Double Buffering

Implementing Triple Buffering to Reduce Latency

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

Abstract art representing computer programming

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

#include <array>
#include <iostream>

// Simplified buffer
typedef std::array<int, 10> Buffer;

void rotateBuffers(
  Buffer*& front, Buffer*& middle, Buffer*& back) {
  Buffer* temp = front;
  front = middle;
  middle = back;
  back = temp;
}

int main() {
  Buffer A, B, C;  // Three buffers
  Buffer* frontBuffer = &A;
  Buffer* middleBuffer = &B;
  Buffer* backBuffer = &C;

  // Example usage
  // Assume backBuffer is filled with new data
  rotateBuffers(
    frontBuffer, middleBuffer, backBuffer);
}

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.
