3D on the web with Three.js

After a third round of refinement with Opus 5.5 at medium (middle reasoning setting), Blender (a 3D program), an image-generation AI and three.js (a web 3D tool) were combined into a game that runs directly in the browser. The screen shows a character standing on a skyscraper rooftop and a small map at the bottom right.

Making a game used to mean moving between many tools. One model stitched them together into a result you can open without installing anything.

This scene was built with Three.js (a JavaScript tool for drawing 3D in a web browser). You steer a boat down a river through Japanese scenery. The weather changes and the light shifts between day and night. It has reflections on the water, a pagoda, cherry trees and 3D people, and you can try it right away on a public site.

A 3D scene with water reflections, physics, weather and buildings can be made to run right in the browser with no install.

Using the web 3D library Three.js, it made a scene where a building grows from its first line into massing, then details, then a finished house.

It turns the progress of an architectural design into an animation.

In Three.js, it computed fur movement on the graphics card (GPU) and made a cat that looks touchable from a single prompt.

Even demanding graphics, with every strand of fur moving, come out in one go.

To celebrate the Opus 5.5 launch, a scene of a pelican riding a bicycle was built with Three.js (a JavaScript tool for drawing 3D in a web browser). The first frame of the video looks down on a city packed with high-rise buildings topped with rooftop water tanks.

A 3D city scene with hundreds of buildings is now something you can casually make to celebrate launch day.

A 3-minute look at a Spider-Man-style 3D game made with Opus 5.5 Medium and Three.js (a JavaScript tool for drawing 3D on the web). The 3D models, textures (surface patterns) and animations in this game of roaming city rooftops were all made from scratch.

Without premade art or models, one person working with AI can build an action game set across a city.

Opus 5.5 built a basketball game like NBA 2K using Three.js (a tool for drawing 3D in the web browser) and Genex's game development tools for agents (AI that works through multiple steps on its own). In an arena with stands and a scoreboard, you move players and take shots, and a shot timing gauge judges each shot.

The feel of a sports game from a big studio can move into a web game you can play right away from a single link.

From a single short prompt, Opus 5.5 made a sand art animation (pictures drawn by scattering and sweeping sand). It added the voice and sound effects itself, without the 3D program Blender or the web 3D tool Three.js, and the result was never edited.

A short video with drawing, voice and sound can come from a single request, with no video tools.

A first-person game was built with Three.js, a tool for drawing 3D on the web. You carry a torch and a sword and walk along a village road to a distant castle. It took 40 minutes, including the music and art assets generated with an image generation AI.

Even with the music and art handed off too, a game with a real atmosphere comes out in under an hour.

Using Opus 5.5 and Three.js (a tool for drawing 3D in the browser), a No Man's Sky-style space game was made from a single prompt. It has more than 80 planets, each with different terrain, minerals, alien creatures and weather, and you can leave the ship and walk around.

A large game that covers everything from flying a spaceship to exploring planets can be made with a single request.
