Perlin Noise (with implementation in Python)

One of the most important algorithms in computer graphics and procedural generation is Perlin Noise. Perlin Noise is an algorithm that generates textures and terrain-like images procedurally (without the need for an artist to manually create the images).

Euler’s Polyhedron Formula

In this article, we have explored Euler’s Polyhedron Formula in depth with examples, proof and applications in real life problems.

Algorithms

Parallel Bubble Sort

In this article, we have explored how to implement Bubble Sort in parallel on multiple threads / cores. We have presented two approaches: one is slower than the sequential approach but the other approach is significantly faster than all other approaches for large input.
