Astra 3D examples and prompts
Interactive Hyperloop demo
Build an interactive Three.js Hyperloop demonstration showing a transport pod, tube infrastructure and motion through the system.
Steam locomotive across the countryside
Model a steam locomotive in Three.js and animate it travelling through a countryside scene. Synchronize the wheel movement with the train's motion.
Browser racing physics in C# and WASM
Recreate a Trackmania-style racing physics system in C#, run it through WASM and render the course in Three.js. Use collidable track meshes and test vehicle handling.
Children's room and workspace planner
Reconstruct a child's room that doubles as a workspace from four corner photos and room dimensions. Show adult and child viewpoints, an overview and alternative furniture layouts.
Exploded desktop-computer atlas
Create an interactive 3D website that separates a desktop computer into 29 core components. Add animated disassembly and explanations for each part.
Delivery network with bridge closures
Build a 3D delivery simulation where closing bridges changes truck routes. Detect unreachable destinations and restore deliveries when a route reopens.
Rotatable 3D shogi board
Build a playable 3D shogi application with a freely rotatable board. Refine the board, pieces and interactions through successive reviews.
Interactive Lorenz attractor
Visualize two Lorenz-system trajectories with a tiny initial-position difference. Let viewers change the difference and scrub through time, while distinguishing numerical checks from exact long-term predictions.

How to use GPT-6 Astra for 3D
Looking for Astra prompts you can actually build from? Start with a 3D example that matches your task: a Blender model, a Three.js website, a browser game or an explorable world. Each entry pairs a visual result with an author, a source link and a prompt or a clearly identified source-derived brief.
A useful Astra 3D prompt defines what to make, which software to use, what should remain editable and how to check the result. Copy a starting point, change the subject and constraints, then test the same brief with GPT-6 Astra or another model. These are references to adapt, not a guarantee that one prompt reproduces an entire demo.
Best for
01
Astra Blender prompts: editable 3D scenes
For an Astra Blender prompt, name the objects, materials, lighting and camera. Ask for separate editable objects and a saved scene, then inspect the render from more than one angle.
02
Astra Three.js prompts: interactive websites
For an Astra Three.js prompt, describe the scene, mouse and touch controls, loading behavior and a target device. Include a playable loop when making a browser game.
03
Astra 3D game examples: worlds you can explore
Use the Unreal Engine and Unity examples to plan explorable worlds. Specify scale, collisions, camera movement and the files you need; a showcase video alone does not prove a project is ready to ship.
Prompt recipe
Write a better first draft
- 01
Specify editability
State which objects must remain separate, named and editable; otherwise a visually convincing shell may still be unusable.
- 02
Close the test loop
Ask the model to run the scene, inspect visible failures and repeat until concrete frame-rate, interaction and layout checks pass.
- 03
Stage long builds
For large worlds, split the work into districts, assemblies or milestones and approve each section before expanding scope.
Create detailed 3D assets
Give your next scene a character worth a closer look. Create detailed, textured 3D assets from an image or a few words.
Generate 3D Assets FreeGPT-6 Astra 3D prompts FAQ
Are these the exact prompts used in every Astra demo?
+
No. Every entry is labeled. “Verbatim” preserves wording published by the author; “source-derived brief” is a reusable prompt reconstructed from the public demo description. We do not claim access to prompts that were never published.
Can I try these prompts in other models?
+
Use them as references, not model-specific magic words. Keep the outcome and acceptance checks, then adapt the tool, asset budget, camera, controls and output format for Astra, Claude, Kimi or another model.
Which examples include source code or a live demo?
+
Use the With GitHub filter to find Astra 3D examples with public code, then open an example for its repository and available live demo. The open-source collection brings these projects together across models. Check each repository’s license and setup instructions before reuse.
