01 / TERRAIN
Procedural + Real-World Terrain
Generate stylized terrain, import or guide from real elevation data, stitch large regions, process heightmaps, and export directly into game-engine workflows.

Genadem is a procedural world-generation environment: real-world and procedural terrain, parametric architecture, road and city systems, and a physically-based material engine — rendered by GenRen, our own engine. The scene on the right is GenRen running live in your browser.

One Environment. Multiple World Systems.
Stop stitching together five different tools.
Genadem is built around a simple idea: terrain, architecture, roads, cities, and materials are parts of the same world. They should not require separate disconnected workflows.
02 / ARCHITECTURE
Parametric Buildings
Create architecture from procedural systems rather than static kits: facade logic, roof systems, zones, props, city-specific styles, and reusable building rules.
Explore Architecture →03 / CITY
Roads, Districts & Urban Systems
Generate roads, intersections, sidewalks, district logic, props, and building populations inside the same environment as the terrain they sit on.
Explore City Systems →04 / MATERIALS
PBR Materials + GenRen
Build, inspect, and preview physically-based materials with the same toolchain used by generated terrain and architecture.
Explore Materials →Genadem Desktop
The web tool is one feature. The desktop app is the world builder.
Terrain Studio gives anyone a useful entry point. Genadem Desktop is where the full procedural environment lives: terrain, buildings, roads, cities, materials, generators, editing tools, and the renderer that ties them together.

ARCHITECTURE
Procedural Buildings
City-specific styles, facade logic, procedural props, roof systems, setbacks, zones, and export-ready geometry.
TERRAIN
Terrain Generation Studio
Procedural styles, real-world references, erosion, multi-resolution workflows, terrain editing, and engine-ready export.
CITY
Road & City Generation
Road networks, sidewalks, intersections, props, district rules, and architecture population on generated terrain.
RENDERING
GenRen
Integrated PBR rendering for generated assets, materials, inspection, and final presentation.
GenRen Web · The Renderer
Every viewport on this site is the real renderer.
GenRen is the rendering engine inside Genadem Desktop. GenRen Web is its WebGL2 sibling — not an approximation, a port. The hero scene above, the Terrain Studio preview, and the Material Lab below all run on it, live in your browser.

1:1shader parity with GenRen desktop
Desktop-grade lighting
Cook-Torrance PBR, HDRI image-based lighting, and PCF sun shadows — the desktop shaders ported line-for-line, same BRDF, same tonemap constants.
Full post stack
ACES / AgX / Reinhard tonemapping, Karis bloom, half-res SSAO, and FXAA — the same post pipeline the desktop renderer runs, in your browser.
Material engine + weathering
Procedural PBR material packs baked straight from the GenRen desktop engine — with Heitz-Neyret stochastic de-tiling and parallax occlusion — plus in-shader age, wetness, damage, moss, and dust. One surface goes brand-new to twenty-years-old by parameters alone.
Own asset pipeline
GLB / glTF / OBJ / STL parsers written in-house, full PBR texture sets with the glTF packed-MR convention, triplanar projection, and detail normals.
Built for scale
Over a million triangles rendered in under a millisecond on desktop-class GPUs — headroom to spare for full terrain and city scenes.
Zero dependencies
No three.js, no frameworks, zero runtime dependencies. The entire renderer ships in about 21 KB gzipped — raw WebGL2 and math we own.
*Measured on an RTX 5090 with forced-sync frames; your mileage scales with your GPU.
Free Web Tool
Real-World Terrain Studio
Select anywhere on Earth, capture elevation data, preview the result in real-time 3D, and export game-ready heightmaps or meshes. No desktop install required.
GenRen Web · Live Renderer
Material Lab
GenRen's renderer, live in your browser: Cook-Torrance shading, real HDRI image-based lighting, and the full procedural weathering stack. Browse the material-engine packs — procedural PBR sets baked straight from the desktop engine, with stochastic de-tiling and parallax occlusion — or pick a preset, age the surface, move the sun, switch shapes, and drop your own texture maps onto the slots.
Choose Your Workflow
Whether you need a quick in-browser terrain heightmap or a full procedural urban environment, Genadem has you covered.
