Biomes

Biomes is Marpi's compact WebGL terrain toy: randomize a noise-built field, then reshape it with wave, height, and color controls. It is closer to a creative sketchbook than a full modeling suite, but the PLY export gives a satisfying escape hatch for experiments worth keeping.

What is Biomes?

The premise is wonderfully narrow. Biomes builds a square field of 3D bars from layered noise and lets a small control panel push the result toward ridges, plateaus, pits, or stranger synthetic geology. Two sets of width and depth controls change the large forms, a height slider shifts the terrain, and three color pickers repaint its vertical range. Randomize is the fast route to a fresh formation; Download saves the current shape as a PLY file. The public source is refreshingly legible about the machinery—Simplex noise feeding an ECharts GL scene—so this feels as much like an open creative-coding specimen as a finished tool.

What you can do there

• Randomize a noise-built terrain
• Tune wave dimensions, height, and colors
• Download the generated shape as a PLY file

Why we picked it

Biomes turns a few understandable parameters into a broad generative playground without burying the interesting part under menus. The combination of instant randomization and export makes it more than a passive WebGL demo: a promising terrain can leave the browser and continue its odd little life elsewhere.

How to get the most from it

Start with Randomize until the large silhouette catches your eye, then tune wave width and depth before touching the colors. Height is useful for pushing a quiet surface toward sharper relief. If a result feels worth revisiting, use Download to save the PLY rather than trusting the next random roll.

Good to know

Use a desktop browser with WebGL. The public source explicitly replaces the experiment on Android with a desktop request, and other mobile behavior was not verified. The page includes a Google Analytics call; accessibility, audio, current export compatibility, and image reuse rights still need review.
