Solved my first LC hard (Merge k Sorted Lists) in C++.
Nice to have the option to use the priority queue data structure which gives O(N log k) complexity.
When I practiced DSA in JS (previously), I'd usually merge two lists at a time, since JS doesn't have a built-in heap.

Ray marched a procedural terrain using value noise. This time, I removed the sphere SDF, colorized the terrain based on its normals, and added specular lighting.

Ray Marching Determinant Space Distortion
I finally figured out what a determinant represented (geometrically) thanks to 3B1B. Wanted to visualize it in a shader but couldn’t fix all the artifacts. May come back to this later. Here's a working demo for now.

Spent some time learning more about distance fog this week. Without it, we see weird artifacts like the distortion on the checkerboard plane.

Ray Marching Shadows with Post Processing Effects (part 4)
Since I've come this far already, figured I might as well learn how to compute the shadow of the triangle analytically using ray-plane intersection tests.

Realized the shadows looked off in the previous demo because I used directional lighting. Swapped in a point light, but now I see more graphics artifacts because the rays are hitting the wireframe and light sphere.

GLSL Shader Experiment 09: More Voronoi Noise
I finally figured out how to smoothly transition between grayscale, classic, Manhattan distance, Worley, and multi-layered Worley noise! Learning C++ and SFML to build this shader engine has been pretty fun too.
