Turn “X: Tim Jayas's Three.js Steam-Engine Prototype Prompt” into a bounded task entry with explicit inputs, runtime context, output format, and acceptance checks; confirm the source and model state before use.
Build a Three.js prototype of {{MACHINE}}, add {{CONTROLS}}, and use {{BACKGROUND}}; verify animation, controls, resizing, and console errors.Replace before running: {{MACHINE}}, {{CONTROLS}}, {{BACKGROUND}}
Deliver a runnable Three.js steam-engine prototype with visible controls and a repeatable preview.
Use a Grok 4.6 coding workspace with Three.js, the machine specification, control list, camera settings, and a local browser preview.
Model the main parts, expose each requested control, connect the controls to observable motion, and add a reset state. Run the preview at a fixed viewport and test every control twice.
Accept only when the prototype starts from a clean load, controls produce the intended motion, and the reset returns to baseline. If animation or assets fail, reduce the scene to a minimal demonstrator and report the missing dependency.
This is an editorial adaptation of a public Three.js prototype prompt; it is not a performance or visual-quality benchmark.
Create a 3d steam engine working prototype using three.js. use white theme background so main object is clearly visibleThe author used the same prompt to compare Grok 4.6 with Qwen3.8 Max, and said that Qwen3.8 Max performed strongly. Someone in the comments asked for the prompt, and the author published the text above.
Specify the output object: A 3D steam engine.
Specify the technology stack: Three.js.
Specify the interaction requirement: A working prototype.
Specify the visual condition: A white background to keep the main object clear.
Create a working 3D steam-engine prototype using Three.js.
Show the main moving parts clearly on a white background. Add start/stop controls and a speed control.
Keep the camera and lighting readable. Test that animation, controls, and resizing work without console errors, then return the runnable result.The original prompt is suitable for a quick capability comparison; the engineering version adds interaction and acceptance criteria, making it better suited to a real development task.
