Emil-Harvey/Proc_Terrain_Base: Procedural Terrain, Geography Simulation (github.com)

About

A side-project I began working on in 2021, as a way of learning about graphics shaders, directX11, earth's geography, and procedural generation. Fly around and explore an endless custom world.

Features

This is a list of features that have been implemented in some form or another

♦ Procedural generation of continental landscapes with tessellating quad-tree mesh 

♦ Seamless & endless exploration

♦ Create and export heightmaps to TGA files

♦ Procedural sea animation and texturing; specular lighting and Fresnel shading

♦ HD PBR texturing - albedo, specular, normal maps and heightmaps

♦ Procedural texturing based on biomes and simulated geographical features:

♦   temperature 
♦   humidity 
♦   slope and aspect of terrain 
♦   proximity to water 
♦   depth below sea 
♦   seasonal weather 
♦   latitudinal prevailing wind direction 

♦ Fallen snow adding to the displacement of the terrain mesh

♦ Tri-planar mapping for texturing steep slopes

♦ Day/night cycle based on global position, time of year and axial tilt,

♦ Fully adjustable time-scale from real-time to 1 day per second

♦ Procedural grass/foliage + wind effect

♦ Clouds, rain & weather effects

♦ 'Retro' colour shader (4-bit, 16-bit colour depth)

♦ Bayer dithering shader, white noise dithering

♦ Orthographic camera mode

Exporting Capabilities

Thanks to the added functionality of heightmap saving and exporting, you are now able to use the landscapes you create/discover wherever you wish, from 3D software to game engines.
