?

Implementing triple buffering involves managing three buffers: a front, a middle, and a back buffer. Here's a conceptual example in C++:

1#include <array>
2#include <iostream>
3
4// Simplified buffer
5typedef std::array<int, 10> Buffer;
6
7void rotateBuffers(
8  Buffer*& front, Buffer*& middle, Buffer*& back) {
9  Buffer* temp = front;
10  front = middle;
11  middle = back;
12  back = temp;
13}
14
15int main() {
16  Buffer A, B, C;  // Three buffers
17  Buffer* frontBuffer = &A;
18  Buffer* middleBuffer = &B;
19  Buffer* backBuffer = &C;
20
21  // Example usage
22  // Assume backBuffer is filled with new data
23  rotateBuffers(
24    frontBuffer, middleBuffer, backBuffer);
25}

Implement this rotation logic at the end of your rendering loop, ensuring you manage the buffers correctly to minimize the delay between user input and visual feedback.
