Procedural Terrain Generator with User-Defined Caves

Made by Namit Bhutani (2022B3A70885H) and Karthik Prakash (2022A7PS0022H)

This is a OpenGL-based procedural terrain and cave generator that utilizes noise-based 3D density fields and the Marching Cubes algorithm for rendering. For better visuals, basic Phong lighting along with volumetric fog effects are also implemented.

It uses compute shaders for GPU-accelerated performance along with a lightweight ImGui-driven viewer that lets you fly around the scene, tweak noise seeds and edit procedural caves in real time.
