Earthsim Pre Alpha: 0.3 (June 2022)

  • First basic version of land Editor for testing
    • Load/Save sim files
    • Create and modify ‘layers’ of land edits that are applied to the land.
    • Export landscapes as png height maps
  • Terrain Model
    • Real-time Sand, Earth, Gravel slippage
    • Thermal rock erosion into Gravel
    • Water dynamic flow
  • Simple atmosphere model
    • Water evaporation is a constant affected by temperature
    • Temperature is constant over the land and falls off by land height
  • Visualizer
    • High performance tile landscapes
    • Realtime edge cross sections
    • Basic lighting/shadows
    • Simple HDR/Tone mapping
    • Simple background clouds and skybox generation

Earthsim work in progress and future features

The next 0.4 alpha update discussed in this post is expected to be out for February 2024. Some other features we are actively working on are listed below.

  • Plants & Trees that grow and spread depending on soil and rock types
  • water ground penetration and subsurface water flow
Early version of the earthsim biosphere running on the landscape. Upto 1 million trees so far

Feature development track:

  • Vegetation
    • Users can pick & seed various vegetation types anywhere within a radius and see things start to grow. Seeds get dropped, fall downhill and are also moved by water flow (some seed types are more adapted to water transport).
    • Seeds only germinate if conditions are right so plants spread over the land by where they like to grow. Water, temperature and soil quality factors all are processed in the germination and growth models.
  • Wind simulation & Atmospheric rendering
    • Clouds and rain

Machine Specs

Minimum Spec

CPU: 4 Core with AVX2, 16GB Main memory

GPU: Discrete GPU with 8GB memory

This spec can handle landscapes up to 4k in real time, though 2k landscapes will be more comfortable at high fps.

Recommended Spec

CPU: 8 Core with AVX2, 16GB Main Memory

GPU: 8 GB memory

This spec can handle landscapes of up to 4k in real-time. All game levels will run very well with this spec:

Beyond playing the game, if you are intending to use Earthsim for editing and simulation of extra large landscapes (8k and 16k) in real time – 60Hz framerates, 16 or more cores are required.

A GPU with more than 8 GB memory and higher performance will enable higher res rendering and higher resolution atmosphere/smoke/clouds for volumetric atmospheric raytracing effects.
